The MLB/WPRO500C should be installed within the height range 2.0m to 2.5m.
(See Fig. 2).
The unit has an adjustable lens with two detection zones.
• The outer zone covers an angle of 240º to a distance of approx. 3m to 16m at an
installation height of 2.3m. (See Fig. 3).
• The inner zone covers an angle of 360º which allows detection immediately
behind the MLB/WPRO500C. (See Fig.4).
• Fig. 4 also shows the variation of sensitivity with angle of approach for a person
moving within the detection area.

A Installation Procedure
a. Read the instruction manual before installing the MLB/WPRO500C.
b. Make sure the mains power supply has been disconnected.
c. Decide the best location to install the unit bearing in mind the most sensitive
direction of movement shown in Fig. 4.
Then ensure that the top of the fl oodlight is no closer than 200mm to the surface
above it and it is no closer than 500mm to the surface at the side of it.
(See Fig. 6).
Also ensure that any surface directly illuminated by the fl oodlight is at least 1m
away from the front glass. (See Fig. 8).
Do not mount the unit base on a horizontal surface such as a soffi t,
(See Fig. 7) or on an infl ammable surface such as wood or plastic.
