That's a perfectly fair opinion It's why I'm asking for advice on a good fitter in the area too. I'll see if I can find the websites you mention and see if they suggest anyone.

Sorry I never reported back on this. I (planned to) took the advice to go with the suggested replacement, but the alarm fitter disappeared off the face of the earth. Tried to get in touch with him for months with no luck. Eventually, on a whim, I did something that I should have tried at the start. I hypothesised that the nature of the fault on the tamper switch might be that if it was pushed in more firmly, it would make a better contact. It's only returning to the thread that I see this: I think that's referring to the same idea, right? Anyway, I attached a sticky foam pad to the 'spur' which contacts the tamper switch, and it fixed the problem completely! That must have been back in around August. Unfortunately, the issue has now reappeared. The pad was pushed in, so I added a fresh one, but no dice this time! Perhaps the switch has become that little bit more broken, and now even this trick won't work? Anyway, I'm back to square one. Get someone to solder a new switch in place, of get the lot replaced. But I don't know a reputable alarm company in the area any more. So, my questions to you good folk are: Know a good fitter in the Macclesfield area? Do you know whether its an open or closed circuit which sets off the tamper alarm? I'm thinking that just removing the button would fix the problem if it's a closed circuit that sets it off (although obviously I would no longer have a tamper alarm). If I use the other keypad to put the system into engineer mode, then remove this keypad, get someone to fit another switch to it, then replace it, will it need to be reprogrammed?

Yeah, I suspected it wasn't a bad price for what he was offering (good to hear it confirmed though!). Just wondered if there was a completely different solution that could save a lot. Thanks for your thoughts. There's a 3400 keypad on eBay, which looks all but identical, but I assume they're not compatible?

Hi All I have a Scantronic 9600 system, and the main keypad has developed a fault with the tamper switch on the back - resulting in it setting off every few seconds, as it believes it is being tampered with. I know the whole system has been discontinued, but this is resulting in my fitter suggesting two new keypads and a control unit, at about £480! Can anyone advise how likely I am to be able to just get a replacement keypad somewhere (and where? and whether it'll just be plug and play?) Or, alternatively, is this a known fault - and if I remove the keypad and take it to an electrician, is there any chance he'll be able to replace or fix the switch on the back? Thanks in advance for any help anyone can offer.
