NX-8 Alarm System

[ling_bin70]

I have this requirement from my customer.

There are one local NX-8 alarm panel c/w one NX-507 and one 8 ch
transmitter contact closure via single mode fiber optic to the remote 8 ch
receiver.

The remote, One NX-8 alarm panel c/w zone expander and NX-508 (Mimic Panel).

When there is an alarm from the local side, the LED and buzzer at the
minic panel (remote) are to be latched. The system reset at mimic panel
will only cut-off the buzzer and will not distinguish the alarmed LED.

once the alarmed zone at the local side is reset then the remote side need
to reset one more time to distinguish the lighted LED.

Please assist the above requirement.

Regards.

The remote, One NX-8 alarm panel c/w zone expander and NX-508 (Mimic Panel).

Which zone expander?

Please assist the above requirement.

Do you want help on the connections,the setup,etc.... please define.

What I got is this:

One local panel connected to 8 hardwired zones, outputs zone status events to the 7 relay module NX-507 (I think you need the 8 relay module NX-508 here).
The relay module feeds the inputs of an 8 channel transmitter and the 8 outputs travel through a single fiber to the remote panel.

The fiber connects to the 8 channel receiver, decodes the 8 lines and connects as hardwired zones to the remote panel.

So you have 8 initial real zones duplicating on two same NX-8 panels.

I don't understand the presence of a zone expander and the second relay module (for printing event logs?) on the remote side of the system so please explain.
Also I would like to know the distance between the two panels.

Tell me if I got everything right so I can help you further on your project.

Thanks for your reply. To explain further, I have total three Blocks within a base, said Block A, B and C.

Block A equipment comprises of One NX-8, 8 zone LED Keypad, Siren strobe light, NX-507 and a 8ch single mode contact closure fiber transmitter. (one door to be monitored)

Block B equipment comprises of One NX-8, 8 zone LED Keypad, Siren strobe light, NX-507 and a 8ch single mode contact closure fiber transmitter. (one door to be monitored)

Block C equipment comprises of One NX-8, NX-214 (for Further expansion), 24 zone LED Keypad, Siren, 2 X NX-508 and a 2 x 8ch single mode contact closure fiber Receiver.

Both Block A and block B status need to monitor by block C which is a custom make mimic panel. (Block C is the central monitoring station)

The status need to be monitor by block C mimic panel are AC Failure, System Low Battery and Box Tamper (local alarm panel). For  Blk A & B are system Arm, Zone Alarm, AC Failure and System Battery Low (remote alarm panel).

When there is an alarm from Block A or Block B, the LED and buzzer at the
minic panel (Block C) are to be latched. The system reset at mimic panel
will only cut-off the buzzer and will not distinguish the alarmed LED.

once the alarmed zone at Block A or Block B is reset then the remote side (Block C) need
to reset one more time to distinguish the lighted LED.

Please advise on the setup, connection and the programming portion.

The Distance between each alarm panel is about 15km.

Regards.

Both Block A and block B status need to monitor by block C which is a custom make mimic panel. (Block C is the central monitoring station)

The custom mimic panel takes it's info from the two NX-508 ?
Is this mimic panel made of leds and buzzers ?
You have a 24 zone LED keypad in Block C that is why I am asking the use of the mimic panel.

The status need to be monitor by block C mimic panel are AC Failure, System Low Battery and Box Tamper (local alarm panel). For  Blk A & B are system Arm, Zone Alarm, AC Failure and System Battery Low (remote alarm panel).

So you want the custom mimic panel to show:

for Block C  = AC,Battery and Box tamper
for Block A & B = Armed status, Zone Alarm ,AC and Battery
Is this right ?
For the Zone Alarm event ,you will know you have an alarm but not from which zone it was triggered.

Please tell me if all the above is correct so I can help you with connections and programming.
I assume you have no phone lines on sites A and B.
Some specs of the 2+2 transmitters/receivers would be helpfull.
I also assume you can connect the A and B blocks meaning panel,keypad,zones,siren and you want help connecting and configuring the two NX-507.

george

[ling_bin70]

Thanks for your valuable feedback.
The custom mimic panel takes it's info from the two NX-508 ? Sorry, dont get want you are requesting.
Is this mimic panel made of leds and buzzers ? Yes, including those equipment which mention below. Sorry miss out three kaba key switch for reset alarm purpose at all blocks.

So you want the custom mimic panel to show:

for Block C  = AC,Battery and Box tamper
for Block A & B = Armed status, Zone Alarm ,AC and Battery
Is this right ?
For the Zone Alarm event ,you will know you have an alarm but not from which zone it was triggered.
The A and B blocks meaning panel,keypad,zones,siren and you want help connecting and configuring the two NX-507.

