Ceiling Vacancy-Occupancy Sensor
3. Remove the ceiling tile from the T-bar frame.
4. Insert the wire staples through the pinholes on
the sensor, one set located on each side near the
keyholes.
5. Poke the tines through the ceiling tile, then
bend each tine over in opposite directions for a
secure fit.
6. Replace the ceiling tile and reattach the sensor
cover.
Wallboard Ceiling
1. Insert a flatblade screwdriver under one of the two release tabs and
gently pry to remove the cover and access the mounting keyholes.
2. Mark the location of the keyholes on the ceiling.
3. Bore two holes and insert the anchors (not provided).
4. Attach the sensor to the ceiling with the screws (not provided).
5. Replace the sensor cover.
Integrated Magnets
Attach sensor directly to the suspended ceiling steel T-bar frame or other
metallic surface using the two integrated magnets.
Double-sided Tape or Velcro
1. Cut two lengths of tape (not provided) to the appropriate size and
adhere one side to the mounting plate and the other to the ceiling.
2. Press the sensor firmly in place.
Sensing Technology
PIR sensing is calibrated to detect motion in the human body heat range.
The lens divides the viewing angle into zones to detect when infrared
energy moves in and out of a zone.
The amount of movement that the sensor detects depends on the density
of the zones and where the motion takes place. A high density of zones
means smaller motions are detected. The movement zones in lens A are
designed to detect small motion (typing, desktop activity). See
Coverage on
Audio sensing filters out background noise level averaged over a
30 second window and sets its threshold slightly higher. If sound exceeds
the threshold while the timers are active, the sensor's occupied state is
maintained. For example, if a fan is running in the background of an
occupied space, only a sound slightly louder than the fan registers.
