#185382 - Monitor standby Loop Current
Responding to: Satish S Munot's previous message
The detector load current will be few hundred micro amps.
The panel has to always monitor the current(stand by current) on the loop.
by knowing the standby current if current above standby current it can be taken as logic1 or logic0.
Yes serial communication (not standard serial comm it is proprietary) between Smoke Detector and Fire control Panel.
