SMF - Just Installed!
You can only have one wireless receiver on a 20P.
You need a 16.5 volt transformer for the 20P. Honeywell 1321 16.5vac 25va
With all of those keypads and motion detectors you will need an auxiliary power supply.
I'm assuming the 6 motion detectors are hard wired because you can't mix manufacturers with wireless.
The siren gets it's power directly from the battery.
How far is the range? Will a transmitter on one floor reach the receiver/keypad on another at the opposite end of the house?how hard would it be to hook a light or two into the alarm, so that when the alarm went off, a few lights throughout the house turned on?
Any answers out there to the following:ELK-P624 - Power Supply & Battery Charger is this compatible with the vista 20p, can't find anything honeywell specificquestions remaining:How long will the panel run without power? How long does the 7AH battery last? can I wire multiple batteries in parallel for a longer operational time?Also: if the 20p has 48 max zones, 16 smoke and 16 x/10, do smokes/x10 count towards that? Or is it 48 +16 +16?
