ThornGamma6 Posted April 13, 2017 Share Posted April 13, 2017 Hi, Today I was trying to fix a friends burglar alarm which has being going off in the day and at early hours of the morning sometimes. He asked me if I could take a look at it and so I did the tamper circuit and all the wiring in the devices such as PIR's, Door/window contacts, PA button and the bell box all looked ok and I couldn't see anything wrong with the wiring or the tampers on all the devices on the system. I did put a new back up battery in the panel just in case that was causing the problem and then I screwed the cover back on to the Optima plus and made sure it wasn't over tightened but still nice and secure. Then I just checked the 2 PIRs and the 2 door/window contacts and one of the PIRs is an old Aritech Ultrasonic and the second PIR is an old Microwave detector could the 2 PIRs be the problem?

MrHappy Posted April 13, 2017 Share Posted April 13, 2017 powered contacts & pa button ? 2 minutes ago, PeterJames said: Link it out at the detector, if it still keeps going off then its either the panel or the cable, if it stops then its the ultrasonic this the easiest way to DIY fault find, normally you take & record resistant readings of each circuit, Quote Mr Veritas God Link to comment Share on other sites More sharing options...
