This smoke alarm responds best to fast-raging fires. The Test/Reset button function tests alarm circuitry, alarm activation, and peak level memory. It features visual indicators for alarm and power-on, and provides alarm function during a power outage. Voice warning announces "Fire," "Carbon Monoxide," or "Low Battery." Adjustable smoke sensitivity helps reduce nuisance alarms. Easy installation.
