Batteries for Alarm Systems
In general alarm systems use batteries in two parts of the system if it’s a wired alarm, and three parts if it’s a wireless alarm:
- Alarm panel battery: this is the battery that powers the main alarm system and is the most important battery in your alarm.
- Alarm bell-box battery: if you have a live ‘sounder’ outside your property, this will have a ‘backup battery’.
- Alarm sensor battery: if you have wireless sensors, each sensor will have a battery which will need to change every 18 to 24 months
With the ‘traditional’ (i.e. not new ‘smart’ alarms), there is a high likelihood that the system uses a 12v battery – probably a 2.1aH, 3.4aH or 7aH. The alarm batteries in the panel act as a vital backup in case there is a loss of mains power. If fully charged and in working order, a panel battery can keep your alarm working for up to 12 hours without mains power. An Alarm Panel battery should last about four to five years with normal usage patterns.
