Systems that are not maintained usually lose all power, including their battery backup during a power cut. When this happens, the external sounder will activate using its own backup battery to indicate there is an issue, but this also indicates that the system has not been correctly looked after.
A non-maintained intruder alarm could suggest a few things such as:
1. Poor performance of the system
2. Not insurance approved
3. Likely that the system is not used very often
4. Not monitored for Police response
Just like your boiler or your car, it is important to make sure your alarm is maintained every year to ensure it operates correctly and is reliable.
