Alarm Reset

[Andrew]

Moved in for a few months now ? Power cut and I don't have the alarm code how do I reset ? Any ideas many thanks

Have you tried Hare Krisna?

On the original alarm at our last house I observed the engineer disabling t he tamper in order to service the main box and that simply involved pressin g all the non-numerical buttons on the keypad across the bottom and up the right hand side and it did not even require our key code. How universal tha t is I don't know but to change/reset the keycode still required knowing th e present code, though I suspect gaining access to the PCB there might have been some means of doing a factory reset.

You need to obtain the Engineering Guide, or Installation manual for whatever alarm you have.

Bit late now but the vendor should have told you when you bought it.

Knowing the maker and model number would help a lot. Or a photo.

Most decent alarms will continue to work normally over a modest power cut and return to normal operation when power resumes. An alarm isn't much cop if you can disable it by interrupting the mains.

The time when you notice that you don't have the engineering code is when you want to decorate and tamper with the PIR sensors.

Alarms conforming to British Standards have required the user code in addition to the engineering code for decades now to go into engineering mode, so that an engineer cannot access/disable it without the user's permission.

So how does the engineer give the user a new code when the user has forgotten it? You can go into engineering mode on the alarm systems I fitted without the user code. You cannot turn the alarm off using the engineer code, it will go off if set and it will take a while before you can reset it. I assume this is to stop the engineer breaking in.
