hi, I've recently bought a house and it has a honeywell galaxy 2 alarm system installed in the house & garage. two alarms, two keypads but they're linked together. The guy who used to live there was a alarm & cctv expert but has passed away so i can't retrieve any codes as his wife only knew the front door code. we had a power cut, then we reset the house alarm ok ( we have the code for that ) but the garage one is still going off as we don't have to code to silence it, so, basically, i want to disconnect & remove the camera's outside the house ( weird i know ), reset the garage keypad & the front door keypad so we can make our own password....does anyone know how i do this? especially as i don't know the garage code for the separate garage alarm & its constantly beeping inside the garage. ( we don't have any instruction manuals either )
