    Replaced our 10 year first alert alarms. So far so good! I would recommend this brand as it has been a long time favorite for our family. No complaints on our end. Highly recommend first alert smoke/carbon monoxide detectors

    False Alarms at all hours of the night

    I bought a couple packs of these alarms and have them in every bedroom and floor. They randomly alarm and trigger for no reason. We are uninstalling them all and replacing with Nest Fire Alarms due to the lack of reliability.

      Hi AnthonyB, this is not what you should expect. Please press and hold the Test/Silence button on your unit, this will quiet the horn so you can find what caused the alarm. Check for bugs, debris, or dust in the sensing chamber. The inside of the alarm might have been triggered by hidden dust, dirt, or spiderwebs. Regular cleaning prevents most nuisance alarms. Clean the detector with a can of compressed air and your vacuum’s soft brush attachment and reinstall the alarm. Clean your detectors once a month. Never use water, cleaners, solvents, or air compressor machines to clean your alarm. Test the detectors once a week and change batteries once a year. Contact First Alert Customer Support at 1 (800)-323-9005 for troubleshooting assistance. - Maria FirstAlert

    Too many false alarms!

    I have had so many false alarms with this alarm. Horribly, unbearably loud. Troubleshooting did not work. Had to cut the breaker and take out the batteries to get it to stop.
