Beam Detectors
Projected-beam smoke detectors for large, open, or high-ceiling spaces.
Overview
Beam detectors project an infrared beam across a large open area and detect smoke by the beam's attenuation, covering warehouses, atriums, and high-ceiling halls that would need many point detectors otherwise.

Adjustable sensitivity for high-ceiling or dusty environments
Applications
Warehouses and distribution centersAtriums and high-ceiling lobbiesSports halls and exhibition centersHeritage buildings where point detectors are impractical
