Using the Silence Feature

The Silence Feature
This feature is intended to temporarily silence the horn while you identify and correct the problem. Do not

Silence Feature can temporarily quiet an unwanted alarm for several minutes. You can silence this Smoke/
CO Alarm by pressing the Test/Silence button on the alarm cover for at least 3-5 seconds or via the
Onelink app. After the Test/Silence button is released, the Red LED stops during the silence mode.
