Product overview
The detector AW-FD707EX combines the latest ultraviolet and dual infrared detection technologies to provide fast, accurate and reliable fire detection, and the patented signal processing algorithm can eliminate false alarm to against wrong light sources, which means it applies to most environment places (Refinery, Loading Rack and Aerosol Fill etc).
The UVIR2 flame detector uses a new narrow-band current infrared pyroelectric sensor and the R2868 "sunlight blind" ultraviolet photoelectric sensor with a built-in 32-bit microprocessor and patented composite signal processing algorithm.
Product Features
  • Extended detection range
  • Adjustable high sensitivity
  • More Flexible and Compatible
  • Easy Installation
  • Reliable fault diagnosis
  • Built-in high-speed, low-power,
  • high-performance 32-bit high-precision data processing chip.
  • The detector is suitable for a variety of fuels
  • Suitable for heavy industrial applications
  • Low maintenance cost, easy to update and improve
  • A small fire can be detected earlier.
