The answer to 'smoke detector power surge' is that a power surge can cause damage to smoke detectors, leading to malfunctions or complete failure. Common causes of power surges include lightning strikes, faulty wiring, or electrical issues in the home. Symptoms may include the smoke detector not powering on, beeping intermittently, or failing to detect smoke properly.
In most cases, a professional electrician should be called to inspect the smoke detector and electrical system. They can diagnose the root cause of the power surge and determine if the smoke detector needs repair or replacement. DIY troubleshooting is generally not recommended, as smoke detectors are safety devices that require proper installation and testing.
