    76-M-6010-02-02 1. Introduction The F-Guard-IR3-H2 flame detector will detect hydrogen and other “energy transition” fires quickly allowing actions to be initiated to minimize the extend of the fire. The detector addresses slow growing fires as well as fast eruptions of fire using improved IR3 technology. The detector operates in all weather and light conditions.
