The ELK-965 is a Low Battery Cutoff Module combined with a Master Power Switch. It is designed to work with virtually any 12 Volt control panel or power supply.

In the event of an extended power outage, the ELK-965 sensing circuit automatically disconnects the battery when the voltage falls below 10 Volts DC. This helps to prevent "deep discharging" of the battery. The convenient power switch permits the installer or user to easily disconnect both the Battery and the AC power from the control or power supply.

Also available is the ELK-964B20 (Master Power Switch Only version) which is the same as an ELK-965 but without the Low Battery Cutoff circuitry.
