Alarm System Batteries

All correctly designed and installed systems require a back-up battery to maintain the system in the event of a mains power failure. All modern control panels use 12v rechargeable sealed lead/acid batteries. The battery will supply power to the control panel, powered detectors (PIRs etc) and will 'Hold' the external sounder off - in modern systems the external sounder will sound if power from the control panel is removed.

Under non-alarm conditions a back-up battery will maintain the system for several hours (load and battery capacity and battery condition dependent).

Which Battery?

In general the largest capacity batter that will fit in the control panel is the battery of choice. Compact control panels like the ADE Optima Compact G3, the ADE Accenta Mini, the Texecom Veritas 8 Compact, the Pyronix Sterling Compact and the Scantronic 9448 will only accept 2.1Ah batteries. Full size control panels and blank end-stations will accept any battery up to 7.0Ah. The table below gives the dimensions of commonly used batteries.
