Motion/Occupancy Sensor
Performance and Applications
For any FlexStat model with a (passive infrared) motion/occupancy sen-
sor option, be sure to install it where it will have an unobstructed view
of the most typical trac area. Do not install it behind curtains or
other obstructions. Do not install it where it will be exposed to sun-
light or heat sources! Do not install near a heating/cooling duct.
For some applications, such as hotel rooms, bedrooms, and other
sleeping quarters, lack of detected motion may not truly mean “unoc-
cupied.” Motion sensors coupled with door contacts can prevent such
undesired setbacks. If no motion is detected during a predetermined
time after a door opening/closing is detected, then the mode changes
to unoccupied. However, if motion is detected during the timed period
after a door has been opened/closed, then occupied mode shall remain
on until the next time a door is opened or closed (and the timed period
begins again). (Custom programming is required.)
The eective detection range is approximately 10 meters or 33 feet.
Factors that may reduce the range include:
• Too small of a dierence in object surface temperature compared to
the background temperature.
• Object movement in a direct line toward the sensor.
• Very slow or very fast object movement.
• Obstructions.
False detections may be triggered by:
• The temperature inside the detection range changing suddenly
because of entry of cold or warm air from an air-conditioning or
heating unit.
• The sensor being directly exposed to sunlight, an incandescent
light, or other source of far infrared rays.
• Small animal movement.
NOTE: To maintain maximum
sensitivity, occasion-
ally wipe dust or dirt
o the lens—but do
not use any uid on
the sensor.
