The Fire Sentry SS4 Electro-Optical Digital Fire and Flame Detectors represent leading-edge UV and UV/IR technology.
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 many 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 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 utilises real-time signal processing algorithms that are optimised to alarm on all types of fires while eliminating the possibility of false alarms.
Fire Sentry SS4-AS
The Fire Sentry SS4-AS processes UV, IR and Visible (VIS) spectral ranges from ruggedised solar-blind UV, “Quantum-Effect” IR and VIS sensors correspondingly.
It is optimised for detecting fires in hydrogen, ethanol, methanol, and methane (natural gas). 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.
Operation
The Fire Sentry SS4 detectors operate from standard 24 Volt DC power and interface to approved fire alarm panels or standard PLCs. When power is applied, a self-test is performed, and the fault relay resets to show no faults.
The front LED lights flash every ten seconds to indicate power is on. The microprocessor analyses the continuous spectral data stream of information from the sensor array. Upon alarm, the detector activates the alarm relay and stores all the pre-fire spectral data in non-volatile memory for retrieval and evaluation. This Fire Pic™ data can be used to postulate the cause of the fire.
As part of the FS2000 System, the SS4 family of detectors communicates with the CM1-A Controller via a four-wire bi-directional RS-485 FireBus.
