Ajax EN54 Fire Detection (Smoke/Sounder) Black

€154.00
  • The unique smoke chamber, dual-spectrum optical sensor, and proprietary HazeFlow 2 software algorithm guarantee the speed and accuracy of fire detection.
  • The smoke chamber is hardwired with a dual-spectrum optical sensor that has blue and infrared LEDs with different wavelengths. It measures the microparticle concentration in the air to determine the size of the volatile particles inside the chamber and responds only to smoke.
  • The HazeFlow 2 algorithm analyses and compares data from the dual-spectrum optical sensor to a specified pattern to define smoke from vapor or steam. The detector instantly raises the alarm when pattern dynamics indicate a real case of fire.
