How to stop a nuisance or false smoke alarm from Kidde

So you got your smoke alarm but it wont stop chirping or is giving a false alarm. There are a few reasons on why your smoke alarm may be chirping or giving a false alarm. Below are some tips from Kidde on how to effectively stop nuisance or false alarms. Based on what type of smoke alarm you have Kidde has tips on what to do.

1. Temporarily silence your alarm:

Sometimes you may have to temporarily silence your alarm. For example; if you cooked some thing and you caused smoke you can temporarily silence the alarm by pushing the test/hush button. 

  • 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.

  • The smoke alarm will automatically reset after approximately 8 minutes and sound the alarm if 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.

2.) Clean and reset your smoke alarm:

Dust can easily make your alarm go off. So you will want to dust your alarms and reset your smoke alarms when needed. Below are some tips from Kidde.

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:

  • To find the initiating unit, look for one that is flashing RED 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, please see the owner’s manual to see if the alarm model has a memory to tell you which unit was initiating.

  • 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 vacuum out the gap between the front cover and the back plate all the way around the perimeter with the crevice tool attachment of a vacuum cleaner, or blow through the same gap with compressed air.

Resetting a hardwired unit with a removable battery backup:

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

  • Turn off the power to the smoke alarm at the circuit breaker.

  • 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.

  • Reconnect the power and reinstall the battery. 

  • NOTE: The unit will chirp once when the power is restored, and 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.
