• White, contemporary style that blends unobtrusively when mounted on walls or ceilings 

Sensor & Detection

• Equipped with a photoelectric sensor, optimized to detect larger smoke particles from slow-burning, smoldering fires (e.g. cigarette or couch fires).

• Includes an endoflife signal to notify when detector should be replaced after ten years 

Audible & User Interface

• Features a single test/silence button for easy testing or silencing of false alarms 

Installation & Mounting
