Occupancy Sensor - Ceiling Mounted
Package Contents
▪ Occupancy Sensor
▪ 2 screws, 2 wall anchors
▪ Wire bracket
Product Description
The ceiling-mounted Occupancy Sensor saves energy and adds
convenience by accurately detecting when an area is occupied
or vacant.
This device is wireless, powered by indoor light, and uses a passive infrared (PIR) sensor to detect motion. The occupancy sensor transmits RF signals that control lighting, HVAC and outlets
to manage energy more efciently.
Features Include:
▪ Sends wireless messages to other devices whenever motion
is detected
▪ Harvests ambient solar energy to power the sensor and wire-
less communication
▪ Mounts easily on any ceiling material
▪ Works with other sensors for enhanced occupancy tracking
▪ Built-in tests to conrm operation at installed location
▪ Supplemental battery or alternative power supply options for
extreme low-light conditions
Tools Required
▪ Power drill, 3/16” bit
▪ Screwdriver
▪ Light meter
▪ Battery (CR2032) for testing

Functional Description
If occupation is detected by the permanently active PIR sensor,
a radio telegram indicating the occupied status will transmit
immediately. An internal timer starts to run with a variable timer
length. The timer value may vary between 60 and 300 seconds,
depending on the light level. No radio telegrams will be sent
out when the timer is counting down.
After the timer has nished the countdown, the unit will transmit again if occupancy was detected during the countdown time
period. If occupancy was not detected, the unit will transmit a
heartbeat signal - sending the unoccupied status with a random timing of 2 to 12 minutes. There are two buttons which
allow entrance to a “Walk” or “Light-level” test mode. These
test modes are for installation purposes only and will be exited
automatically after 3 minutes.

Occupancy Sensor – Ceiling Mounted • Installation Guide
Planning
Take a moment to plan for the sensor’s successful operation and
optimal communication with other system components.
Remove the sensor from its packaging and place it under a
bright light to provide the required startup charge. To quickly
ensure the sensor energy storage is fully charged, insert a
CR2032 battery for 5 minutes.
▪ Ensure the location provides consistent and adequate light
▪ Install with the appropriate lens for the required coverage
▪ Avoid installed near ceiling fan or hanging xtures
▪ Consider the area’s trafc patterns and principal use, for
example, walking, working, lounging or sleeping
▪ Provide a minimum clearance of 4 ft. (1.2 m) away from heat
sources, light bulbs, forced air, or ventilation systems
▪ Consider the construction materials (such as metal) in the
space and obstacles that may interfere with RF signals
Sensor Range
A single occupancy sensor provides sufcient coverage for most
applications. For some applications, multiple sensors may be
required to provide complete coverage.
Coverage Diagrams
Installing
The occupancy sensor can be mounted on most ceilings with
the provided screws, or mounted on dropped ceilings, using the
provided wire bracket.
NOTE: It may be easier to link the sensor before it is mounted
on the ceiling. Refer to the “Linking” section.
1. Decide where you want to install the occupancy sensor.
Tip: For visual alignment, orient the sensor parallel to one of
the walls.
2. Remove the mounting plate from the sensor.
3. Decide which of the two installation options is appropriate.
A. Screw Mounting Plate to the Ceiling
i. Hold the mounting plate in place on the ceiling and
use a pencil to lightly mark two small dots for the
screw drill points.
ii. Drill two holes with a 3/16” drill bit and insert
the wall anchors.
iii. Insert the rst screw
loosely and level the
mounting plate.
iv. Insert the second screw
and then hand-tighten
the rst screw.
estimated time: 20 minutes
To provide coverage for very high ceilings, a wall sensor can be
incorporating in the plan for complete coverage.
B. Mount Using the Wire Bracket
i. Remove the ceiling tile where you want to
mount the sensor.
ii. Place the mounting plate squarely on the ceiling tile
and use the wire to mark two points for the holes.
iii. Punch two small holes
through the ceiling tile at
the marked points.
iv. Insert the wire bracket
through the two holes in
the mounting plate.
Make sure the ends are
roughly even.
v. Feed the wires through the
holes in the ceiling tile.
vi. On the front of the ceiling
tile, atten the wire bracket
so it is snug against the
mounting plate.