Ans: All correct for the above.

Lastly, can NX alarm panel perform the below requirement?

When there is an alarm from Block A or Block B, the LED and buzzer at the
minic panel (Block C) are to be latched. The system reset at mimic panel
will only cut-off the buzzer and will not distinguish the alarmed LED.

once the alarmed zone at Block A or Block B is reset then the remote side (Block C) need
to reset one more time to distinguish the lighted LED.

As told before you should connect the two blocks A and B with the sensors (motion,contacts,etc) ,the keypad ,the NX-507, siren and strobe. The NX-507 is connected on the keypad bus just like a keypad (DATA COM POS terminals). Give the NX-507 module the address 24 (Dip switch 1 = ON , 2 = ON and 3 = OFF). Configure the system so it behaves the way you want (zone types, delays , keypad sounder etc). When you have everything ready you are going to connect the NX-507 outputs to the fiber optics transmitter. You did not mention what type of inputs this transmitter expects ,is it negative or positive control or both. I assume we can go along with negative control. For this, bridge the COM, 1COM, 2COM, 3COM and 4COM NX-507 terminals with jumper wires together. Then connect a wire from any of these terminals to a ground terminal on the transmitter. Then you need to connect 4 outputs. One for the ARMED status signal. One for the ALARM signal. One for the AC failure and one for LOW BATTERY signal. These should be connected from the 1NO , 2NO , 3NO and 4NO NX-507 terminals to 4 of the 8 transmitter inputs. This way whenever an event is activated it GROUNDS the corresponding transmitter input.

BLOCKS A & B NX-507 outputs configuration.
First you have to program the 4 different events for the 4 outputs.
For output 1 this is done at Location 0 (of the NX-507 not the panel) Segment 1
Since you want the first output to be the ARMED status the event is number 21 ARMED.
Press on the keypad:
* 8 9713 (9713 is the default installer code) to enter into program mode
24 # to enter into the module's locations (module address 24 = NX-507)
0#  to enter location 0 of the module

Now you are in Location 0 , Segment 1
You will see the LEDs of zones 6,4,2 and 1 lighting indicating a binary number.This is 101011 in binary and stands for number 43. This is the default event for this output and stands for ANY ALARM. Since you want event 21 press:

21 *  (* for saving your entry).
#      to exit Location 0
EXIT  to exit module address 24 (NX-507)
EXIT  to exit program mode

Likewise configure output 2 with event number 7 ANY SIREN or event number 5 BURGLARY siren only at Location 4.Press:

* 8 9713 24 # 4 # (Location 4 for event configuration of output 2)
press 7 or 5 and * for saving
# EXIT EXIT

Output 3 should be configured with event number 9 AC FAILURE at Location 8.
* 8 9713 24 # 8 # 9 * # EXIT EXIT

Output 4 should be configured with event number 10 SYSTEM LOW BATTERY at Location 12.
* 8 9713 24 # 12 # 9 * # EXIT EXIT

Now by default each output is configured to a zone, that is zone 1 is configured to output 1, zone 2 to output 2 etc.
Since we want to get ARMED status and ALARM information from any zone Segment 2 of Locations 0 , 4 , 8 and 12 needs to be a zero (0).
For Output 1:
* 8 9713 24 # 0 # you are in Location 0, Segment 1
press * to step to Segment 2
press 0 for your new entry (changing the default "1" LED zone 1 should now be off)
press * for saving the entry
# EXIT EXIT

For Output 2:
* 8 9713 24 # 4 # * 0 * (changing the default "2" LED zone 2 should now be off) # EXIT EXIT

For Output 3:
* 8 9713 24 # 8 # * 0 * # EXIT EXIT

For Output 4:
* 8 9713 24 # 12 # * 0 * # EXIT EXIT

By default all outputs are triggered for 10 seconds only.If you want the outputs to remain grounded as long as the event exists
(to follow the event) zeroes again need to be configured in Segment 3 of Locations 0 , 4 , 8 and 12.

For Output 1:
* 8 9713 24 # 0 # you are in Location 0, Segment 1
press * to step to Segment 2
press * to step to Segment 3
press 0 for your new entry (changing the default "10" -binary "1010" LEDs zones 4 and 2 should now be off)
press * for saving the entry
# EXIT EXIT

For Output 2:
* 8 9713 24 # 4 # * * 0 * # EXIT EXIT

For Output 3:
* 8 9713 24 # 8 # * * 0 * # EXIT EXIT

For Output 4:
* 8 9713 24 # 12 # * * 0 * # EXIT EXIT

So now you have configured the following:
When Block A (the same applies to block B ) is armed Output 1 is grounded. It will remain grounded until Block A is disarmed.
When an alarm is triggered Output 2 is grounded until a user inputs a correct code in Block A keypad and resets the alarm.
In AC Failure Output 3 is grounded until the AC is restored.
If Battery is low Output 4 is grounded until the battery is replaced.

