The battery may need to be replaced. An alarm will chirp every 30 to 60 seconds for a minimum of seven days. With a "low battery" announcement, disconnect the unit and replace the batteries. You can also put a unit into low battery hush for up to 12 hours on newer units by pressing the test/hush button.
If your smoke alarm is emitting a single high-pitched chirp every 30 seconds or so, it's most likely a sign that the battery is running low and needs to be replaced. Stopping the problem is a simple matter of changing it out.
A single beep about every 30 seconds to a minute can mean the battery is low, the sensors are dirty, or the unit needs to be replaced. Multiple beeps can indicate a malfunction, or if the unit can detect carbon monoxide (CO), high levels of the gas may be present.
When the detector is making chirping sounds every 30 seconds, this is not the same as a continuous siren. The chirping sound usually indicates the alarm is near its end of life and requires replacing. Carbon monoxide detectors have a seven-year lifespan. Replacing the battery does not stop this type of beeping.
Consistent Chirping
If your carbon monoxide alarm is chirping or beeping once every 60 seconds, it may signify: Low Battery – The carbon monoxide batteries need to be replaced. End of Life Warning – Seven years after initial power up, a Kidde CO alarm will begin chirping every 30 seconds.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.

This battery characteristic can cause a smoke alarm to enter the low battery chirp mode when air temperatures drop. Most homes are the coolest between 2 a.m. and 6 a.m. That's why the alarm may sound a low-battery chirp in the middle of the night, and then stop when the home warms up a few degrees.
A single chirp – repeating every 30 to 60 seconds – means your alarm battery is low and needs to be changed. If your alarm continues to chirp after replacing the battery, that means the alarm unit needs to be replaced.
Clean The Alarm
Dust and debris can affect the alarm. As far as it is concerned, the spider web or speck of dust that is obscuring the sensor is a potential fire and therefore the alarm needs to be sounded. The easiest way to clean an alarm is to run a vacuum cleaner over the vent.
Interpreting your carbon monoxide detector:
A single chirp every 30 or 60 seconds means the battery is low and must be replaced. CO alarms also have “end of life” sounds that vary by manufacturer. This means it's time to get a new CO alarm.
When the unit is in alarm,You can put your Smoke Alarm in HUSH mode by pushing the test/reset button. If the smoke is not too dense, the alarm will silence immediately, and the green LED will flash every 2 seconds for approximately 9 minutes.
If you replaced the battery and it's still beeping, the smoke detector might have expired like milk. Smoke detectors have an expiration date. The sensitive equipment inside can only work reliably for so long, so if yours is beeping and its expiration date has passed (or will in a year or two), it's time to replace it.
Break through the label with a screw driver and turn the screw to the “OFF” position. This will deactivate the alarm, stop the end-of-life warning and render the alarm safe for disposal by draining the battery. IMPORTANT: Deactivation of the alarm is permanent.
Clear Residual Charge to Stop the Chirp
Remove the alarm from your ceiling or wall. Open the cover and take out the battery. Press and hold the test button for 15-30 seconds. This will fully reset the smoke alarm and drain any charge left inside.

A flashing green light is a normal part of the power up cycle. Any time there is a power outage, brownout, surge or other problem with the power, the alarm goes through a power up cycle.
If the alarm emits a chirp every 30 seconds, it is either an end-of-life alert or a sensor error. If the alarm emits a chirp every 60 seconds, it indicates the battery power is not sufficient to power the unit in full alarm.
Kidde CO alarms have a proven life of seven to ten years, depending on the model type. Important Note! CO alarms do not detect the presence of CO when in end-of-life mode.
If you have a carbon monoxide detector chirping and then it stops, it's important to take the situation seriously, even if the alarm is no longer sounding. Even if the alarm has stopped, get everyone out of the home to a place with fresh air.
How to test your carbon monoxide detectors to ensure they are working properly? To test your carbon monoxide detectors, press and hold the test button on the alarm. The detector will sound 4 beeps, a pause, then 4 beeps for 5-6 seconds. Refer to the user manual for your specific model.
Yes, the fire department can check for carbon monoxide. If you suspect the presence of carbon monoxide in your home or building, it's essential to act quickly. Evacuate the area, ensure everyone's safety, and call your local emergency services or fire department.
