Consult the factory regarding custom sizes, products, options or special requirements.
Normal operation is with the panel switches in the “AUTO” position. When the switch is placed in the “ON”
position, the appropriate fan-start relay will be energized. The relay contact will activate the fan. An auxillary
contact will send a signal back to the annunciator as positive indication that the function occurred. When the
switch is placed in the “OFF” position, the corresponding fan-disconnect relay will be energized. The relay
contact will interrupt the automatic fan-start signal from the fire control system.
The FSCS does not control the Smoke Evacuation fans directly. It is the FACP that provides the outputs that
control the fans and lights the Status indicators. Connections from the FSCS to the FACP are through conduit,
20’ or less in length. The switches and the LED indicators in the FSCS are wired to UL Listed terminal blocks
and from the terminal blocks directly to the Fire Control Product outputs.
