If the power fails at your premises, the alarm system will automatically switch to a rechargeable backup battery that is contained within the alarm panel. The touchscreens will show a power trouble condition and the analog keypads will show AC Loss. Once the power is restored, the internal battery will recharge in preparation for another power failure.
All batteries will have to be replaced every 3-5 years. A battery trouble condition may appear, but we also track the age of your battery to ensure you are within limits.
