Page 7: Introduction To The Charger
1. Introduction to the Charger Overview The CHG-120 battery charger is designed to charge lead-acid batteries that provide emergency standby power for a Fire Alarm Control Panel (FACP). Two 12-volt batteries are always used in series to supply 24 VDC nominal. The following list gives answers to... -
Page 8: Specifications
Replacing Batteries Only replace batteries with the same charge rate and capacity as other batteries in the set. For example, if replacing one of four 60 AH batteries, make sure the replacement battery has the same charge rate and capacity as the other three batteries.
