Hi, My son has recently moved into a new build property with above alarm panel fitted. No paperwork (user or installation manuals) have been left. There is a sticker on back of remote keypad with installers details. I asked the Persimmon homes rep for information regarding engineers code etc to allow me to reset part set function to suit our requirements and for any further work we wish to carry out on alarm ( additional sounders and rkp's, new zones etc) and was told to contact installer. This i did and was told they don't give this info' out and tried to sell me a service contract! I am not an official alarm installer but have fitted at least 12 units for friends and relatives. Where do i stand regarding this information, is it not mine anyway (or my sons!) been the purchaser/owner?
