When using more than one Detector on a
single zone of a conventional FCP , it is
important to choose the correct method
of wiring. Incorrect wiring may result in a
Detector isolating subsequent devices on that
zone if it enters a Fault condition, and may
prevent these subsequent devices signalling a
Fire condition back to the FCP .
If the FCP monitors for point detector
removal, it is possible to use the following
wiring diagram which uses a diode to provide
zone continuity in the event of a Fault state on
any Detector.
Recommended diode type: Schottky, 60 Volt,
1 Amp, must be UL listed for installations
meeting NFPA72
