FCI FC-72 Series, Instructions & Operating Manual

Page: 22 / 32

19.0 STAND-BY BATTERY CONNECTIONS
These (non-power limited) terminals are for the connection of sealed lead calcium (gel type) rechargeable
batteries. BE SURE TO OBSERVE POLARITY. Terminal 43 is positive (+) and 44 is negative ( - ). The
automatic float charge circuitry is capable of maintaining batteries with capacity ratings between 1.9 and
17 ampere/hours. The maximum charge rate is limited to 0.9 amperes.
If the batteries are connected in reverse, the panel protection circuitry will immediately cause the 6 ampere
battery fuse to open.
Stand-by Requirements - To determine the size of standby batteries, you must first determine how much
current will be drawn in the standby mode. Refer to the Battery Standby Calculation Chart, Table 2.
20.0 POWER SUPPLY
The output of this power supply is 24 VDC at 4 amperes and complies with U.L. Standard 864.
The transformer secondary is fused at 6 amperes. Connect the power supply to a 120 VAC source.
This connection must be to a dedicated branch circuit and mechanically protected. All means of disconnecting
the circuit must be clearly marked “FIRE ALARM CIRCUIT CONTROL” and accessible only to authorized
personnel. Fusing of this circuit must comply with local codes for over current protection, and/or Article 760 —
“Fire Protective Signaling Systems” of the National Electric Code, NFPA 70.
The transfer relay will automatically transfer the system to the stand-by batteries upon reduction to 85% or
total loss of AC power.
21.0 FUSES
The standby battery circuit is fused as shown. A 5 amp. permanent fuse (F7) serves as main power limiter
in the BMFC and a 6 amp. fuse on the PS-6 protects the power supply.
22.0 LOCATING A TROUBLE
All vital circuits of the FC-72 have an associated yellow “TROUBLE” LED which will identify the circuit
in trouble. Refer to the appropriate section of this m manual for further instructions.
The following problems will cause a common System Trouble condition, but will not be indicated individually.
TROUBLE CIRCUIT COMPONENTS
If the failure of a component associated with the trouble circuits should occur, and field repairs are not possi-
ble, all initiating and notification appliance circuits will continue to function, but THERE WILL BE NO ELECTRI-
CAL SUPERVISION DURING THIS PERIOD.
ZONE DETECTOR MODULES
Should a failure occur, a spare module may be used, or if additional zones are in use you may remove the
EOL resistor from the faulty zones’ wiring and temporarily connect the zone wiring in parallel with a known good
zone. Once you have removed the zone module from its connector, a System Trouble will occur.
Connecting J9, J-10 to the RIGHT of the missing module will clear the trouble but will not supervise any
further zones.
NOTIFICATION APPLIANCE CIRCUIT MODULES
Failure of one of these modules will result in loss of supervision on both notification appliance circuits. Both
circuits will still operate with the module removed, as will the Polarity Reversal output and the City Box output.
If using BMC-6, Jumper J-11 must be in place.
The Main Power Limiter on BMFC-6 is independently fused by permanent fuse F7, 5 amp., Type 2AG.
Power supply Check 120 VAC input. Check fuse on PS-6. Check green AC LED. Check all fuses.
Check for 24-26 VDC across voltmeter terminals on power supply.
Module unplugged Replace the missing module or install J10A, J10B after last active zone.
Remote trouble Connect a jumper between Terminals 17 and 19. If the trouble clears,
check the RTI and associated wiring.
Supervisory signal Disconnect the wiring on the transmitter or Terminals 3, 4, 5, and connect
a 220 ohm, 5 watt resistors between 3-4, 4-5. If trouble clears, check the lines
for an open circuit.
Transfer relay coil open Check for open.
