Alarm Battery

Batteries can be used to power wireless alarm devices or security system control panels as backup power sources or primary sources. Lithium batteries generally last longer than traditional alkaline alarm batteries.

Backup Alarm Battery

In the event that a device loses connection to electricity, a back-up alarm battery ensures that a security system will continue to work after losing AC power. Back-up alarm batteries typically power a system for a 24-hour period.
