First you can hush your alarm by pressing on the pause/hush button. It will pause the alarm for 10 minutes to allow you to find the reason of this, and to locate the source of the alarm. Humidity, dust particles or small insects in the smoke chamber can cause false alarms; this can be solved by vacuuming the mesh and drying the smoke alarm. You may need to relocate your smoke alarm if it is too close to the kitchen, bathroom, air condition units or any other source of humidity.
