Hi, we have an Optima Compact alarm, the external bell box for which has recently slipped. Have tried rehanging it, it worked for a while but recent windy weather has moved it again. Need to remove cover from bell box but understand I need 'engineer code' - originall installer moved from area. Can I do this myself, if so, how do I find out engineer code or is it the case of getting someone out? If I do have the code, sounds a silly question, but what exactly do I do with it e.g. do I enter it on main keypad in house? Would be grateful for advice. Thanks.
Andrew.

Hi Andrew, the default engineer code is 9999 (it may have been changed) but you don't need it, when you take off the cover the tamper will sound (or at least it should do) put in the user code (make sure this works before you start) to silence, fix the box backplate with at least 3 2inch screws in the brick/stone not the motar joint.
Replace cover and press reset.
