I would like to integrate my door access device with conventional Fire panel. so kindly advise me below procedure can work or Not.
1, We have 5 Door access device, all the device get power supply from one location.so we planned to cut the all 5 devices 12V 3 amp DC power adapter -ve line and joined 5 cable as single cable and pass through fire alarm panel output relay (COM & NC) then split it in to 5 cable then connect to device.
2, Our Plan is to cut the power of the Door access device if fire alarm triggers.
