well done Peter James, I powered down then up without the battery, and "ping" the box came back to life, and all is now ok. lots of green lights, thanks , I guess that's why you have the title of FAMOUS MEMBER. Hears to the next 30 years.

Matt further to your experience with your bedroom project the Everspring alarm system HA-28 from Maplins, I have been using two of these for 30 years in mine and my daughters house, and only this week I had a problem as I accidently set of the control box tamper. The box cut out and now I only have the mains light on. the good battery back up is not showing its light , there is no other sign of life. I have tried your suggestion switching out all the zones and repowering up but apart from the ac light, the box is dead. the 3 fuses inside are ok. the manual which I have, made no mention of recovering from the tamper. you may be surprised to know you are the only reference to this box on the whole world wide web, any advice, I tried to down load your suggested info but could not get it off the MSN group.
