Overview

The HEF-KIT consists of a dual-relay Hydrogen Gas Detector and a Hydrogen Exhaust Fan. The Hydrogen Gas Detector monitors hydrogen gas and provides warning of increasing levels before they become dangerous. Should the concentration of hydrogen gas in the air surrounding the sensor reach 1% by volume, the yellow caution LED will light and the 1% internal relay will close. Should the hydrogen gas concentration reach 2% by volume, the red warning LED will flash and an 80 decibel alarm will sound; the 1% relay will remain closed and the 2% internal relay will close. The 1% relay will activate the Hydrogen Exhaust Fan for forced ventilation.
