Do I need an electrician to replace hardwired smoke detectors?
They are hard-wired into our electrical system, but that doesn’t mean you need an electrician to replace them.
Modern hard-wired smoke detectors don’t have wires in the back that need to be connected to loose wires in the ceiling.
Can I disconnect a hardwired smoke detector?
If there are no wires connecting it to the ceiling or wall, it is a battery-operated unit and there are no wires to be removed. If there are connecting wires, it is a hard-wired unit and the wires can be disconnected. Dismount from the ladder and flip the circuit breaker switch that controls the smoke detector.
