1.7.3 CHG-120F Battery Charger
The CHG-120F is capable of charging 25 AH to 120 AH lead-acid batteries with the newer version of the MS-9200
main circuit board which allows disabling of the FACP battery charger. The batteries and charger can be housed in
the Fire•Lite BB-55F Battery Box which can be mounted up to 20 feet away from the control panel. Note that when
using the BB-55F for housing the charger and batteries, a maximum 25 AH battery can be accommodated. For larger
Amp Hour batteries, use multiple BB-55Fs. Refer to the CHG-120F Manual for additional information.
!
WARNING: Do not apply AC power or batteries until the system is completely wired and ready for testing.
Set the CHG-120F Voltage Select switch (SW1) to match the AC power source voltage (120VAC or 240 VAC). With
the breaker at the main power distribution panel turned off, connect AC power wires to CHG-120F TB1 as shown
below.
Wire the CHG-120F to the MS-9200 as shown. Cut Jumper JP1 on the newer versions of the MS-9200 main circuit
board to disable the FACP battery charger when using the CHG-120F. Wire the batteries to the CHG-120F but do not
connect the Battery Interconnect cable until the system is ready for testing.
