Hope that someone can help - I've just moved into different premises and there is a galaxy 48 on the wall, but all the cables had been disconnected. Well I've figured out the keypads and the detectors but there is a six core cable going to the bell box and I am having trouble with it to say the least!
Obviously (I think) that red is +VE and black is 0v, blue and white seem to be tamper which leaves green and yellow. But when I connect them the siren either remains silent or goes off constantly.
So am I connecting to the correct place? the RIO outputs, or do I need to fit resistors?
Apologies if this is a stupid question. all my previous alarms were far less complicated :-)
