have you tried holding a magnet near a reed switch to keep it closed while you open the door or window? I haven't but it would be interesting to find out.

You need to know exactly where the reed is hidden, and also which way round the existing magnet is - or you've got a 50% change of setting the alarm off when you apply your magnet!.
Yes I know that Nigel but it is fairly easy to find the switch since it has its own magnet and the polarity can be found without operating the reed, I prefer to use plate to plate contacts not because of reed problem,I just thought of that, but because they're cheap and reliable. I was born in Sheffield and hiked around Derbyshire in my youth,durint war tha nose.
