Spectron-401.01-Exd-H fire flame detector

The detector is an ultraviolet (UV) flame detector. The detector is designed for use in hazardous areas of enclosed spaces, as well as in underground workings of mines, mines and their above-ground structures. The design of the device and the scheme of the sensor location allows to obtain the resulting diagram of detection of ignition sources in the form of a 100° cone. The signal "FIRE" is formed only when the UV sensor registers the presence of flame.
detector detects the presence of flame. The standard configuration of the detector includes an "FIRE" signal relay and a "FAULT" signal optorelay. The detector is equipped with a self-diagnostic function of internal circuits with a fault signal transmission to the alarm loop.
Heating system allows the detector to operate in the temperature range from minus 70ºC to plus 90ºC (+135 short-term). Spektron-401.01-Exd-H is a special version and has a short response time required for instantaneous signal "FIRE".
