old optima system with 3 door sensors 4 pir and 2 panic alarms keeps going off and showing tamper for no reason. It goes off when my heating comes on in the morning,will not always reset straight away,some times it goes off in the evening when my heating goes off ,"could it be haunted or just taking the p..." all seems very strange!!!
