surface with screws. Securely tighten the fitting nut on the inside of the conduit box so it
will not loosen over time.

Attach the housing to a solid support base using screws through the internal housing
mounting holes. This method requires removal of the housing cover to gain access to
the mounting holes. A mounting hole is located at the top and bottom of each housing
end wall.
Find a flat area at least 6 inches high by 6 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. Be careful not to
damage the printed circuit board. Carefully replace the housing cover and securely
tighten all four of the cover retaining screws.
Connecting the Power Supply
While this control panel 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 control panel or transmitters. The easiest way to avoid much of this
interference is by providing power to the system through a dedicated circuit from the service
panel. In some very noisy situations, a line filter can be connected in the power supply circuit
just ahead of the wiring connections at the panel.

WARNING
This detector may require the use of voltage levels high enough to cause fatal injuries.
Proper procedures must be followed any time work is performed on this unit.
Only qualified personnel should attempt to install, maintain, or service this equipment.
Note
Do not operate the detector on the same AC circuit as the ventilation components. Doing
this will almost always cause improper operation.
