Use a quality battery duracell or energizer. Not ones from the dollar store.

Chirping means low battery.

Most smoke detecotrs have a limited lifespan of 5-10 years. On the underside of the detectors should be a sticker with installed dated or replace by date. If changing the batteries doesn't stop the chirping it is most like time to replace the detector. If you check the manufacturer website they will give you a life expectancy for your detector.

Hi,

Here are the steps:
Was this always like this? If not, change the batteries, clean it up. Consult the local fire dept. The help for free.

If that does not work, you will need to get it serviced/repaired.

I installed a new smoke alarm battery only 3 weeks ago. It started chirping yesterday. New battery and it has not stopped chirping since.


The battery you installed may be defective or expired, replace it again with a major brand like Energizer

My hard wired smoke alarm has had a new 9 volt battery installed and even a second new one installed and is still chirping 4 times every 30 seconds.


On many of the newer smoke alarm installations, all of the units are wired together so that if one goes off, it triggers all of the others so that no matter where you are you will definitely hear the maddening noise of the alarms! And if one of the other units has a bad or weak battery not only will it chirp but so will the others.

Only way around this is to cut any and all wires going to each smoke detector. They will still work because each has its own battery but there will be no more triggering of other units.

How to fix a hard wired smoke alarm that won't stop chirping


you don't say what kind of smoke alarm you have, or what kind of chirping, so i'm assuming it's a once per minute chirp which usually indicates low battery, but can also indicate that the unit has some other problem...if the unit is more than 10 years old you should replace the entire thing (per NFPA72, the national fire code, all smoke ALARMS must be replaced every 10 years)...if this is newer than 10 years, try replacing the 9 volt battery being careful to follow any instructions that may have come with the unit or may be printed on the back, top or sides...good luck.

My Kidde Model 1285 keeps chirping even after I changed the batteries, any ideas why?


Be sure you are using a well known brand battery. The store brands, in my my opinion generally are not quite up to par. Try this and see if the chirp will stop. Thanks for asking me.

My new Firex 21007581 with a new battery keeps chirping. What is the problem and how do I fix it? Thanks Sal


He said it had a new battery so he already did that and why would you service a $12 throw away smoke alarm? This FIREX he identified is the 4618 and will also chirp while the LED light blinks, chirp is about 30 seconds after blink if the unit itself needs to be replaced because there is something wrong with it as opposed to a different chirp pattern for battieries. If still unerwarrantee FIREX will replace otherwise go buy a new one.

Kidde # 1276 chirps indicating low battery. Battery replaced and chirping continues. Why?


Don't know for sure, but if your smoke detector is more than 5 years old, than you have to purchase new one (that's their average lifetime). Take a look on amazon: Amazon com smoke alarm. I hope I have helped. Cheers

Replaced 9 v batteries, units still chirping


This is the troubleshooting information from the kddie site. The problem is usually related to an older battery or improperly installed battery. You might also have to do a reset as described below. If battery and cleaning don't work, it might be time for a replacement - short money to keep you and your home safe.

  1. The battery may be loose, or improperly installed.
    Verify that a battery of the recommended type is securely installed. Make sure to use a battery with a use-by date no later than four to five years in the future. Check that the battery is snapped in completely so it cannot be shaken loose. It’s possible that battery connections may not be making good contact with the battery. Disconnecting and re-connecting the battery once or twice will likely fix this condition. On units with a front-load battery, be sure that the battery compartment door is closed completely as well. Loose white neutral wire can cause an echoing chirp. (From one unit to the next)

  2. The smoke alarm sensing chamber may be dirty.
    Dust and insects can collect in the sensing chamber of the alarm. An accumulation of dust in the sensing chamber can cause the unit to chirp. It is good practice to clean the smoke alarm when you change the battery. Static electricity from the ac quick connector attracts dust and can cause false alarms.

    Cleaning smoke alarms:
    To clean your alarm, remove it from the mounting bracket as outlined here. You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The outside of the alarm can be wiped with a damp cloth. After cleaning, reinstall your alarm, verify the green LED is on and test your alarm by using the Test Button. If cleaning does not restore the alarm to normal operation, the alarm should be replaced.

  3. Check environmental conditions:
    • Humidity, steam and condensation can cause false alarms. Causes of condensation are:
      • Extreme temperatures changes.
      • High ambient humidity.
      • Unit being installed in an uninsulated electrical box mounted on a ceiling beneath an attic. If this condition exists you’ll want to move the alarm. Click here to see the correct alarm placement in your user’s manual found in our Download Center.
    • Check to see if there is a cooling/heating register, a ceiling fan or an open window within 3 feet of the alarm. If there is, move the alarm away from the source of the increased airflow. Click here to see the correct alarm placement in your user’s manual found in our Download Center.
    • Check the temperature of the room. Smoke alarms operate at 40 degrees to 95 degrees Fahrenheit. Carbon monoxide alarms operate at 40 degrees to 100 degrees Fahrenheit.

  4. Reset the alarm.
    Some current model smoke alarms have a processor that retains certain error conditions, such as a weak battery. The error condition should reset when the battery is replaced but sometimes it does not and must be manually reset to clear the error.

    To reset an AC unit with a battery backup:
    Turn off the power to the smoke alarm at the circuit breaker.Remove the smoke alarm from the mounting bracket and disconnect the power. Remove the battery. Press and hold the test button for at least 15 seconds. The unit may chirp or alarm for a few seconds before going silent.Reconnect the power and reinstall the battery. The unit will chirp once when the power is restored and should not chirp afterwards.

    To reset a DC only unit:
    Remove the battery. Press and hold the test button for at least 15 seconds. The unit may chirp or alarm for a few seconds before going silent.Reinstall the battery. The unit will chirp when the battery is first connected but should not chirp afterwards.

  5. An electrical condition may be causing the power to the unit to be interrupted.
    If the AC power to the unit is interrupted, the unit will chirp when the power is restored. This could be caused by power surges.
    If the chirping seems to occur at about the same time in the evening or morning, it could be due to a surge created when the power company switches electrical grids to meet demand. Check to see if the chirp (or chirping) occurs when something else in the house is turned on such as an exhaust or attic fan, a heater, etc. If the smoke alarm is connected to a circuit with such a device, the alarm may chirp when the other device is switched on. If this is the case and the device is plugged into a wall outlet, move it to another outlet on a different circuit. If it is a hardwired device, have an electrician investigate it. These conditions can be minimized by installing your alarms on a dedicated circuit in compliance with NFPA requirements.

  6. Replace the alarm.
    If none of these conditions exist and the suggestions don't alleviate the symptom, the alarm should be replaced. Age may be a factor. Smoke and heat alarms should be replaced every 10 years, and carbon monoxide and combination alarms should be replaced every 7 years. Most of our alarms have a 5 year warranty from date of purchase (check your user manual for details). A date code is stamped on the label attached to the back of the unit.
