FireSentry SS4-A
The Fire Sentry SS4-A represents the world’s pre-eminent UV/IR technology for
Electro-Optical Flame Detectors with tens of thousands successfully operating in
a multitude of installations worldwide. This multi-spectrum detector senses radiant
energy in the ultraviolet (UV), visible and Wide Band Infrared™ (IR) spectrum. The
radiant energy from all types of flaming fires will alert the detector to their presence.
To eliminate common nuisance false alarms that occasionally occur with
UV-only, IR-only, Dual IR or Dual Mode UV/IR detectors, the Fire Sentry SS4
detectors’ FireLogic signal processing requires that UV, visible and Wide
Band IR radiant energy all be evaluated before declaring a fire. The smart
detector utilizes real-time signal processing algorithms that are optimized
to alarm on all types of fires, while virtually eliminating the possibility of
false alarms.
Fire Sentry SS4-AS
The Fire Sentry SS4-AS processes UV, IR and Visible (VIS) spectral ranges from
ruggedized solar-blind UV, “Quantum-Effect” IR and VIS sensors correspondingly.
It is optimized for detection of hydrogen, ethanol, methanol and methane (natural
gas) fires and like the other detectors in its family, it responds to Type A, B and C
flaming fires.
Fire Sentry SS4-AUV
The Fire Sentry SS4-AUV represents the leading edge technology UV optical
flame detectors. This flame detector senses radiant energy in the ultraviolet (UV)
spectrum. The radiant emissions of flaming fires will alert the detector to
their presence.
