How to temporarily silence your alarms:

DO NOT USE THIS FEATURE IF A FIRE IS PRESENT. ONLY USE THIS FEATURE AFTER YOU HAVE CONFIRMED THERE IS NO DANGER.


The Hush® feature of most alarms provides the capability to temporarily lower the sensitivity of the smoke sensor for up to 10 minutes. This feature should be used only when a known alarm condition, such as smoke or heat from cooking, activates the alarm.


  • For hardwired or wireless alarms, only hushing the initiating unit will silence all other interconnected alarms (see below on how to find the initiating unit).

  • The smoke alarm is desensitized by pushing the “Test/Hush” button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately. If the smoke or debris is interfering with the sensor, the alarm will override the Hush.

  • 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.

How to clean and reset your alarms:

If you have hardwired alarms, the first step is finding the initiating unit, as that is the key to stopping all of the interconnected units from sounding:


  • To find the initiating unit, look for one that is flashing RED or GREEN at least once every second while in alarm mode, then follow the reset procedure on that unit. 

  • If the alarm stopped on its own before you could find that flashing light, the initiating unit will flash for 1.5 seconds every 10 seconds.

  • If there are no obvious signs of a fire, the alarm should be cleaned before being reinstalled. False alarms are most commonly caused by something interfering with the sensor.

  • To clean, after disconnecting the alarm and removing any removable battery: hold the unit by its edge and thoroughly blow through the gap on the side of the unit with compressed air (like keyboard cleaner).

Resetting a hardwired unit with a removable battery backup

To reset a hardwired unit with a battery backup, perform the following steps:


  • Remove the smoke alarm from the mounting bracket and disconnect the power.

  • Remove the battery (for a sealed-battery model, see Battery Settings for a 10-Year Alarm to learn more).

  • Press and hold the test button for five seconds.

  • Reconnect the power and reinstall the battery. NOTE: The unit will chirp once when the power is restored, but should not chirp afterwards.

 

Resetting a removable battery-only unit

To reset a battery only unit, perform the following steps:


  • Remove the battery (for a sealed-battery model, consult your user guide).

  • Press and hold the test button

  • Reinstall the battery. NOTE: The unit will chirp when the battery is first connected, but should not chirp afterwards.
