FireSentry SS4-A
The FireSentry SS4-A is a multispectral detector that senses ultraviolet (UV),
Flame radiation energy of the visible and broadband infraredTM (IR) spectrums. The detector can detect a wide range of types
The flame radiation energy.
To eliminate those who are using single-frequency ultraviolet (UV), single-frequency infrared (IR), and ultraviolet/infrared (UV/
IR) flame detector often occurs and falsely alarms, Fire Sentry SS4detector will warn of fire
UV, visible, and wideband IR radiation energies were previously evaluated by FireLogic signal processing.
This intelligent detector is optimized with real-time signal processing algorithms to detect all types of fires
Alarm response, which can basically eliminate the possibility of false alarm.
Fire Sentry SS4-AS
The Fire Sentry SS4-AS uses a durable day-blind UV sensor, "quantum effect" type IR and VIS
Sensors that can handle a range of spectrums including ultraviolet, infrared, and visible light (VIS). It has a negative impact on hydrogen
The detection of gas, ethanol, methanol and methane (natural gas) flames has been optimized to allow him to detect all types of fires
Flame response.
Fire Sentry SS4-AUV
The Fire Sentry SS4-AUV is an outstanding representative of ultraviolet (UV) optical flame detectors. The flame
The detector senses the radiation energy in the ultraviolet (UV) spectrum to detect if a flame is emitting
Radiant energy.
