Just moved and new place has an old wired house alarm (movement sensors wired in most rooms) but looks like it’s not working and there are no window/door sensors.
Anyone installed their own alarm? Thinking I can prob get the wired sensors working again but would need wireless door/window sensors and a new main unit I’d guess.
I was doing a bit of decorating a couple of months back and wanted to replace the old PIRs (sensors) with new ones as they were shitty old ones covered in paint.
It's not quite easy as you think. They have a fair few wires going into them, one of which is a tamper setting (to stop people from ripping them off the wall without triggering the alarm).
I had a go at removing one which triggered the tamper setting and the alarm went off. Not a problem I thought, I'll just enter the code to silence the alarm and attach the new PIR. Turns out the new sensor couldn't be activated until the tamper setting was properly sorted out and I couldn't figure out how to do it even after reading the manual and pressing a multitude of button combinations.
Ended up getting an alarm fella around to replace all the PIRs in the house and moving one as it was in an area of the kitchen where its range of vision was obscured.
I believe the tamper cables/settings are an older feature and are not included in new sensors but still, my experience is that it's a bit of a twat of a job.
