Electrical Installation (cont.)
Wiring: Fire signal relay (M series)
A contact closure across digital input terminals M3 and GND will
result in fan shut down. The relay uses a Normally Open (N.O.)
contact as shown. The relay coil must be energized by the
FACP for fan shutdown.
Two additional relay coil leads are provided to facilitate
supervision pass-through where required.
Optionally, the relay can be used with a Normally Closed (N.C.)
contact as shown. The relay coil must remain energized by the
FACP for fan operation. This would be considered a fail safe or
fail open wiring arrangement.
Two additional relay coil leads are provided to facilitate
supervision pass-through where required.
An alarm condition will stop the
fan and issue an “EF,” External
Fault, at the fan controller’s wall
controller.
