SS4-AUV2 Multi-Spectrum Electro-Optical Digital Fire & Flame Detector, Aluminum UV, FM, Hydrocarbon & Non-Hydrocarbon Fires, indoor applications, Nonlatching Alarm LED, FM, cFM, CSFM for C1, D1, Groups B,C,D (2) 3/4 NPT by Honeywell Analytics

The Fire Sentry SS4 Electro-Optical Digital Fire and Flame Detectors represent leading edge UV and UV/IR technology.

Fire Sentry SS4-A

The Fire Sentry SS4-A represents the world's pre-eminent UV/IR technology for ElectroOptical 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 utilises real-time signal processing algorithms that are optimised 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 ruggedised solar-blind UV, "Quantum-Effect" IR and VIS sensors correspondingly. It is optimised 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. The SS4-AUV is for indoor applications where UV sources such as welding are not present.

Operation

The Fire Sentry SS4 detectors operate from standard 24 Volt DC power and interface to approved fire alarm panels or standard PLC's. On power up, 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 continuous spectral data stream of information from the sensor array is analysed by the microprocessor. 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 communicate with CM1-A Controller via a four wire bi-directional RS-485 FireBus™.

The field of view for the Fire Sentry SS4 detectors is the widest in the industry with a 120° cone of vision. This means more hazard area can be covered by each detector. Greater sensitivity also increases the volume covered by each detector; up to four times more than some other detectors.

Using sophisticated microprocessor signal processing algorithms, false alarm rejection is maximised - with virtual immunity to false alarms from arc welding, corona discharge and other common non-fire sources.
