No Call out fees or hidden charges

The first step to solving the problem is checking your batteries.

If you're hearing chirping even though they have a new battery, try these troubleshooting steps for clearing out residual charge from old ones!

1. Remove the alarm from your ceiling or wall. 
2. Open the cover and take out the battery.  
3. Press and hold the test button for 15-30 seconds. This will fully reset the smoke alarm and drain any charge left inside. 
4. Insert the new battery  and close the battery compartment. 
5. Clean the unit with a microfiber cloth or a can of compressed air. Vacuum the outside with a soft brush attachment. 
6. Press the Test button. The test sequence will be very loud, but it tells you the alarm is working properly. 

Note: The date on your battery package should always be checked to make sure they're fresh. If you store them, especially in cold areas like refrigerators or freezers where temperatures can cause batteries lose their charge more quickly - keep plenty of replacements around so that when an alarm goes off at night (or during any other time), someone will hear it!

There are a few possible causes for your smoke alarm to keep chirping.

1. It might be time to buy a new detector. Check the date of manufacture printed on the back of your alarm to confirm it's not expired. Most alarms expire 7-10 years after the manufacture date.
2. It is possible that your smoke alarm “silence” button was pushed by mistake. The alarm will now “chirp” once a minute for up 15 minutes before resetting.
3. Other devices have similar low battery chirps or warning tones that sound like the chirp a smoke alarm makes.
4. AC interconnected alarms may chirp every 5 seconds if the interconnect wire is grounded. The interconnect wire should not be grounded.

Step 1: Silence your alarm

To silence a nuisance alarm, press and hold the Test/Silence button on your unit. This will quiet the horn so you can find what caused the alarm. 

Step 2: Review these fixes

The steps to fix the nuisance alarm will vary depending on the cause of the alarm, whether its dust in the sensing chamber or a nuisance alarm caused by shower steam.

Take a moment to review these questions to help uncover the cause of the false alarm and correct possible underlying issues.

•    When was the unit installed?

Check the manufacture date on the back of your unit. Alarms expire over time. If your alarm is older than 7-10 years, it’s time to remove the old alarm and replace it with a new one.

•    Has the unit been cleaned recently?

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. 

•    Is the unit installed near a source of steam, moving air, direct sunlight, HVAC vents, or fluorescent lighting?

Certain alarm locations in the home are more likely to cause nuisance alarms. Follow our smoke alarm placement guidelines to ensure your alarm is installed far enough away from kitchens, bathrooms, furnaces, or fireplaces.   

•    Have you experienced power issues or outages recently?

Hardwired alarms may briefly sound when power is interrupted, then restored. Power interruptions are common in areas where utility companies switch grids in the early hours of the morning. In AC or AC/DC smoke alarms, a loose hot wire connection can also disconnect power to the smoke alarm. The effect is the same as a power failure. When power is restored, the units may alarm briefly. If any of this might be the case in your home, we recommend reaching out to an electrician.

•    If battery-operated, is the alarm installed over a junction box? 

Battery-operated alarms are not designed for junction box installation. Installing battery-operated detectors over electrical junction boxes may cause false alarms. Try relocating the alarm. 

•    Is there an alarm malfunction?

If you eliminated all the possible causes above and your unit is still nuisance alarming, please reach out to one of our consumer support representatives to assist.
