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.
These features, along with a built-in event logger, provide additional means to study the cause and
development of fire events.
The detector is certified for use in hazardous area locations; it may also be used in other areas not
classified as hazardous. The two cable/conduit entries either side of the lower part of the detector
housing are for connecting power and outputs to associated signaling equipment.
During normal operation, the flame detector performs self-tests of its optics, electronics, and software.
These include a periodic BIT (Built-In-Test) in which the sensors and window cleanliness are tested.
