Mounting the DU3 detector unit
Determine where the detector unit will be mounted on the outside wall of the building. (See Figure 3.)
NOTE:
Be certain there is an available AC electrical outlet near the mounting site, on the wall inside the
drive-thru service area.
!
Drill a ½ inch (13mm) hole through the wall at the
location where the detector unit will be mounted.
!
Hold the unit centered over the hole, against the
outside wall, and mark the wall through the four
holes at the corners of the unit.
!
Drill four ¼ inch (6mm) screw holes at the
marked spots, deep enough to insert the
enclosed screw anchors.
!
Insert the enclosed screw anchors completely
into the four screw holes.
!
Route the 12 ft. (3.66 meter) cables from the
back of the detector unit through the ½ inch
(13mm) center hole.
!
Hold the detector unit with the arrow on its top-
front pointing up (Figure 4), and the screw holes
at its four corners over the screw anchors on the
wall. Push any slack cable back through the
center hole into the building.
!
Screw the four enclosed screws through the
screw holes in the detector unit (Figure 4)
and into the screw anchors, to fasten the unit
securely to the outside wall.
