The HD105 is designed for single station use. Small and compact, the design and color makes it ideal for use in the home, small commercial properties, and recreational vehicles. It is intended to detect leakage of natural gas (methane gas), town gas, and bottled gas (propane gas). The unit is designed for DC wire in applications. The gas alarm can be mounted high (for methane gas) or low (for propane (LPG) gas).

It is equipped with a sturdy metal mounting bracket for quick, easy, and secure installation.

For detecting natural gas (lighter than air), the HD105 should be installed below the ceiling and the maximum distance away from the furnace or gas appliances is 8 meters.

For detecting LPG (heavier than air), the HD105 should be installed the maximum distance away from the furnace or gas appliances is 4 meters.
