I constantly keep having my outside bell go off on my intruder alarm. The fault says "tamper" but nobody has tampered with it. The company has been out endlessly but we never seem to get to the bottom of it. The usual remark is its something to do with temperature flucuation. Surely not or all the alarms on my side of the road would be going off. Any help greatly appreciated my neighbours are getting very fed up as am I. Worst of all I can't stop it until the engineer arrives it just keeps going off randomly. Help me if you can please. Engineer coming again today perhaps you can point him in the right direction!!
