Pushing the Test/Reset button on the alarm will end the hush period. The "SMART HUSH" feature has the capability to temporarily desensitize the alarm circuit for up to 8 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm.
It will reset in eight minutes, given that the smoke and debris have dissipated. You can press the hush button repeatedly until the air is clean.
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.
In most cases, you can find the 'hush' button on the smoke detector's cover.
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.
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.
In the rare event that a nuisance alarm does occur, Kidde's Worry-Free Alarms have a hush button feature that will temporarily silence the smoke alarm if a non-emergency condition activates it. Simply push the button on the alarm to temporarily silence the system for about seven minutes.
Pressing the test/hush button simulates the effect of the smoke and/or heat and is therefore the best way to ensure the alarm is operating correctly. For interconnected smoke alarms, test one of the units by pressing the test/hush button for 10 seconds.
Even after the battery has died, the detector maintains a residual charge that will keep the chirp going for at least seven days. To get the device to stop chirping once the battery has been removed, you must drain this residual charge by holding the test button for 15 seconds.
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.
Low Batteries or Time to Replace
Smoke alarms generally have a lifespan of about 10 years. When they reach the end of their lifespan, smoke alarms may give off false alarms. If your detector is older than 10 years, replace it with a new one right away.
Excess moisture or humidity in your home can interfere with your smoke alarm's internal sensors, which leads to false alarms. You will realize that your fire alarm sounds randomly at night when the humidity levels are high.
Temporary Solution, Not Permanent: Hush Mode temporarily silences the alarm for a specific duration (usually around 7 minutes). It should not be used as a permanent solution. If false alarms persist, it may indicate an underlying issue with the smoke detector requiring attention.
Sometimes, smoke detectors will keep going off for no reason when they have reached the end of their life span. Fire alarms have a lifespan of about 10 years, after which they will need to be replaced. Smart smoke detectors can help eliminate some of the annoyances related to false alarms.
If you replaced the battery and it's still beeping, the smoke detector might have expired like milk. Smoke detectors have an expiration date. The sensitive equipment inside can only work reliably for so long, so if yours is beeping and its expiration date has passed (or will in a year or two), it's time to replace it.
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.
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.
Take the individual chirping unit down: After shutting off the circuit breaker, take the individual unit down, remove the battery backup (if it has one), then hold the test button down for 15 seconds. This should reset your alarm and stop the chirping.
In all First Alert® ONELINK® alarms, there are two silence features: Alarm Silence can quiet nuisance alarms for several minutes. Low Battery Silence can temporarily silence the low battery chirp for up to eight hours before replacing the battery.
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.
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.
