FSCS series graphic
annunciator
Description
The FSCS series graphic annunciator provides detailed
information on the location of dampers, barriers, and
fans. The graphic annunciator may display a single
smoke zone, a floor, or an entire building. Panel control
functions, tailored to firefighter smoke control needs,
include the actual status of smoke control equipment
and components, which are capable of activation. LED
confirmation of individual fans sensed by pressure
difference and indications of damper position can be
designed into the graphic annunciator, the companion
LCD display, and the LED switches. The FSCS series
graphic annunciator receives its power from the VM-1
network.

Fan control and monitor
circuit
Figure 23 on page 38 shows a typical fan control and
monitor circuit. During normal operation, the fan (item 1)
is off and may be turned on by either the HVAC system
or by the automatic fire detection system. During alarm
operation, the automatic fire detection system activates
the GSA-IO module (item 5), which energizes relay K1
and connects the line voltage to the fan.
The GSA-IO module (item 5) also monitors the air flow
switch (item 2) used to signal when the fan reaches the
required output capacity. The GSA-IO module activates
a Monitor event when the switch closes or a Trouble
event if the switch fails to close in the time allowed.
The GSA-IO module (item 6) monitors the air flow switch
(item 3) used to signal when the fan is not operating.
The GSA-IO module activates a Monitor event when the
switch closes or a Trouble event if the switch fails to
close in the time allowed.
The GSA-CT1 module monitors the end-of-line power
supervision relay (K2) and activates a Trouble event on
loss of 24 VDC.
Notes
•
Install relay K1 ahead of the HVAC system
controller.
•
The NFPA 72 Code requires that the wire distance
between control devices and air handling units
(AHUs) does not exceed 36 in. (91.44 cm).
•
24 VDC is from a regulated and filtered power
supply that is UL/ULC Listed for fire protective
signaling service.
