Use thumb to pull deactivation tab outward until tab snaps into place. This will discharge the powercell and deactivate the unit.
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.
Pressing the “Test/Silence” button on the front of the unit should stop it from beeping or chirping.
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. Insert the new battery and close the battery compartment.

Removing an AC hard-wired or interconnected alarm
Disconnect the AC power harness by squeezing the locking arms on the sides of the quick connector while pulling the connector away from the bottom of the alarm.
Use thumb to pull deactivation tab outward until tab snaps into place. This will discharge the powercell and deactivate the unit.
You can silence the low battery warning “chirp” by pressing the Test/Silence button on the alarm cover.
Insert your override key (the one with the square top) and while turning the key, take a flathead screwdriver and insert it in the crack of the door and slowly pry it open. Another method is to lay your First Alert safe on the right-hand side and using the override key to open the door.
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.
Press the button on the face of the fire alarm to silence false alarms from cooking smoke or shower steam, as well as to test the alarm to ensure it is working. A blinking power light informs you the smoke detector is operational, while a low battery-alert lets you know when it is time to change the battery.
For most devices, find and hold the button on the front of the alarm, until the alarm stops, to reset the device. Or, find the button labeled "Silent" or "Hush" to disable an inactive alarm. Totally disable an alarm by disconnecting its wires.
IMPORTANT: Deactivation of the alarm is permanent. Once the alarm has been deactivated, it cannot be reactivated or mounted back onto the mounting plate and will no longer detect smoke or carbon monoxide.
We typically attribute smoke detector false alarms at night to one of two factors: low battery power and a drop in the home's air temperature, or an environmental factor such as high humidity, steam, or smoke particles in the air.
Hardwired smoke detectors can still beep even if there is no battery. Possibly the backup battery might have been activated and that can signal a problem. The backup battery may have run out and that is causing your hardwired smoke detector to chirp.
Bypassing a zone allows you to arm your system with certain protected areas intentionally unarmed or to access a protected area when the system is armed. To bypass a zone, enter your [security code] + [6] + [2-digit zone number]. To unbypass a zone, enter your [security code] + [1].
NOTE: An interior LED turns on for 30 seconds after the door is opened. The user preset code “159”. Please input the user code again if the yellow light flashes with three buzzer beeps. Turn the knob counter clockwise to close the door.
Chirping is typically caused by mounting issues, a low battery, or alarm end-of-life.
Low Battery or End-of-Life: This type of chirp indicates it is time to replace your smoke alarm's batteries or the smoke alarm itself. Refer to your smoke alarm's user manual for the specific beeps based on your alarm.
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.
When you are testing your Smoke Alarm, there are a number of reasons why the alarm might not sound: You may not be holding the test button down long enough. Try holding it down for up to 10 seconds (20 seconds on photoelectric models.) Your battery may not be installed properly or snapped all the way in place.
Disconnect all power sources (take out the battery, if it is a plug in alarm remove it from the outlet, and if it is hardwired alarm disconnect it from any wiring). Hold the test/silence button for 20 seconds. Reconnect all power sources (put the new battery in, plug back into the outlet...
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.
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.
