SS4-A2 / AS2
The SS4 is a hazardous area certified flame detector for the detection of hydrocarbon (SS4-A2) and non‑hydrocarbon fires (SS4-AS2). This multispectrum detector senses radiant energy in the ultraviolet (UV), visible and wideband infrared (IR) spectrum. The radiant energy from all types of flaming fires will alert the detector to their presence. The field of view is the widest in the industry with 120° field of view with a range of 60 ft. This means more hazard can be covered by each detector.
Features
• Multi-Spectrum™: senses ultraviolet, visible and Wide Band Infrared™
• Built-in test for optical “through the lens” testing
• False alarm immunity
• Detects hydrocarbon and non‑hydrocarbon based fires
• Wide field-of-view and solar-blind
• Adjustable detector sensitivity
• Microprocessor based algorithms: FirePic™, Snapshot™ and Tri-Mode Plot™
• Wide temperature range of operation
• Compatible with standard approved fire alarm panels
• Explosion-proof housing
• Time programmable alarm verification
• FM, ATEX mark approvals
SS4-AUV2
While retaining all the features of the standard SS4-A2, the SS4-AS2 is optimized for the detection of ethanol, methanol, hydrogen and natural gas with a range up to 60 ft. range and a field of view of 120°, the UV only Version, SS4-AUV2, is for indoor applications where UV sources such as welding are not present.
