1.0 FUNCTIONAL SWITCHES
1.1 BMFC Switches
Operational switches located on the BMFC basic fire card are as follows:
•
Trouble Silence Switch (Fig. 1) This switch, when operated, will silence the System Trouble audible
sounder. Upon correction of the trouble condition, the audible will sound again to indicate that the switch
should be returned to the normal position.
•
Battery/Bell Test Switch (Fig. 1) This switch, when operated, de-energizes the Transfer Relay disconnect-
ing the power supply from the panel circuitry. It also energizes the alarm relay operating all local
notification appliances from the stand-by batteries. Operating this switch will not reverse telephone lines
or activate the city box output.
•
Lamp Test Switch (Fig. 1) This switch, when operated, will light all red LED alarm indicators, all yellow LED
trouble indicators on zone modules, and all Remote Zone Annunciators (RZAs). All alarm indicators are
supervised.
•
Reset Switch (Fig. 1) This switch, when operated, resets all zones from the alarm condition, as well as
interrupting the Smoke Detector Power Output to reset the detectors. It will also cause all the yellow LED
zone trouble indicators to light.
•
City Box Disconnect Switch (Fig. 1) This switch, when operated, will disable the City Box Output and/or
Polarity Reversal Output (JRR must be cut for Polarity Reversal disabling). The yellow LED above the
switch will light, and a System Trouble will occur when the switch is in the OFF position, or when the
control is in the alarm mode. The yellow LED will remain lit until the master box and the control are reset.
1.2 Zone Module Switches
Operational switches mounted on the zone modules are as follows:
•
Zone Maintenance Switch - Each zone has a maintenance switch. Operation of this switch will disconnect
the zone alarm output. This will also cause both a System and a Zone Trouble. Other zones are not affected
by the operation of any one zone maintenance switch.
2.0 GROUND FAULT DETECTION
External wiring leaving the FC-72 is supervised for
ground faults. When a ground is present on the exter-
nal wiring the yellow “GROUND FAULT” LED will light
and a System Trouble will occur. Separate positive
(LED 4) and negative (LED 5) indicators are provided
to determine the type of ground fault present. This will
help when trouble shooting. To locate the source of
the ground fault, remove each external wire from the
FC-72 one at a time, then connect a voltmeter to Ter-
minals 24 and 30. Normal voltage should be from 5.5
to 6.5 VDC. If not, check the field wiring.
3.0 SHORT CIRCUIT DETECTION
The notification appliance circuit wiring Terminals (6-13) are supervised for short circuits across either
notification appliance circuit. When a short circuit is present the yellow “SHORT CIRCUIT” LED will light, and
a System Trouble will occur. See Section 7.

NOTE: Terminal 24 of the FC-72 must be connected
to an earth ground per Article 760 of the National
Electrical Code. Conduit ground is not acceptable.
Failure to make this connection will result in a
reduction in lightning protection.