Please give me some feedback if you understand the procedure so far ,so we can move on connecting the two receivers with the third Block C panel.

Some questions:
How do you want to arm/disarm and reset an alarm on  Block A (and Block B) ?
From the keypad or a keyswitch ?

A keyswitch must be connected to a zone. If shorted it arms the system. If opened it disarms and/or resets the system.

The custom mimic panel takes it's info from the two NX-508 ? Sorry, don't get want you are requesting.

The two NX-508 (of Block C ) will connect to the mimic panel driving  it's LEDs and Buzzers ?

The role of the Block C keypad ? Since by it's zone LEDs and keypad sounder it can do the job of the mimic panel.
Please define.

george

[ling_bin70]

Thanks for your Block A and B programing solution.

How do you want to arm/disarm and reset an alarm on  Block A (and Block B) ?
From the keypad or a keyswitch ? From the kaba keyswitch.

The two NX-508 (of Block C ) will connect to the mimic panel driving  it's LEDs and Buzzers ? yes

The role of the Block C keypad ? Since by it's zone LEDs and keypad sounder it can do the job of the mimic panel. For troubleshooting and  programing purpose

I have understanding the program, can I still bridge the COM, 1COM, 2COM, 3COM and 4COM NX-507 terminals with jumper wires together. Then connect a wire from any of these terminals to a ground terminal on the transmitter. I am using a dry contact which c/w  eight NC and eight NO points.

[ling_bin70]

The two NX-508 (of Block C ) will connect to the mimic panel driving  it's LEDs and Buzzers ? sorry only driving LED and the Buzzer is drive by NX-8 main board.

[fostiras]

Can you tell me the types of the transmitters/receivers?

[fostiras]

The two NX-508 (of Block C ) will connect to the mimic panel driving  it's LEDs and Buzzers ? sorry only driving LED and the Buzzer is drive by NX-8 main board.

OK.The NX-8 panel can drive two buzzers. It can drive another pair of buzzers if you add two relays.
Are you going to reset the buzzers with a keyswitch on Block C?

The reset is done by the keyswitch. Kindly take note that the setup of the equipment use is strictly requested by user. I need your assistance because not sure NX can meet their requirement especially the double reset. First to cut off buzzer at Block C and to distinguish the lighted LED after block A or C reset alarm.

[fostiras]

The ALARM LED BLOCK A and ALARM LED BLOCK B can be driven from the two NX-8 outputs (AUX3 and AUX4) without relay in a latched (as you mentioned) fashion. The zones of Block C (outputted from the two receivers into NX-8) should all be of 24 hour type. When one of the 4 zones is tripped (4 for the 4 events of Block A) the Output will latch and remain activated even if the event is cleared at the Block A side. The operator can reset the LED by a keyswitch. (arming and disarming the system - not with a single move). If the event still exists the LED will come ON again.

A solution of not having to short/open (arm/disarm) the keyswitch would be by installing a spring loaded keyswitch (like the ignition switch of a car) at the mimic panel with an NC contact on the resting position (always shorted=always armed). When a reset is required you put the key in and turn clockwise (opening/disarming) for a couple of seconds and release the switch back to it's default position (shorted). Although I have never tried this before I am almost sure it can be accomplished. Give me some time to check it out at work and I let you know for sure.

Also let me think a bit about the buzzer as well.

[ling_bin70]

Is the early programing for BLOCKS A & B NX-507 outputs configuration is still applicable?
How to programe this aux 3 and aux 4 via fiber optic transmition?

The three keyswitch install is momentary type.

What kind of configuration for the block C?

[fostiras]

Please find the spec for the fiber equipment.

Input Interface (OSD158T transmitter) Buffered and protected, open/closed sensing, contact closure from IN
to RTN will close alarm receiver N/O.

According to this yes the configuration for Blocks A and B I posted are fine. What is RTN? Is it return (ground)? I hope so!

The three keyswitch install is momentary type.

Momentary NC or NO?

How to programe this aux 3 and aux 4 via fiber optic transmition?
What kind of configuration for the block C?

Give me some time to check out the keyswitch behaviour for this mimic panel situation. Just to be sure. My plan would be to divide the Block C panel into two partitions. One partition giving an alarm to the LED and one partition to the buzzer. This way you can handle the two resets in a different manner.

george

[ling_bin70]

Momentary with NC and NO (sigle pole double throw).

Running out of time. Hope to hear from you soon.

[ling_bin70]

Hi George,

I need to disable the NX user code, default is 1234.

secondly, how to silent the exit sound from the keypad (tick.....). I have set the timing to zero sec.

