The Honeywell 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 SS4 Flame Detectors’ FireLogic signal processing requires that UV, visible and Wide Band IR radiant energy all be evaluated before declaring a fire. The smart detector utilises real-time signal processing algorithms that are optimised to alarm on all types of fires, while virtually eliminating the possibility of false alarms.

Honeywell Analytics SS4-AS:
-
The Honeywell SS4-AS processes UV, IR and Visible (VIS) spectral ranges from ruggedized solar-blind UV, “Quantum-Effect” IR and VIS sensors correspondingly. It is optimised for the 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.
Honeywell Analytics SS4-AUV:
-
The Honeywell 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.
