Hello everyone,
I've got a very frustrating problem with our old Mini-8 alarm set up and wondered if anyone out there can help with suggestions.
The system came with the house and consists of a PIR wired to one zone, and ITEC Window sensors and a door contact wired serially to another zone. The tamper circuit is not used.
The system is old but was working reliably until we had windows changed. I removed the sensors prior to changing the windows and when I've come to re-wire them, the system won't arm and instead blinks and sounds the fault condition for the wired zone.
I tested each of the sensors out of circuit on my multimeter and they all are closed as I expect they should be. I'm not sure how these sensors work but I imagine a physical shock causes them to go briefly open circuit. Screwing them back in circuit brings the fault back.
I've tried twisting all the wires together around the house to close the loop and introduce a sensor one at a time, but the results are erratic. For instance, install sensor 1 - can arm OK. Install sensor 2, get a fault condition. Remove sensor 2 and the fault condition is still there until I remove sensor 1.
The alarm does accept the 9999 enginner code, but a reset doesn't make the fault go away.
Am I missing something obvious about the sensors? I'm starting to wish I never unscrewed the things!
thanks for any tips!
