Flame detector ALMAZ


Flame detector ALMAZ is designed to detect flame coming from sources of fire and accompanied by ultraviolet (UV) radiation in the wavelength range from 220 to 280 nm.

Detector is used in structure of automated fire detection systems together with alarm control or alarm actuating devices, that provide power supply voltage 12-30 V in the line of fire alarm.

There are 2 modifications of the detector present:

  1. general modification for installation in premises of various buildings and structures, also installation of the detector is possible outdoors under a canopy (for example, to protect gas stations, oil depots, and so on).
  2. explosion-proof modification for installation in explosion dangerous places (for example on factories, mines, chemicals warehouses, others).

Detector uses modern indicator of ultra-violet radiation as a flame sensor. This creates immunity of the device to sunlight, light from incandescent lamps and fluorescent lamps.

The spectral sensitivity range of the flame detector

On this graph you can see that a narrow spectral sensitivity region of the detector does not intersect with the relative characteristics of sunlight and tungsten light. Therefore, in contrast to similar flame detectors working on converting the infrared (IR) spectrum of light, the installation of the Detector ALMAZ can be realized anywhere in the protected premises, including, in front of windows or in the immediate vicinity of the lighting fixtures. Also the detector does not react to sources of heat radiation.

Moreover, at this distance the unit detects a flame created by the combustion of petroleum products as well as various alcohols, coal, wood, synthetic fibers, plastics, textile, rubber, pulp and paper products, paints and etc.

Autonomous audible warning system of fire (flame) on the territory of the petrol station

 audible warning system for gas station Audible alarm unit

A loud signal of this System can warn the staff and customers about outbreak of flame or fire in the territory of the petrol station. The system consists of several flame detectors and audible alarm unit (with sound volume is 90 ... 100 dB) and power supply (car battery of voltage = 12V). Flame detectors are installed at gas stations so that to provide control over the entire territory of the gas station
