Alarm Action

If the alarm is sounding, press the test/reset button to terminate the alarm.

  • If the alarm sounds again within 24 hours,
    • Contact a heating professional to check the detector and your appliances.
  • If the unit alarms again within six minutes, it is sensing high levels of CO which can quickly become a dangerous situation. 
    • Immediately move to fresh air - outdoors or by an open door/window.
    • Do a head count to check that all persons are accounted for.
    • Call 911 to report the condition.
    • Do not re-enter the premises until the emergency service responders have arrived, the premises have been aired out, and your alarm remains in its normal condition.
