The answer to 'smoke detector power surge' is that a power surge can potentially damage or disable a smoke detector. Smoke detectors are designed to operate on low-voltage power, typically from a home's electrical system or battery. When a power surge occurs, it can overload the detector's circuits and cause it to malfunction or stop working altogether.
Common causes of power surges that can affect smoke detectors include lightning strikes, faulty wiring, or issues with the home's electrical panel. Symptoms of a smoke detector affected by a power surge may include the detector not responding to smoke, beeping intermittently, or failing to power on. The solution is to replace the affected smoke detector, and it's generally recommended to have a professional electrician inspect the home's electrical system to identify and address the root cause of the power surge.
