Hi, I recently bought a house where there is a Challenger 5 alarm fitted, and loads of sensors everywhere. I know ot was fitted in 1995 and don't think it has been serviced ever since. It is still connected, although the "tamper" light is on, probably indicating a fault. I want to disconect and remove the whole thing, but I'm not sure where to start with. Any advice? Thanks
