All professionally installed alarm systems include a back-up battery in the main alarm panel. This battery provides power to the alarm in the case of a power cut. Alarm Back-up batteries are normally 12V, and can be 2.1ah, 3.4ah or 7.1ah. Please note, all battery types are compatible with each other – for example, you can swap a 2.1ah with a 7.1ah (as long as there’s enough physical space).

How often should you change a wireless alarm sensor battery?
If you have a system with wireless sensors, all of these will have a small battery in them. A wireless sensor battery should be changed every 12 to 24 months, depending on how active the sensor is.
Please note, for energy saving purposes wireless sensors are only active when the alarm system is ‘armed’ – hence why the red light won’t actively flash when you walk around your property.
