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.