Can I program the above using an LCD keypad?

Regards.

Ling

[fostiras]

Hi Ling,

I need to disable the NX user code, default is 1234.

Press * 5 1234 01 XXXX #   (1234=default master, 01=user 1 which is master,  XXXX=new master)
You can not disable it; just change it but be carefull not to misspress keys.

how to silent the exit sound from the keypad (tick.....). I have set the timing to zero sec.

Location 37, Segment 5, Option 6 (silent exit) should be off.
Press * 8 9713 0 # 37 # * * * *
LED zone 6 should be OFF. If not press 6 * to make it off.
# EXIT EXIT

Can I program the above using an LCD keypad?

It is easier .On the LCD you get the decimal numbers not the binary for numerical data.

george

[fostiras]

The keyswitch can be momentary NO or NC. The panel sees the change of state, a little less than 1 second press needed. It toggles between arm/disarm (reset).Zone type number 11 assigned to a zone.Just tested it on  an NX-8V2 panel.Give me some minutes for the rest (LED BUZZER).

george

[ling_bin70]

Thanks for your information, but in Location 37, Segment 5, Option 6 according to the NX manual is reserved.

From your early reply, dont really understand the connection. The COM, 1COM, 2COM, 3COM and 4COM NX-507 terminals with jumper wires together. Then connect a wire from any of these terminals to a ground terminal on the transmitter. Can the COM be indiviual instead of looping it? Any advantage? On the other end of the receiver must also jumper all the COM too.

Please advise.

Regards.

[fostiras]

Hi Ling,
1COM, 2COM ,3COM etc are the common contacts of the 3 contacts each relay has.They are not connected to any voltage or ground (that's why we call them dry contacts).
If you want positive control you connect all these terminals with 12 volt.
If you want negative control you connect all these terminals to ground (COM).
Then from the NO contact of each relay (1NO, 2NO, 3NO etc) you GET a GROUND (or a 12 volt for positive control) when activated.
You get a CADDX ground. For the transmitter this means nothing. The two system grounds need to be linked together so the transmitter can SEE the grounding when a relay is activated. I usually tend to link grounds together when two or more boards exist in a project so the whole thing has a solid reference.

If you want to connect two wires for each relay to the transmitter without linking the two system grounds, that is OK. Just more wires.But it's OK.

Exactly the same applies on the end side.

In a couple of minutes I will post you the rest of the connections.

george

[fostiras]

Hi Ling,
IT CAN BE DONE !
With only ONE keyswitch. When an alarm is triggered both LED and BUZZER get activated.
One keyswitch press deactivates the BUZZER ONLY.
The LED remains ON. If the alarm gets reset on BLOCK A side and reoccurs the BUZZER sounds again. The LED is still on.
One keyswitch press deactivates the BUZZER ONLY again. The alarm resets at Block A.
A second press on the keyswitch deactivates the LED too.
A new alarm activates LED and BUZZER again.

You need one zone to keep it always open so the Block C system gets never armed.
You need one zone to connect one keyswitch (NO or NC).
The buzzer is driven from the Bell output of Block C (you only need one Buzzer).
The LED can be driven from AUX1 output of Block C.
You need 8 zones (4+4) from the receiver to the Block C panel configured as 24 hour zones.

You need a total of 10 zones. You can get two additional zones from the NX-216 module or use zone doubling.
If you want two LEDs for each remote Block (A and B) you have to add some circuitry.
I tried partitioning the panel but it won't work.The keyswitch deactivates the LEDs together with the BUZZER.

Connections:
Connect the corresponding Block A, 4 receiver outputs to 4 Block C panel's zones.
Connect the correspondind Block B, 4 receiver outputs to 4 additional Block C panel's zones.
Connect them with a pair of wires for each zone as you want.
Do NOT use resistors (EOLs).
Keep ONE OPEN zone so the system never gets ready and armed by the keyswitch.
Connect the keyswitch to a zone without resistor.

Connect a 12volt BUZZER to the BELL+ and BELL- terminals. Connect a 3.3KOhms resistor across (in parallel) the BELL terminals.
Connect the LED's cathode in series to a 1KOhm resistor to the RLY1 NO output of the panel.
Connect a wire from the RLY1 C terminal to any COM panel's terminal.
Connect the LED's anode to the AUX+ terminal.

Configuration:
The 8 zones connected to the receivers should be configured as zone type 2 (24 Hour).
The always open zone should be configured as zone type 6 (instant).
The keyswitch zone should be configured as zone type 11 (Keyswitch).
Edit zone types 2, 6 and 11 with EOL DEFEAT feature (no resistors).

Configure the BELL output to system voltage.
Configure the AUX1 output with event 4 (24 hour alarm), Latched. (no other features).

