How much to connect a smoke alarm for a loft conversion to the main electrics which the others are connected?
just rough idea ta xx
Answers:
Mains powered smoke alarms with battery back up, are interlinkable with 3 core cable, this way when any one senses smoke, they all sound off. It depends how accesible your wiring is but it should cost around £65.00 + the cost of the alarm.
It's best to have them not plugged into the mains, because when you have a power cut, the alarm is deactivated. Get one that uses a battery. You only have to change the battery once every few months, and it's safer!
There are smoke alarm units that stick in place, sometimes with a magnetic tape.
