hi is it possible to use a battery smoke alarm, take the board off it and solder two wires to the place where the piezo is connected to, and then connect the two wires at the end, to a relay? So when the smoke alarm detects smoke, it activates the relay and piezo?
This is a normal 9 VDC battery smoke alarm.