All the above is tested and works.

Now whenever an event is triggered from Block A or B one or more zones are going to be grounded on Block C side triggering LED and BUZZER. If somebody wants to know what caused the alarm he can look at the Block C keypad. Or you can use one NX-508 to drive 8 LEDs, one for each of the 8 events individually. I have not tested if the LEDs will remain ON after a keyswitch press because I don't have an NX-508 right now.

Hope this helps you build your project.

george

[ling_bin70]

Hi George,

Thanks for your solution. Can you kindly provide the NX-508 output configuration on the mimic panel?

Waiting for receiving the good news on the last portion of your test.

The always open zone should be configured as zone type 6 (instant), All my zone are configure as type 2 accept zone 11 keyswitch zone.

Edit zone types 2, 6 and 11 with EOL DEFEAT feature (no resistors). No need to terminate the EOL resistor at each status zone (NX main board and NX-216)? How abt those spare zone?

Regards.

[fostiras]

Hi Ling,
let me first correct a mistake I made:
One of the 4 receiver outputs of each Block (A and B) must be directly connected to a LED of the mimic panel.That is event ARMED which is not an alarm but just status.So 2 LEDS in the mimic panel will show the ARMED status of Block A and Block B individually.The remaining 3 + 3 receiver outputs are connected as posted.

The permanent open zone should be configured as INSTANT. If configured as 24 Hour you will always have an alarm.

No need for EOLs if the EOL DEFEAT feature is enabled for the zone types used (2,6 and 11).
Spare zones need to be wire shorted and/or configured without belonging to ANY partition.This way they will not appear on the Block C keypad.

I have no NX-507/8 right now to test further. As posted before in opposite to the panel's outputs the NX-507/8 outputs can be configured to be activated if an alarm is triggered from a SPECIFIC zone.You can wire 6 loops from an NX-508 to 6 LEDs on the mimic panel (don't forget the 1 Kohms is series resistors). Configure all six outputs to be for event 4 (24 Hour alarm) and LATCHED like you did for the ALARM LED from AUX1 of the Block C panel. The extra thing is to configure each of the NX-508 outputs to one zone only.That is output 1 to zone 1, output 2 to zone 2...output 6 to zone 6. If one or more ALARMS occur the corresponding LEDs will come on and stay this way, only until the ALARMS are reset.If you try this out and the 6 LEDs behave like you want (not turning OFF after the first keyswitch press when you silence the BUZZER) there is no need for a General ALARM indication from AUX1 of the panel.If the LEDs turn off after the first keypress use the LED from AUX1 because I tested it and it works for sure for guaranteed ALARM acknowledge.

Locations 0,4,8,12,16 and 20 hold data for outputs 1 to 6 on the NX-508 always in 3 SEGMENTS.
Segment 1 = EVENT*** always a "4"
segment 2 = ZONE ***the extra setting from 1 to 6
Segment 3 = TIME *** always a "0"

The LATCHED feature is at:
LOCATION 1, Segment 1, Option 2  (should be ON = "1")  for output 1
LOCATION 5, Segment 1, Option 2  (should be ON = "1")  for output 2
LOCATION 9, Segment 1, Option 2  (should be ON = "1")  for output 3
LOCATION 13, Segment 1, Option 2  (should be ON = "1")  for output 4
LOCATION 17, Segment 1, Option 2  (should be ON = "1")  for output 5
LOCATION 21, Segment 1, Option 2  (should be ON = "1")  for output 6

I think that's about it.
Waiting for your feedback.

Hi George,

For the System Arm status, the cable from the receiver end would not be connect to a zone but connect to NX-508 said for example output 1 and com. It this correct?

Please advise.

Hi Ling,
let me first correct a mistake I made:
One of the 4 receiver outputs of each Block (A and B) must be DIRECTLY connected to a LED of the MIMIC panel.

From  the receivers to the MIMIC PANEL.

Hi George,
Can the start time said 0900hrs to set and test the dynamic battery test (on-load)?
Regards.

Schedules are for arm/disarm. What do you want exactly?

george

[ling_bin70]

sorry, what I meant is Can I set a specific schedule (time) to perform the backup battery test.

I dont get where to get the NO contact from the system arm status.

Regards.

[fostiras]

Hi George,
For the System Arm status, the cable from the receiver end would not be connect to a zone but connect to NX-508 said for example output 1 and com. It this correct?
Regards.

NO

NO = NO it is not correct

The ARMED status lines initially come from Blocks A and B. From the two NX-507 and then to the two transmitters.Then through the fiber to the receivers and from the receivers DIRECTLY to the mimic panel (one LED for Block A and one for B).

