PIR MOTION DETECTOR
INTRODUCTION
The PIR-2S Passive Infrared Detector is specially designed for providing space protection in a wireless
security system. It detects the movement of human body heat within its effective coverage; thus when an
intruder crosses or enters the area, the resulting change in infrared energy from the intruder will be detected
and an alarm signal will transmit to the Base Unit.
IMPORTANT NOTE
To get the best sensitivity, PIR should be mounted to detect movement of the
intruder "across" room, rather than "toward" the detector.
Do not install where the detector faces a window, since movement outside could
cause unwanted alarms.
Make sure the detection area does not have obstructions (curtains, screens, large
pieces of furniture, plants, etc.) that could block the pattern of coverage.
Avoid placing the sensor in areas containing objects likely to produce a rapid
change in temperature, such as central heating radiators or ducts (or heaters of
any kind), air conditioners, open flame, etc.
Note that pets can trip sensors and plan sensor placement and pet-restricted
areas accordingly.
INSTALLATION
1.
Remove the front cover by holding the base in one hand, and squeezing the top center of back cover
