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
The FACP must have a feature that allows the disabling of the control panel battery charger.
