The CHG-75 battery charger is designed to charge lead acid batteries that provide emergency standby power for a Fire Alarm Control Panel (FACP) and related equipment. Two 12- volt batteries are used in series to supply a nominal 24 VDC. The battery charger is compatible with any FACP that uses lead-acid batteries with a rating of 25 AH (amp-hours) to 75 AH.
Diagnostic LEDs for monitoring: Primary AC On, Charger.
Ground fault detection circuit (can be disabled).
Charger can connect to the Signaling Line Circuit (SLC) of a Fire-Lite addressable intelligent control panel for trouble monitoring.
Mounts in a BB-26 or BB-55F enclosure.
Screw terminal connections for battery, battery backup to other equipment and SLC loop.
Form-C trouble relay rated for 2.0 A @ 30 VDC (resistive).
Battery, charger, and AC voltage supervision.
AC loss reporting delay option for 8- or 16-hour delay.
Connectors for trouble input and output direct CHG-75 troubles to FACP and allow daisy-chaining of external troubles through the charger without affecting charger operation.
Master trouble input allows monitoring of another device or zone.
