Could some kind person point me in the direction of a recommended installer for the Chester area.

I have a recurring tamper fault that needs expert attention. I've checked all connections on the tamper circuit and they're all fine. I've also put a new battery in and replaced all the sensors. I suspect the fault is with the sensor or wiring in the garage as the alarm commonly goes off in the morning when the sun hits the garage roof and warms it up. The fault did stop happening for a while after I put in the new sensors last year but has recently started again.

The alarm system is a Challenger.

Did you check the bell?? Sun comes up and with heat/moisture that is causing the bell to fault??

Thanks for that Scottish engineer - believe ot or not that is the one thing I didn't think to check the connections on. I'll do that today and see if it helps. Unfortunately, as it's an intermiittant fault, I won't really know for a few days if that's the answer but it does give me something else to try.