[fostiras]

"Dynamic Battery Test/Battery missing test – The NX-8 can be programmed to perform a Dynamic Battery Test for a selected duration the first time the panel is armed or disarmed every day. If the panel is not armed or disarmed during the day, it will perform the test at midnight.  The NX-8 can also be programmed to perform a missing battery test every 12 seconds."

"Dynamic Battery – The NX-8 can be programmed to perform a Dynamic Battery Test for this selected duration (1 to 255 minutes, 0 = no test) the first time the panel is armed or disarmed every day"

Location 37, Segment 2, Option 5   Battery missing test every 12 seconds
Location 40, Segment 1,               Dynamic Battery Test Duration (1 to 255 minutes, 0 = no test)

These are the only capabilities regarding battery tests for NX panels.

Thanks for your support. Hope to see the result of the double alarm reset working as I would be testing out soon.

Hi George,

There is a LED test switch on the mimic panel. May I know which data output event selection can be program?

Regards.

[fostiras]

I thought that the mimic panel was custom made. A LED test switch lights up all LEDs so the operator knows everything is OK. It has nothing to do with an arlarm event or status.All LEDs as posted are with negative control. You should wire extra wires from the cathodes of the LEDs through 1KOhms resistors to this LED TEST switch. Then this switch when activated will ground all LEDs together. The LEDs anodes are ALL connected to permanent positive (12 volt).

Have tried out the double reset of the alarm. When Block A or B trigger an alarm. It would send a contact signal to the mimic. The first condition work. (reset to clear buzzer), but the second condition fail. When the Block A or B reset the alarm, it would cut off the alarm LED. Any solution?

Can draw me a wiring diagram of the LED test switch. Cant get the result.

Regards.

The only reason the LEDs in Block C cut off while alarms are reset at Block A or B sites is the panel's output is not assigned with event number 4 (Tamper Alarm 24 Hour). This type of alarm even if restored (even on a disarmed system) still activates the output and can be seen on the keypad too. Only way to reset such a 24 Hour tamper alarm is with user code or keyswitch and having the initial cause of the alarm restored.

I told you it worked for me for A LED connected to the AUX1 output of the panel which will indicate an alarm situation from any zone on a disarmed system.
Also check the LATCHED feature of the output/s.

EVERY LED that is on your mimic panel has an anode and a cathode. To not be confused with the resistors connect EVERY anode to 1KOhms resistor. Then connect the other ends of the resistors TOGETHER and connect them to solid 12 volt positive.

Now when you ground a LED's cathode the LED lights up (no extra resistor needed here).These cathodes will be connected:
1. General alarm LED          :from AUX1 of Block C NX-8 panel
2. ARMED status of Block A : directly from the receiver output providing Block A alarms
3. ARMED status of Block B : directly from the second receiver output providing Block B alarms
4. ALARM in Block A           :from 1NO of NX-508 in Block C
5. AC fault in Block A          :from 2NO of NX-508 in Block C
6. BATTERY fault in Block A  :from 3NO of NX-508 in Block C
7. ALARM in Block B           :from 4NO of NX-508 in Block C
8. AC fault in Block B          :from 5NO of NX-508 in Block C
9. BATTERY fault in Block B  :from 6NO of NX-508 in Block C

I will show you how to connect 2 LEDS in the following diagram to the TEST switch:

           1NO --*------------|<LED<--------/\/\/\/\1KOhm/\/\/------*---++++12 volt
NX-508          |                                                                        |
           2NO ------*--------|<LED<--------/\/\/\/\1KOhm/\/\/------|
                    |    |
                    |    |----------->1N4148>|---------|*----------/TEST switch\----GND
                    |--------------->1N4148>|---------|

EVERY LED cathode is connected to the anode of a 1N4148 diode.ALL 1N4148 cathodes are connected to one pin of the switch.The other pin of the switch is permanently grounded.This way the switch can ground (light up) ALL LEDS together but if an output grounds one LED the diode does not permit the lighting of other LEDS.Use these connections for ALL the LEDs.

I thing this helps.Waiting for your feedback.
Are Blocks A and B OK? Do the alarms come OK on the two receivers in Block C? Can you see the alarms as open zones in Block C keypad?

Regards

Hi George,

Instead of a mimic panel, can I connect another keypad at the remote block C (only keypad nothing else) to monitor the block A and block B status?

[fostiras]

....the Block C keypad ? Since by it's zone LEDs and keypad sounder it can do the job of the mimic panel.

Of course a LED keypad can do the mimic panel job nicely.
Each Led will represent a status or alarm state of Blocks A and B.
The keypad sounder can only be silenced by a user code.

Give me some feedback on how the project looks like so far.
Are Blocks A and B ready ? Is everything connected in Block C?

