Mr.T.

Hi Guys, At first I would like to say hello to all of you. I've recently bought a house where there is old ADT installation which I would like to remove. However I'm not quite sure if I can do it without triggering anything(I know alarm is deactivated and there's no contract with ADT at the moment). I would normally first do a search but I don't even know what model it is, that's a picture of it: Picture of old ADT central panel If I would start taking everything apart, disconnect cable, disassemble panel will it trigger the siren? Is there any additional 'hidden' module that would trigger it? What would be the best way to approach that? Also I would like to put something new in place, as far as I've seen people recommended: Honeywell galaxy flex something from Texecore Will that be easy enough for a person with some DIY/bit of electronic/IT skills to fit it? Will I be able to use existing wire connections for the siren(my guess is a yes) Many thanks for all the answers and kind regards, Mr.T.
