C To Avoid Nuisance Triggering
7
Your motion sensor may be activated by animals, light refl ective surfaces, heat
sources, or movement of objects. The following guidelines will help you avoid
nuisance triggering.
• Do not aim the sensor toward lights of any kind. (See Fig. 16, 17). Aim the sensor
and light in a different direction.

Fig. 17
• Avoid aiming the sensor towards objects which may move in the wind, such as
bushes. (See Fig. 18).
• Avoid mounting the sensor near heat sources, such as heating vents, air
conditioners, dryer vents or lights. (See Fig. 19).
• Avoid directing the sensor toward areas or objects whose surfaces are highly
refl ective such as pools or are subject to rapid temperature change.

c. The Adjustment of LUX, METER and TIME
The MLB/WPRO500C has three adjustable knobs, LUX, METER and TIME on the
underside of the sensor head.
• The LUX knob can be set to allow the MLB/WPRO500C to operate at any light
level between full daylight and almost complete darkness.
• The METER knob reduces the forward PIR range from around 16m to around 3m.
• The TIME knob can adjust the time (a period between 6 seconds and
approximately 12 minutes) for the light to remain "ON" after the last detection.
