Connecting fire alarms to burglar alarm
Hi All,
We have a burglar alarm with a couple of spare "zones". Unfortunately, when we had our fire alarms fitted (mains powered and all interlinked), I didn't think about integrating them with the burglar alarm so we will be notified if the fire alarm goes off whilst we are out of the house. I was wondering, if I put a relay in, would I be able to connect the 2 together such that the burglar alarm treats it like any other zone in the house. My logic (which may well be flawed!) is as follows.... - connect the 240v interconnect from one of the smoke alarms to one side of the relay (I have assumed that the interconnect goes "live" when the fire alarm goes off - is this true or is it a switch?) - connect the 12v alarm wire to the other side such that the relay opens the switch when it gets 240v the other side (i.e. breaks the alarm feed and sets the alarm off). I'm sure it is not really this easy ..... and would greatly appreciate any help you folks can give me. thanks Lee. |
