How do I reduce the sensitivity of my smoke detector?
Lessen the sensitivity of the smoke detector by removing it from an area of air high velocity that can trigger an alarm. Areas of high air velocity include, for example, outside a bathroom door where steam vapor can exit during a shower, or an overly close proximity to the cooking smoke coming from an oven.
Why does my fire alarm go off randomly at night?
