This is winding me up now.
Checked resistors across door contact, they were just about in spec. Went to RS components to get new ones.
Replaced resistors and replaced the original 2 core wires with two that weren't originally being used. Same problem!
I'm running out of ideas. I've linked out the tamper at the PCB, internal control box battery seems ok, and I've replaced door contact, resistors and wires.
Any other suggestions more than welcome.
For my own sanity, I've disconnected the internal sounder and the siren in the bell box, so when it triggers only the keypad rings/alarms. Could this be anything to do with it? I didn't want to attach the Sounders as they're driving me mad.
Thanks.
