Do I need to be an electrician to unplug a mains powered smoke alarm?
Smoke alarms are designed to allow for easy maintenance, cleaning and testing. For this reason you should find that if you have a mains powered smoke alarm it will be easy to detach it from the base plate that provides power to the alarm.Base plates that provide power to a smoke alarm will be screwed to the ceiling or wall. Do not attempt to remove the base plate that is screwed to the ceiling or wall. These base plates must only be removed by a licensed electrician.
