1. Scope
1.1 Product Overview
The Spectrex Model 20/20R Single IR Flame Detector provides early warning of
flaming fires involving organic (hydrocarbon fuels and vapours) materials. These
fires emit strong IR radiation in the 4.4-micron spectral band where the CO
2
(main
combustion product of any organic substance) has a unique spectral peak.
This detector contains a “state-of-the-art” infrared sensor and optical filter that
provides maximum sensitivity to the CO
2
emission spectral band at 4.4 micron.
The detector withstands “harsh” environmental conditions, including extreme
temperature, high humidity, vibrations, etc.
