To get your smoke alarm to stop chirping if you've already changed the battery, first try draining any residual charge by holding the test button down for 15 seconds. If this doesn't solve the problem, clean the unit. A blast of compressed air will often remove the dust particles that are causing the beeps.
Reset the Smoke Detector: Sometimes, a smoke detector just needs a good reset to stop the chirping. You can do this by turning off the power at the circuit breaker, removing the detector from the mounting bracket and disconnecting the power supply. Then, press and hold the test button for about 15 seconds.
Will a smoke alarm eventually stop chirping? A smoke alarm will eventually stop chirping if it stops detecting smoke or if the condition that created the false alarm is fixed. For example, if dust and debris is causing your alarm to sound, cleaning it will stop it from chirping.
Your home security system likely has a main source of power, which is a box that is secured to the wall with an outlet. This box is the key to turning off the alarm while there is no electricity. Simply disconnect the box from the outlet by unplugging it.
Press the Silence or Reset Button: Most domestic fire alarms have a button to temporarily silence the alarm. If the underlying issue has been resolved, pressing this button should stop the alarm.
The beeping sound the low battery alarm makes can become very annoying but can be disconnected by removing the drained battery from your home alarm system panel. Make sure to replace the drained battery with a new one to keep your home alarm system functioning properly.
Several common causes can explain why your hard-wired smoke detector is beeping: Low battery: Even hard-wired smoke alarms have backup batteries that need replacing periodically. A low battery can cause that annoying beeping sound. Dust buildup: Dust and debris inside the smoke detector can trigger false alarms.
Press the silence or reset button: Most alarms come equipped with a “silence” or “reset” button. Locate this button — often on the front or side of the device — and press it firmly. This action usually stops the beeping temporarily while you address the cause, such as replacing a battery or cleaning the unit.
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.
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.
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.
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.
'Low battery chirp' is a short high pitched warning sounds emitted by your smoke alarm every 30-40 seconds. Pressing the 'Hush' button will force the alarm into 'low battery hush' mode, temporarily silencing the low battery warning for 8 hours, to give you time to replace the 9V battery.

The basic instruction for temporarily silencing your alarm system is to press the silence or hush button, which will deactivate the triggers for a few minutes. Most smoke detectors have this button named 'test,' which you can press and hold for a few seconds to get the job done.
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.
Smoke detectors have a built-in residual charge, even with the battery removed. Press down and hold the test or reset button for a minute or so, this should drain it and shut it up.
Most systems will begin beeping or chirping as a result of a total power outage or failure to recharge the system backup battery. For many of our most popular systems, beeping alarms and low battery trouble beeps can be silenced by pressing the [OFF] or [#] buttons from the keypad.
This is normal because the battery was drained during the power outage, and just needs time to recharge.
