Hi guys, right I think I'm going to fit a new bell unit, check over the circuit and go from there as I say it's been a while since install and although it's been pretty trouble free, it obviously needs looking at!
Do do I take it any bell unit sold today will still fit ok? I'm going to change the door contact and the kitchen pir as although I'm sure it's a pet unit they do have a dog again now, although like I say it doesn't go off when it's set, so it's not the Jack Russell in the kitchen.
Thanks
