NX-8 Second Siren and internal Siren

[petros82]

Hi, i have a NX-8

I already had install an external siren with success.
I like to install a second external siren and a internal siren too.

How can i do that?

I have a 12V relay with 6 pins. The internal siren have only (+) (-) terminals. The external Siren works with cont. possitive

Also when i press the Manual Fire Button the installed siren only flashed but not sound

Thanks!

The internal siren (peizo) is run off aux 2 which can supply 250mA. The second internal peizo can simply wire to the same aux 2 output.  The external siren o/p can either be a voltage o/p for a siren or a modulated o/p for a horn speaker. Its o/p is 500mA when set for voltage which will drive at least two sirens (generally speaking) or three horn speakers if 8^ or above.  IE  you don't really need a relay.

it really all depends on if you currently have speakers or sirens, there is a difference.  by default, the setting for the NX-8 provides an audio output for a speaker.  it makes the downward sweep tone for burglary and steady tone for fire.
