1 Overview
Dual-band infrared light detection for fire alarm.
Sensitive to flame from material containing carbon. Suitable for fire happen with
flame at the start.
Addressable (connecting GST fire alarm control panel) and non-addressable
(through relay contact) working modes optional.
Flame-proof. Applicable to either commercial or hazardous industrial areas, such
as explosive Zone 1 and 2, and flammable dust atmosphere.
