There's an SD1 dialler hooked up to it too, looks an awful lot newer though.....obviously done a complicated way from what i've seen it uses a plug on relay interface with different outputs connected to the dialler (fire, intruder and panic)
I can't see a way to get in at all without triggering the alarm, i'm starting to suspect it was installed by an engineer who lived here as there's no recipets only the user and installation manuals and i do have the engineer code
I feel like a challenge so when the time comes i would like to give it a go in replacing the panel myself, like i said i'm very interested in the galaxy series (and i think the mk7 keypad as the newer one looks a bit tacky....same with the texecom premier)
Would using the current PIR's be reccomended? It's a mix of what i believe are racal apollo's and racal scorpio's, and in a keeping with the retro theme i'd like to keep the ultrasonic as it seems to be reliable.......the whole system has only false alarmed once (feel that was my doing though as the house has warm air heating and i left that on while out all day)
and yes i have done a vast amount of research on detector models before posting, as i didn't want to waste your time guessing what they might be
