• Do not restrict the air flow to the unit housing.
• Do not mount the unit in a corner.
• Do not mount the unit near containers of chemicals such as gasoline, kerosene, alcohol,
or other cleaning fluids. High level concentrations of these chemicals may be mistaken
as the target gas by the sensor and cause false readings. Also, some welding gases
may cause false readings.
The detector is attached in the mounting position in one of two ways.
• Attach the housing to a four inch conduit box using the conduit fittings supplied with the
detector. If you use this method, make sure that the four inch box is securely attached
with screws to a solid support base. Firmly tighten the threaded nuts on the conduit
fittings inside the conduit box so they will not loosen over time.
• Attach the housing to a solid support base using screws through the holes in the
mounting feet.
Find a flat area at least 8 inches high by 11 inches long and place the back of the open
housing flat against it. Using a pencil or other slender marking tool, mark the location of
the four mounting holes using the housing as a template. Start the screws without the
housing in place to avoid any possibility of damage to the housing or circuit boards.
Remove the screws, place the housing in position, and install the mounting screws. Do
not over-tighten the screws as this may crack the plastic housing.
Connecting the Power Supply
Brasch Gas Detectors are designed to operate from either 120 VAC or 24 VAC. Selection of
the operating voltage is made by the user at the time the detector is ordered. The correct
voltage is listed on the label in the lower, left corner of the front panel.
While this detector does not require much power to operate, it is usually located near
machines that do consume large amounts of power. When these large machines operate, they
cause large voltage spikes to appear on the AC wiring. These spikes can interfere with the
proper operation of the detector. The easiest way to avoid much of this interference is by
