Removing a hard-wired smoke detector is a relatively simple task that can be completed in a few minutes. However, it is important to take the necessary safety precautions to avoid injury or damage to the electrical system.
Before you begin, you should turn off the power to the smoke detector at the circuit breaker panel. Once the power is off, you can remove the smoke detector from the ceiling or wall by unscrewing the mounting screws. Be careful not to damage the wires when you remove the smoke detector.
