End Hush Period (if needed): Sometimes, you can end it before it automatically resets. You can do this by pressing the test/reset button on the smoke detector. It is useful if the situation causing the false alarm has been resolved before the preset hush time elapses.
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.)
If it still doesn't operate properly call the Product Support Line at 1-800-880-6788. The HUSH feature has the capability of temporarily desensitizing the smoke alarm circuit for approximately 9 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm.
Stopping a smoke alarm from beeping is often simple. Get a step ladder and carefully reach for the alarm. 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.
Silence the Alarm in 3 Steps
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.
Reasons why a smoke alarm keeps beeping include: The smoke detector's battery has not been installed properly or may be loose. The sensing chamber of the smoke detector may be dirty. Environmental factors like humidity or heat may set off an alarm.
It will if the smoke detector is not hard wired. If it is hard wired and it is (erroneously) in alarm, turn off the circuit breaker and remove the battery, and replace the unit.
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.
Common reasons a fire alarms keeps going off are: Dead or dying batteries. Poor placement, like in kitchens, bathrooms or garages. Interference from airborne chemical compounds, like those released from wet paint.
Manually pressing and holding the “silence” button on the smoke detector/fire alarm will cause it to stop sounding but not permanently turn it off. On older models, you may need to unscrew the alarm from the wall or ceiling and hold down a button on the back.
Remove the power source from your alarm to fully deactivate it. If your alarm does not have a silence button, or if you need it off for a significant amount of time, try removing its power source. Twist your alarm counter-clockwise, then pull it off the mounted base.
You may also be able to hit the silence button on any smoke alarm, which will cause all the non-initiating smoke alarms to silence so you can hear just the initiating one.
The smoke alarm will automatically reset after approximately 8 minutes unless particles of combustion are still present. The “Hush” feature can be used repeatedly until the air has been cleared of the condition causing the alarm. Pushing the Test/Hush button on the alarm will end the hush period.
Hush Mode: A Temporary Measure
For example, if you know that the smoke detector is overly sensitive, and will always be triggered when you use oil with a high smoke point in the kitchen, then you can hit the hush mode to desensitize and the detector for about seven minutes, during which the alarm will be silent.
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.
Pushing the Test/Hush button on the alarm will end the temporarily desensitized period. Model P3010B will issue a voice prompt stating “Hush Mode Cancelled” after the Test/Hush button has been pressed. If the smoke is not too dense, after ten minutes the alarm will return to normal operation.
Turn the power supply off at the source and completely power down the system. Then, wait up to a minute to turn it back on. A common cause of beeping is low batteries. If any component of your system operates on batteries, replace them and then reset the alarm to allow the system to register the new batteries.
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.
Remove the AC power to the home alarm console from the wall directly. Use your console's access key (or another item such as a small screw) to unlock and open the system's backing. Lastly, disconnect at least one of the wires that are attached to the system's main battery, which is blocky and noticeable in most units.
