I had a power cut this afternoon, during which the internal sounder for my alarm system (which has never been used) sounded continuously and the control panel started beeping continuously. I've 'fixed' the sounder by disconnecting the speaker but the control panel is still going.
The alarm system documentation refers to it as a CEF AP28. The control panel says 'Challenger Security Systems'. I've attached an image (the actual unit is horizontal). The green mains light flashes occasionally (and there seems to be an unlabelled amber light next to it which flashes at the same time). The amber "day" light flashes continuously. All the other lights are on continuously.
Suggestions? The system is not under maintenance and was installed more than 10 years ago (I know not by whom). I would really like to be able to sleep tonight... probably best to assume that I'm dumb and blond, even though I'm neither. I have (and have read) the User Manual, and have downloaded and read the installation manual (but that's well beyond my skill level).
I've tried: the reset code. Arming it, leaving the house, returning, disarming it.
