Wiring: Fire signal relay (E series)
Electrical Installation (cont.)
A contact closure across digital input terminals MI3 and DCM
will result in fan shutdown. 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.
From main FACP or
NAC box (if applicable)
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.
From main FACP or
NAC box (if applicable)
An alarm condition will stop the
fan and issue an “EF,” External
Fault, at the fan controller’s wall
controller.
