4. Locate the 2-point AC In terminal strip (see Figure 1). The terminals
are labelled LINE and NEUT.
5. Guide the AC power cord or wires through the right-most conduit hub
on the bottom of the Beacon 200 housing.
CAUTION: Do not route power and detector head wiring through the same
conduit hub. The power wiring may disrupt the transmission of
the detector head signal to the monitor.

strip as shown in Figure 6.
7. Connect the ground wire to the unused crimp terminal that is factory
installed at the base of the ground stud.
a. Remove all installed connections (from conduit hubs and power
supply).
b. Remove the bottom lug.
c. Crimp the ground wire to the lug.
d. Reinstall the lug.
e. Reinstall all of the other ground connections (from conduit hubs and
power supply).
WARNING: Follow this grounding procedure to maintain the CSA
classification of the Beacon 200.
