TO REPAIR AND SERVICE AN EXISTING INTRUDER ALARM.
South Walsham, NR13
I have an alarm installed but one or more of the detectors is making a squeeking noise at irregular intervals throughout the day and night. I would like to have the system checked and defective parts replaced.

We have a Challenge CEF AP28 burglar alarm installed.
We had a short power cut overnight last week. The alarm is used daily and was working fine until then. (The power has been restored to all parts of the house.)
The following morning the burglar alarm failed to "set". Normally you enter your 4 digit code on the control panel, the system beeps and you have 15 seconds to leave the house. Now you enter the code, but nothing happens after that.
The keys on the control panel still light up (and beep when pressed) but the "mains" light in the top left hand corner is no longer on.
