PRECAUTIONS
1. Precautions on Installation
2. Other Precautions
[Vertical installation]
[Horizontal installation]
●
Install the unit in such a direction that people are
more likely to cross the detection zones.
◎For horizontal installation,
do not instll in a site which
is subject to rainfall.
◎Cover screw should be
downward.
●
The unit should be installed as the following.
●
In case of outdoor installation, adjust the lens holder
to 2°, 4°, 6°downward from horizontal.
●
Do not install the unit by an air conditioning
exhaust vent.
Remove all obstructions (trees, clotheslines, etc.)
●
Check the detection zones before operation.
(Unexpected objects may be detected.)
●
Install in a site which avoid direct sunlight.
If not, use the lter. (See below)
●
Do not install in a site
which is subject to
electrical noise or
vibration.
●
Remove obstructions, including glasses, from the
detection zones.
●
Avoid using the unit for primary security purpose.
(The unit is designed to detect infrared energy
variation caused by a human body.
Therefore, similar variations in conditions due to
other reasons, may cause the sensor to output a
signal as it is unable to distinguish between the
sources.)
●
Insert the lter between the lens and the lens holder
when using the unit in a site which is subject to
direct sunlight.
●
The lter reduces inuence
of sunlight.
(This also lowers the
sensitivity.)
Check the sensitivity by a
walk test.
