The alarm started doing odd things 2 days ago and was fine previously, now it is going off indoors every 10 minutes showing the tamper light. I have no instructions, how do I disable completely or fix?
If I unscrew front off what I think is control panel or remove fuse will it go off ? Its 3am dont want to wake the neighbourhood!

the end station is a white metal box,with two screws holding the lid on,but be aware,if you open it,you may need the engineering code to reset the panel,better to call an engineer out,and the 9427 is the model of the keypad,you have a scantronic system

3AM,we were asleep. How did you stop it?
If you think its the cover, do not touch it is the answer, could be the fuse board.
