Long Range retro-reflector and mounting template
(1) If not already in place, stick the retro-reflector cut-out template to the outside of the duct
wall opposite the Transmitter/Receiver.
Ensure that point X is directly opposite point X on the mounting plate template. This
ensures that the Transmitter’s beam hits the centre of the retro-reflector.
(2) Drill six mounting holes (7mm diameter) in the positions marked J on the template.
(3) Following outline K, cut a square aperture in the duct wall.
(4) Insert the two retro-reflector panel support bars through the aperture and attach them to the inside
of the duct.
Check that the threaded holes in the support bars line up with the holes drilled in the
duct. Use M6 nuts and washers.
(5) Fit four M6 x 16 cap head screws into the holes in the support strips leaving approximately
5mm of thread exposed on the outside of the duct.
(6) Slot the retro-reflector assembly over the heads of the screws and allow its weight to be
supported on the exposed sections of thread.
(7) Tighten the four screws to clamp the retro-reflector assembly in position.
