Honeywell SS4-A Flame Detector

The Honeywell SS4-A MultiSpectrum Flame 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 Honeywell SS4-A 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 Honeywell SS4 Detectors’ FireLogic signal processing requires that UV, visible and WideBand IR radiant energy all be evaluated before declaring a fire. The Honeywell SS4-A Flame 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.

The Honeywell SS4-A Flame Detector operates from standard 24 Volt DC power and interfaces to approved fire alarm panels or standard PLC’s. When power is applied, a self-test is performed and the fault relay resets to show no faults. The front LED lights flash every 10 seconds to indicate power is on.
