INFORMATION:
Other batteries for a range of alarm manufacturers are available, please see our other listings. These batteries should be replaced every 3 years to ensure your alarm has enough battery power to sound the alarm in the event of a power cut. If your control panel is beeping, it could mean a new battery is required. A flat battery will cause an alarm to sound.
