Pressing the “Test/Silence” button on the front of the unit should stop it from beeping or chirping. If this doesn't work, grasp the device and turn it counterclockwise. It should detach from the base so you can open the battery compartment in the back. Remove and replace the battery to see if it caused the issue.
Silence Button: Many smoke detectors have a ``silence'' or ``hush'' button. Press this button to temporarily silence the alarm. This is often effective for a short period, but the beeping may resume after some time if the battery issue persists.
If you have a battery smoke alarm, yes, removing the battery will stop it chirping. Removing the battery will also stop it being a smoke alarm any longer, so your best course of action here would be to just change the battery while you're at it.
Common reasons why fire alarms beep randomly at night include low batteries, dust buildup, or environmental factors like humidity or temperature changes. These devices are designed to alert you to problems promptly, ensuring your safety by encouraging immediate action to maintain their functionality.
Will a smoke alarm eventually stop chirping? A smoke alarm will eventually stop chirping if you do nothing. Once the battery has run out completely, the device will switch to residual power. Eventually, this will also drain and the device won't have enough power to beep and let you know it's out of power.

While your smoke alarm sounds, pressing the hush button will silence the smoke alarm for approximately 10 minutes. The hush feature is typically used where an alarm has been triggered accidently. This provides time to clear the current environment of fumes that triggered the alarm without the alert tone sounding.
Dust and debris can easily accumulate inside your hard-wired smoke alarm, causing that incessant chirping sound. This build-up can interfere with the sensing chamber, triggering false alarms. To prevent this, make a habit of cleaning your smoke detectors regularly.
How Long Does A Smoke Alarm Chirp Before It Stops Working? If you have a battery-powered smoke alarm, it will chirp for about a month before the battery dies. But if it's a hard-wired alarm with both AC power and a backup battery, it will keep chirping until you replace the backup battery.
Press the hush/silencing button. It will silence the entire interconnected system. The button may also say “test.” It should silence all the alarms immediately unless there's still smoke and debris. It will reset in eight minutes, given that the smoke and debris have dissipated.
All First Alert Alarms come with a Test Button. With the battery removed from the unit, press and hold this button for 30 seconds. This will fully reset the alarm, removing the residual charge of the previous battery.
Disarm the alarm system
The process for doing this differs for each system, but one of the following is usually recommended: Enter the passcode and disarm. Arm the system, and then disarm it, immediately. Press the status button on the keypad.
The smoke alarm is desensitized by pushing the “Test/Hush” button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately. If the smoke or debris is interfering with the sensor, the alarm will override the Hush.
Your smoke detectors don't have an inside voice — for your safety. If you hear your smoke detector beeping in brief chirps every 30-60 seconds, it's probably time to replace the battery. Or you might need to clean out the dust, check the battery connections or replace the whole smoke alarm.
You may get a false alarm if the battery life is fading or if the detector isn't properly connected. To check the battery, remove the outer casing and check to ensure that the old battery is properly connected. If so, it's a good idea to replace the batteries.
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.
The hush feature on an alarm will desensitize it to smoke for 7 minutes meaning, if you know every time you cook with oil it will go off, you can hush it beforehand to avoid the blaring sound. It will, however, let out a small chirp every 30 seconds, to let you know that the alarm is still hushed.
First, try the reset button on each smoke alarm. If that doesn't work, flip the circuit breaker off and on. If that fails, you may have to disconnect the smoke alarms and remove the backup batteries inside them one by one. (The batteries are there to protect you during a power outage.)
Clear Residual Charge to Stop the Chirp
Press and hold the test button for 15-30 seconds. This will fully reset the smoke alarm and drain any charge left inside. Insert the new battery and close the battery compartment. Clean the unit with a microfiber cloth or a can of compressed air.
What Does a Beeping Fire Alarm Mean? Unless there is some kind of smoke or fire emergency, a smoke alarm beeping every 30 seconds signifies that it is low battery. Sometimes though, other environmental factors can cause the alarm to beep more than normal.
A hard-wired smoke detector usually chirps because of 1 of these 3 problems: A dead backup battery. Dust inside your detector. Malfunctioning/old detector.
