Smoke Detector Keeps Beeping

Answer: call a electrician.

A smoke detector that keeps chirping or beeping intermittently — even after battery replacement — may signal a wiring fault, a failing sensor, or an expired unit. Because smoke detectors are critical life-safety devices, persistent beeping should not be ignored. An electrician can test the circuit, replace hardwired units, and ensure your home meets current fire-safety codes.
