The Honeywell SS2 Fire Sentry Flame Detector sense radiant energy in the ultraviolet (UV), visible and WideBand Infrared (IR) spectrum. The radiant energy from all types of flaming fires will alert the detectors to their presence.

The field of view for the Fire Sentry SS2 Flame Detector is the widest in the industry with a 120° cone of vision. This means each detector can cover more hazard area. Greater sensitivity also increases the volume covered by each detector, up to four times more than some other detectors.

The Fire Sentry SS2-AM and Fire Sentry SS2-AML are the ultra-high speed digital Multi-Spectrum optical models of the Fire Sentry SS2 UV/IR flame detectors. These detectors feature ultra-high speed responses to explosive fires and are typically used in munitions production, explosives production and special applications.

Applications for the Fire Sentry SS2-AM and SS2-AML include:

  • Munitions Production
  • Explosives production
  • Manufacturing of other explosive materials
  • Silane & hydrogen gas storage
  • Special applications
