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 unobstructed view of
the most typical trac area. Do not install it behind curtains or other
obstructions. Do not install it where it will be exposed to sunlight 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 aer a door opening/closing is detected, then the mode changes
to unoccupied. However, if motion is detected during the timed period
aer 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 eective detection range is approximately 10 meters or 33 feet.
Factors that may reduce the range include:
• Too small of a dierence 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, occasionally
wipe dust or dirt o
the lens—but do not
use any uid on the
sensor.
