Burglar alarms

An Alarm battery provides power to a system when the primary source of power is unavailable. Alarm battery ranges from人2 small single cells to retain clock time and date in computers, up to large battery room facilities that power uninterruptible power supply systems for large data centers. Small backup batteries may be primary cells; rechargeable backup batteries are kept charged by the prime power supply.

Backup batteries are almost always used in burglar alarms. The backup alarm battery prevents the burglar from disabling the alarm by turning off power to the building. Additionally these batteries power the remote cellular phone systems that thwart phone line snipping as well. The backup battery usually has a lifespan of 3-10 years depending on the make and model, and so if the battery runs flat, there is only one main source of power to the whole system which is the mains power.

Should this fail as well (for example, a power cut), it usually triggers a third backup battery located in the bell boxes on the outside of the house which simply triggers the bell or siren. This however means that the alarm cannot be stopped in any way apart from physically going outside to the bell box and disabling the siren. It is also why if there is a power outage in the area, most burglar alarms do start ringing and cannot be realistically stopped until the main power is restored.
