As houses in Perth have double brick walls and concrete sub-floors, and the wiring is in the wall cavity (and it is a 2 story house) wiring is almost impossible to get to after the house is completed! As I said, I\'ve swapped the sensors to another input and I\'ve had one false alarm since. I\'ve now defined the sensors as a custom i/p type, and use a response to see if it is a real security breach or an intermittent glitch! The room also has a PIR so if that doesn\'t fire, it\'s a good indication that it is not a breach. Short term fix? Yes, but the best for now without MAJOR difficulties! One other point - most (but admittedly not all) false alarms have been in the early hours of the morning - 2am to 3am - so I doubt it is electrical interference as nothing is \"on\" at that time - no lights; no air-con, etc. I\'d expect interference problems to show as units were switched on or off rather than a steady-state current...... As we are just coming out of winter, I did wonder if it was a temperature related problem as that is when it is coldest...well, 7 or 8 degrees is cold for us!!]Quote:Well, I may have spoken too soon.You say you have it on a digital input! magnetic contacts do not use a digital imprint as they are strictly an open/closed circuit,
You should have the zone setup as Door/window input in comfort comfigurator it should not make any difference that the contacts are in series......
If it is setup as a digital input and the cables are run within 100mm of electrical cables their is a possibility of an emf field causing it to trigger a response (unlikely but a possibility)
