Warnings:
This detector is added protection, not a substitute, for prudent safety measures where
hydrogen gas is present. For large or highly sensitive areas, you may have to use two or
more detectors with 1 or 2 sensors each for increased detection.
The hydrogen sensor does not provide protection from fires or hydrogen explosions.
The relay contacts are intended to be connected to a safety system, enabling audible
alarms, system shutdown, ventilation, or other measures to ensure safe handling and
use of hydrogen gas.
Ensure that your installation complies completely with all relevant local, State, Federal,
and OSHA safety and health regulations
If sensor responds, there is a risk of combustion or explosion. To avoid injury leave area
immediately.
The hydrogen sensor is calibrated for operation in air. Tampering with the sensor or
operation in other gas environments can lead to inaccurate readings and possible
permanent damage if operating in a reducing atmosphere or 100% hydrogen. The
hydrogen sensor is silicone resistant but uncured silicone compounds or extended
exposure to silicone off gassing, or high concentrations of refrigerant gasses related to a
leak, can give inaccurate readings in the sensor.
