1. Precautions on Installation
•
Install the unit at the height of 2.6' to 4.0' from the ground.
•
Install the unit horizontally so that its horizontal zone is
parallel to the ground.
•
Install the unit in such a direction that people are more
likely to cross the detection zone.
2. Other Precautions
•
Operation LED blinks for about 1 min after turning on power.
During this warm up period, the sensor doesn't make
detection.
•
Day light switch allows this unit to issue an alarm signal only
when the surrounding area is darker than set illuminance.
In other words, if surrounding area is brighter than set
illuminance, this sensor doesn't output signal.
•
This sensor operates during detecting time + delay time set by
a potentiometer.
It continues to issue alarm as long as it detects objects
regardless of set delay time.
•
Do not pour water on this unit with a hose as it is designed to
be rainproof, not waterproof.
•
When detection mode is set at AND mode, this sensor outputs
alarm signal only when both upper and lower sensor detect
objects.
In other words, it won't make detection in the area, which is
not covered by both upper and lower sensor.
[Only applicable to MS-12FE]
2.6'~4.0' (0.8~1.2m)
•
Do not install the unit by
an air conditioning exhaust
vent.
•
Remove all obstacles (including clear glass), which will
create non detection zone.
Non detection area
•
Make sure that downward zone will not be affected by sun
light reflected by water on the road etc.
