Ceiling-Mount Occupancy/Vacancy Sensor
• PIR sensing must have an unobstructed view of the space. Do not
mount behind or near tall cabinets, shelves, or hanging light fixtures.
• Avoid locating the sensor where it can easily sense movement outside
of the intended space, such as hallways, glass partitions, or adjacent
rooms. If these conditions are unavoidable, use lens mask stickers to
block off specific areas. See
• Do not install within eight feet of an HVAC airflow duct or vent.
Installation
The sensor can be attached to a suspended ceiling or finished wallboard
ceiling. An auxiliary mounting plate with integrated magnets is also
provided. Determine the installation method and follow the instructions.
Integrated Magnets
Attach sensor directly to the suspended ceiling steel T-bar frame or other
metallic surface using the auxiliary mounting plate's integrated magnets.
Double-sided Tape or Velcro™ (not provided)
Cut two lengths of tape to the appropriate size and adhere one side to the
mounting plate and the other to the ceiling. Press firmly in place.
Wire Staples to Ceiling Tile
1. Remove the sensor cover to gain access to the mounting pinholes.
2. Mark the sensor mounting location on the ceiling tile.
3. Remove the ceiling tile from the T-bar frame.
4. Insert the wire staples (provided) 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. Remove the sensor cover to gain access to 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.
Sensor Operation
The sensor's six solar cells harvest and store solar energy from natural or
artificial light sources and provide sufficient power to operate without a
battery up to seven days for the DT models, and nine days for the PIR. It can
