Pressing the hush button on the smoke alarm will cause the smoke alarm to beep or chirp for 10-15 minutes. The Hush feature is designed to desensitize the smoke alarm from false alarms, with the chirping indicating hush mode is active. Hush mode will automatically reset once the 10-15 minute chirping cycle is over.
Once the designated time of seven minutes has gone by, the smoke detector will reset itself completely. It will stop the chirping noises and the alarm will automatically return to its original state.
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.
After ten (10) years of cumulative power up, this unit will “chirp” two times every 30 seconds. This is an “operational end of life” feature which will indicate that it is time to replace the alarm. To help identify the date to replace the unit, a label has been affixed to the side of the alarm.
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.
Hush mode will silence the smoke alarms for a period of 9 minutes. If the alarm's sensor is still detecting particles after the Hush period ends, the alarms will initiate again. You can keep using the Hush function until contaminants have cleared the air.
In addition, it can take days for a battery to completely drain, and the chirping will continue throughout that time. How long does it take a smoke alarm to stop chirping? An alarm will continue to chirp for at least seven days after its battery has died.
It sounds like your Kidde alarms are reaching the end of their useful life. Most smoke and carbon monoxide alarms are designed to last around 7-10 years, and once they reach that age, they often start malfunctioning or go off continuously as a signal they need to be replaced.
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.
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.
Kidde recommends replacing all smoke alarms - battery and hardwired - every 10 years. If your alarms are older or you don't know their age, you should replace them. CO alarms will sound a required "end-of-life" chirp after seven to ten years of power. Beat the beep by replacing outdated alarms.
Do Not Disturb, the Ring/Silent switch and Silent mode don't affect the alarm sound. If you use the Ring/Silent switch or Action button to turn on Silent mode or turn on Do Not Disturb, the alarm still sounds.
One reason that the alarm is going off all the time could be simple: It needs a new battery as soon as possible. Batteries ought to be replaced annually, so it is worth getting into the habit of changing them on a regular basis. Unless, of course, it has a sealed battery which should last up to 10 years.
Your alarm will indicate end of life seven or ten years after initial power. It will 'chirp' every 30 seconds. The chirp will not stop until the unit is powered off. You'll know that it is an end-of-life warning and not a low battery warning because replacing the batteries will not stop the chirp.
The "HUSH" feature has the capability to temporarily desensitize the smoke alarm circuit for approximately 7 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. The smoke alarm is desensitized by pushing the "HUSH" button on the smoke alarm cover.
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.
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.
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.)
The HUSH feature can be used repeatedly until the air has been cleared of the condition causing the alarm. While the unit is in HUSH mode, pushing the test/reset button on the alarm will also end the HUSH period.
Debris such as dust or soot often produced by burning matter can accumulate on the gadget thereby triggering the alarm even when there is no actual fire. Dust or other unwanted particles can interfere with the alarm sensors which will affect their normal functioning.
If the smoke alarms give three beeps, then nothing, or any other kind of consistent but spaced-out chirps, there are two possible malfunctions: the device or the battery. If your alarm beeps once every minute for five minutes, this generally means it might be at the end of the device's life.
Clear Residual Charge to Stop the Chirp
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.
All your fire alarms might be going off because of low batteries, dust or insects inside the alarms, steam or humidity, or a malfunction. Try resetting them, replacing the batteries, and cleaning the alarms. If they keep going off, you might need to replace old alarms or check for wiring issues.
