General Description
The Fan Status and Control Annunciator, FS-Series, is designed for use in high-rise buildings and other facilities that must have a means to manually control the fans or dampers designated for smoke removal during a
fire emergency. The unit is designed to work in conjunction with fire alarm and control systems to provide
visual status and manual control capability for each smoke removal fan.
A three position switch is provided for each fan, along with two status indicators. There “ON/OFF” indicators
are activated by contacts on the fan starter relays. The “ON” indicator will light only when the fan is running. The
“OFF” indicator will light whenever the fan is NOT running.
When the switches are in the “AUTO” position, the system fans will be monitored only. During a fire emergency,
the fire alarm system will operate the fans as per the smoke removal system design. Should conditions
warrant manual control, and at the command of the authority having jurisdiction, the annunciator can be used
to provide specific control of each smoke removal fan.

CONTROL
Operation
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.
