Battery and Power Selection

Alarm batteries help keep systems operational during a mains power failure. Lead-acid backup batteries should be checked regularly and replaced when they no longer hold sufficient charge. Wireless sensors may also require model-specific replacement batteries.

Power Requirements

Match the voltage, battery type, amp-hour rating and connector style to the original panel, sounder or device specification. Incorrect batteries or PSUs can reduce standby time or prevent the system operating correctly.