Hi George,

I have configure output 2 with event number 5 BURGLARY siren for block A and block B respective. For the mimic panel at block C, I have program as data 4 zone tamper as mentioned in our previous mail (LED as Alarm). When Block A or block B trigger an alarm, the mimic panel at block C alarm LED did not lighted up but the buzzer sounded.

I have tried to change the program data to 42 any zone faulted, it works when an alarm trigger at block A or block B. The mimic panel at block C alarm LED lighted. When I reset the mimic panel the buzzer cut off and alarm LED lighted, but when block A or block B reset the alarm then block C alarm LED would be turn off.

How can I configure the block C mimic panel alarm LED when a second reset is done before it cut off the lighted LED?

Regards.

[fostiras]

Configuration:
The 8 zones connected to the receivers should be configured as zone type 2 (24 Hour).
The always open zone should be configured as zone type 6 (instant).
The keyswitch zone should be configured as zone type 11 (Keyswitch).
Edit zone types 2, 6 and 11 with EOL DEFEAT feature (no resistors).

Configure the BELL output to system voltage.
Configure the AUX1 output with event 4 (24 hour alarm), Latched. (no other features).

All the above is tested and works.

george

The 8 zones coming from the two receivers MUST be zone type 2!!!
The 4 is for the event of the output relay.
If a zone is assigned as 2 (24hour) it triggers an alarm even if disarmed. Also if the zone is closed again (the alarm from Block a or B is reset) it still shows a tamper error. The tamper error can only be reset with code entry on the keypad or the keyswitch. If the zone is still open (block A or B alarm is not reset) the Led will still light up. Remember I told you that Block C needs to be ALWAYS disarmed. For this one zone has to ALWAYS be open so that using the keyswitch for reset functions the panel will not arm. If you don't use my method and configure the zones in an other way then the operator should always keep the C panel armed. If something happens and he resets the buzzer with the keyswitch the panel will disarm and he has to arm the system again.This has no real security in it.
I know what you want to do exactly and it's very secure. In an alarm event only operators with keys can reset the alarms. The Led must stay ON as an alarm memory. It can only be reset if the real A or B alarm is reset. The way I am describing through these posts gives you EXACTLY the solution you want. Just follow my instructions carefully and try to reply sooner as I forget when you ask something after one or two weeks what this is all about.

Your led did not light up at Block C because a TAMPER event never occurred at the panel. That's because you have NOT configured the zone as zone type 2!

Please follow my advise carefully line by line as it is tested on my bench and works !

Hi George,

The 8 zones coming from the two receivers MUST be zone type 2. (I have configure all zone as 24 hour audible in block C mimic panel and shorted with a EOL resistor for unused zone and programe key switch as zone type 11).

Configure the AUX1 output with event 4 (24 hour alarm), Latched. (Where should I programe this output Aux1, Block A, Block B or Block C)?

Is your event 4 refer to zone tamper?

Lastly, the key switch zone which I have programe always lighted up on the LED keypad when an alarm trigger. I have shorted across a 3.3K resistor but fault persisted. Please advise.

Regards.

Hi George,

Sorry, for block A and Block B , is the previous configuration for event number 7 any siren or event number 5 burglary siren still applicable for alarm status LED?

Regards.

[fostiras]

The alarm status LED has not enything to do with BLOCKS A and B. A and B only provide ARMED status, ALARM, AC loss and low Battery to Block C. For the ALARM they provide to Block C, yes it's event 7 (any alarm).

Hi Ling,
The BLOCKS A and B are ordinary alarm panels giving their alarms and armed status through the fiber. The 3 + 3 (from both A and B) alarms become the zones of BLOCK C and the 1 + 1 Armed status (from both A and B) drive directly two LEDs on the mimic panel. I assume that all the above is functioning well so we do not have to mention BLOCKS A and B again.

Now BLOCK C is not used as an ordinary alarm unit (triggering alarms,sirens etc) it is just for driving LEDs on the mimic panel. It is just an input/output device so that the operator only has to hear a buzzer, monitor the LEDs and silence/acknowledge alarms of BLOCKS A and B. If the zone keypad LED lights up on the keypad for the keyswitch what difference does it make ??
The operator has to deal with the mimic panel!
BLOCK C simply operates as 24 hour TAMPER supervision. As an alarm is triggered in A or B a TAMPER situation exist in BLOCK C lighting up the corresponding mimic panel LED.
AUX1 output of BLOCK C gives the general ALARM situation stating that an ALARM exists at BLOCK A or B or both!
AUX1 drives the GENERAL ALARM LED with event 4. This LED is the only LED that will not turn OFF until alarm or alarms are reset in both BLOCKS A and B. It is the most important LED. After the operator has seen THIS LED then he will go on tracing down the Alarm by monitoring the other LEDs.
It is all here posted above.
Event 4 means the output will trigger as soon as a 24 hour zone (which is also called a TAMPER zone with zone type 2) is being faulted. The output will remain activated as soon as the zone is closed again and the TAMPER alarm acknowledged (keyswitch or user code).

