Inspecting Batteries
Inspect the standby-batteries annually to determine the connection integrity to The Sigma A-CP Fire
Control Panel. The fire control panel contains sealed lead acid batteries to provide standby power in
the event of mains failure. The standby-batteries have a life expectancy of 3 to 5 years. Test the
standby-batteries annually in accordance with the battery manufacturer’s recommendations to
determine their suitability for continued standby operation.
Replacing Standby-Batteries
Replace standby-batteries when the service period reaches 3 to 5 years or when the low-battery
indicator illuminates on the power supply. Specify replacement batteries that are Power Sonic model
PS-1270 F2, sealed-lead-acid, 12 VDC and 7 AH or 12 AH.
