Why Is My Smoke Alarm Blinking?

An individual carefully puts a battery inside a smoke detector, ensuring its readiness to detect smoke and prevent potential fires.

You’ve probably seen it before: You walk into a room and look up at the ceiling only to notice there’s a smoke alarm. Nothing strange about that, right? But then you notice there’s a red light blinking on it, and you think, “Why is that smoke alarm blinking, and why is the light red? That could be a problem, right?”

Why Do Smoke Alarms Blink?

Just about every residential smoke alarm blinks. A steady, periodic blink indicates that the battery/power supply is working properly.

Why Is My Smoke Detector Blinking Red?

A red light will flash all the time if it’s operating correctly, but only about once or twice every minute or so. If it’s blinking faster than that, it probably means it’s functioning in “hush mode,” which means the alarm was silenced for some reason.

You may also notice your smoke alarm has a green light. This means that AC power is operating the smoke alarm, so if it goes out, it means the power has been interrupted. If this is the case, check the circuit breaker and the wiring to fix the problem.