Dear Ling,
you make me repost the same things all over again. You don't follow my advise presice like with the EOL defeat configuration. Please start over from the beginning of this guide of mine and try to follow EVERYTHING step by step. It's all in here. You do not ask me new stuff.
Then you do not give me real feed back of some sort like:
I don't know if BLOCKS A and B are finished?
The LED test ...does it work?
The mimic panel ? Is it ready?
Please help me and yourself as to finish this project of yours successfully.
And it's a good project I might add!

Hi George,

I'm sorry that I have made you repeat the same old thing again cos I have encounter problem in this project. Block A, block B and block C all equipment has been in operation.

Block A and Block B when there is an alarm the signal would send back to block C. Alarm sounded and LED lighted. Step 1, reset alarm buzzer cut off. Step 2, when block A or block B reset alarm the LED on the block C panel would cut off the LED which user need to reset before the alarm LED cut off. I have fail this step 2.

I have missed out the Aux step which I am not sure where to programe earlier.

I have a tamper LED on Block C Mimic can advise which event to program. User want this tamper LED to latch too.

Regards.

[ling_bin70]

I don't know if BLOCKS A and B are finished? Completed
The LED test ...does it work? Its works except for the alarm LED  cut off when 1st reset. No latching.
The mimic panel ? Is it ready? Ready.

To confirm, I just have to program the Aux 1 only not cable connection? Cos I have only one Alarm LED. (Any Alarm).

[fostiras]

Hi Ling,
I am very glad to hear about the finished parts of your project.

The keypad zone LEDs of BLOCK C WILL cut OFF when the alarms in A&B are reset.
The keypad zone LEDs display the input status of zones and follow whatever comes in.They can not be latched in anyway. That is why we use our programmable outputs. Two things are needed so that the general alarm LED will function as desired.

1. The 6 (3+3 A&B) zones of BLOCK C need to be zone type 2 (24hour or Tamper zones).
2. The AUX 1 output needs to trigger on a tamper event (4) and latch (not follow the event).

Tamper events NEVER clear unless a valid code is entered (or a keyswitch is activated).
Even more some security companies configure the system in a way the user can not clear tamper events on his own with his code and only the security company can acknowledge the tamper events and clear them remotely. I am saying this to show you that in many cases it is difficult to clear tamper events not the opposite like in your case. One is sure though: The keypad LEDs FOLLOW the status of the inputs. If A&B alarms are reset the LEDs will be OFF, but the tamper event will latch the output and your mimic panel general alarm LED will still be ON until BOTH the alarms are reset and the user activates the keyswitch; always being sure that alarms have been acknowledged and recorded. And ALL the above happens in an even disarmed panel state. Because the panel can not give you a trigger from a specific zone but it's a common trigger from any zone I posted that you could connect additional 6 LEDs from the outputs of the NX-508. These outputs can be configured as AUX 1 (event 4 ,latched) but additionally they can be assigned to ONLY ONE specific zone, showing the kind of alarm that occurred. So the operator has a GENERAL ALARM LED and the specific LED which will show the kind of alarm.

I told you that the keypad can do much of this job but not as clear and efficient as the mimic panel; thats what a mimic panel is all about so you don't have to train people how to use and interpret the keypads indications.

All you have to do is read carefully and follow step by step the final connections of LEDs from the BLOCK C AUX 1 and BLOCK C NX-508 outputs.

 

EVERY LED that is on your mimic panel has an anode and a cathode. To not be confused with the resistors connect EVERY anode to 1KOhms resistor. Then connect the other ends of the resistors TOGETHER and connect them to solid 12 volt positive.

Now when you ground a LED's cathode the LED lights up (no extra resistor needed here).These cathodes will be connected:
1. General alarm LED          :from AUX1 of Block C NX-8 panel
2. ARMED status of Block A : directly from the receiver output providing Block A alarms
3. ARMED status of Block B : directly from the second receiver output providing Block B alarms
4. ALARM in Block A           :from 1NO of NX-508 in Block C
5. AC fault in Block A          :from 2NO of NX-508 in Block C
6. BATTERY fault in Block A  :from 3NO of NX-508 in Block C
7. ALARM in Block B           :from 4NO of NX-508 in Block C
8. AC fault in Block B          :from 5NO of NX-508 in Block C
9. BATTERY fault in Block B  :from 6NO of NX-508 in Block C

Waiting for your feedback. This project of yours MUST complete successfully.
