6.0 Mounting Location
Hydrogen is colorless and odorless; the lightest of all gases and thus rises. The hydrogen
sensor, therefore, should be installed at the highest, draft-free location in the battery
compartment, cabinet, or room where hydrogen gas would accumulate.
The Alarm Box can be mounted at eye level or wherever is convenient for the user.
The size of the area one sensor will protect depends upon the battery compartment or room.
The detector measures hydrogen gas concentration in the air immediately surrounding the
sensor. Hydrogen gas may accumulate in several areas of the battery compartment or room
therefore; individual detectors should be installed in each of these areas.
