Double Infrared and Ultraviolet Flame Detector
1.General Description:
The JTH-CH386Ex explosion-proof point type infrared / ultraviolet flame detector contains
two infrared wavelength sensors,one ultraviolet sensor and optical filter. The detector has
the highest sensitivity to the CO2 emission spectrum (4.4 mu m). The infrared sensor
detects the interference of ambient light and heat radiation.
2.Product function and composition
It detects the Ultraviolet produced by fire,combines with the flame flicker frequency to process
multiple signals ,which can maximum restrain the false alarm and the optimal fire detection
perfermance,improve the sensitivity and response time of the detector.Make it has the
performance of Antisun interference.
The flame detector not only has early warning performance for organic compounds and other
organic materials, but also for inorganic fire. According to customer demand, the detector can be
set as infrared, ultraviolet and relationship, infrared, ultraviolet or relationship.
The JTH-CH386Ex explosion-proof point type infrared / UV flame detector can work in harsh
industrial environments such as high temperature, low temperature, high humidity and vibration.
With the remote control detection function, the detector can be used to simulate the fire alarm
function, the alarm reset, the setting of the delay alarm, and the setting of the lock and the
unlocked mode of the relay output.
