a) Operation of the audible and/or visual devices that are connected into the indicating appliance circuit.
b) Operation of the red alarm LED.
c) Transfer of the auxiliary alarm relay contacts.
d) The polarity of the voltage on the releasing circuit will reverse after 5 or 45 seconds (Dry Contact Circuit fixed at .5
seconds) for a period of approximately 90 seconds or continuous.
e) Sound local buzzer if selected.
SUPERVISORY CONDITION
Operation of a device that is connected into the supervisory circuit will cause the yellow supervisory indicator to come on and will
also cause a system trouble condition (see “System Trouble Indications”).
TROUBLE CONDITIONS
CAUTION: With the exception of the loss of the AC-ON LED and transfer of the auxiliary trouble relay contacts, none of the
trouble indicators will operate on loss of AC power unless an adequately charged battery is properly connected.
Following are the conditions that will result in a system trouble:
1) A decrease in the current in the initiating device circuit to approximately 3 mA.
2) An increase in the current to approximately 10 mA or a decrease to approximately 2.0 mA in the indicating appliance
circuit.
3) A decrease in the current in the supervisory circuit to approximately 2.0 mA or activation of a supervisory device.
4) Loss of or a decrease of battery voltage to approximately 23 Volts.
5) A ground fault on any circuit.
6) Loss of, or reduction of AC input voltage to approximately 80 Volts.
7) Loss of auxiliary power at terminals 3 or 5.
8) An increase in the current to approximately 10 mA or a decrease to approximately 2.0 mA in the releasing device circuit.
9) Operation of the “Releasing Circuit Disable” switch to the disable position.
10) Connecting an indicating appliance backwards
SYSTEM TROUBLE INDICATIONS
CAUTION: A problem in an audible or visual device may not be apparent when the panel is in a normal condition. If a trouble
condition is indicated when the panel is in the alarm condition the problem must be located and corrected.
A system trouble condition will result in the following:
1) Operation of the built in trouble buzzer.
2) Operation of yellow trouble indicator.
3) Transfer of the auxiliary trouble relay contacts.
The panel will restore automatically to a normal condition when all trouble conditions are cleared.
NOTE: If the initiating device circuit is programmed for Style D (Class A) and the circuit has been opened for several seconds,
the reset switch must be operated to clear the trouble condition.

TO SILENCE AN ALARM OR TROUBLE CONDITION
To silence an alarm or trouble condition operate the silence switch to the silence position then release the switch.
CAUTION: Do not silence an alarm condition without investigating and determining that an emergency condition does not exist.
Silencing an alarm condition will restore all the devices that are connected to the indicating device circuit but will not restore the
auxiliary alarm relay contacts. The red alarm LED will remain on and the yellow silence LED will turn on.
Silencing a trouble condition will silence the built in buzzer and turn on the yellow silence LED. The yellow trouble LED will
remain on. The trouble relay contacts will restore to normal if selected. The panel will restore automatically to a normal condition
when all trouble conditions are cleared.
NOTE: If the initiation device circuit is programmed for Style D (Class A) and the circuit has been opened for several seconds,
the reset switch must be operated to clear the trouble condition.
TO RESET AN ALARM CONDITION (INITIATING CIRCUIT PROGRAM FOR STYLE D (CLASS A))
Determine the cause of the alarm condition and if necessary remove the cause. Operate the reset switch to the reset position, then
release the switch. The trouble buzzer and LED will come on when the switch is in the reset position. When the switch is released
the buzzer and LED will restore to normal if there are no existing trouble conditions. They will remain on if a trouble condition
exists.

INSTALLATION
Please read entire manual before attempting installation of this panel.
CAUTION: This panel should be installed and maintained in accordance with Section 760 (Fire Protection Signaling Systems)
and all other applicable sections of the National Electrical Code, all applicable NFPA Codes and Standards and the
authority having jurisdiction.
The unit should be installed in a dry location, approximately 5 ft. from the floor where it will be conveniently accessible for testing
and servicing.
The main circuit board module may be removed to ease installation.
CAUTION: If not connecting the solenoid at this time, do not install the diode/resistor assembly across terminals 21 and 22,
install a 5.1K resistor only. The diode/resistor assembly must only be installed IN SERIES with the solenoid.
Install all required conduits, external wiring and devices and make all connections that are external to the panel.
With the AC power turned off at the circuit breaker panel, connect the 120VAC hot, neutral and ground as shown on the connec-
tion drawing. Turn the AC power on and connect the battery leads. The green LED should be on, all other indicators should be
off. If the battery is not fully charged a trouble condition may appear for some period of time. It is recommended that the battery
be charged for 24 hours before placing the system in service.
Taking one circuit at a time, remove the 5.1K resistor from the panel, connect the circuit wires to the panel and place the correct
device across the circuit at the end of the line as shown on the connection drawing. If the initiating device circuit is connected as
a Style D (Class A) circuit connect end of line resistor as shown. Verify that the panel restores to a normal, after wiring for each
circuit is complete. When the initiating device circuit is connected to the panel it will be necessary to operate the reset switch to
extinguish the trouble indicator.
INSTALLATION OF BEZEL FOR SEMI-FLUSH INSTALLATIONS.
For semi-flush installations mount the housing so that the front edge protrudes 1" from the finished wall surface. After all conduits
and wiring are in place and the wall surface is completely finished, slide the trim bezel in place and fasten with 4 #6-32 x 1/4"
machine screws and nuts.

PFC-100RC • 5403524-REV M • 3/03
CIRCUIT BREAKERS
There are two circuit breakers in this panel, one for the primary (AC) power and one for the secondary (battery) power. If either
of these breakers trip a system trouble will occur. If the AC breaker trips the green AC-ON LED will be extinguished.
If the secondary power breaker trips, diagnostic LED DS 1 will come on, indicating low or missing battery.
RESETTING CIRCUIT BREAKERS
The circuit breakers for AC power (CB2, located lower left of panel) and battery power (CB1, located upper left of panel) reset
when the white button, located in the center of the circuit breakers, is pressed. See illustration on page 14.
The electronic circuit breakers for the indicating and releasing circuit reset when the momentary switch (SW1, located upper left
of panel) is pressed. A system trouble will be generated and DS11 will light. DS10 and/or DS13 will be off. See illustration on
page 14.
INACTIVE CIRCUITS
All inactive alarm and supervisory initiating device circuits and indicating appliance circuits must have the end-of-line resistor
installed on the panel terminals. On circuits that have four terminals, this resistor must be on the outside two terminals.
BATTERY REQUIREMENTS
This panel requires a 24 volt gel-cell battery for proper operation. 24 hours of standby power is required for Extinguishing System
Release. 90 hours of standby power is required on FM Approved deluge - Preaction Sprinkler System Release.
