How do you test a smoke detector?
If you want to test a smoke detector, find the test button on the front or side of the unit. Push and hold the button for a few seconds to ensure the alarm sounds. If it doesn’t, you may need to replace the batteries or have an electrician check the wiring in the detector.
Why would a smoke detector go off for no reason?
Dust can reflect the light particles, similar to smoke, which gives you a false fire alarm. To clean, simply remove the outer casing. Leave a careful amount of space between the smoke detector and bug spray. Keep in mind that harsh chemicals can also cause smoke detectors to go off.
Why is my First Alert smoke detector blinking green?
