OVERVIEW
The SENSORWORX®wireless ceiling mount occupancy sensor is a simple, yet reliable
battery powered control solution. Preferred by contractors for their exible mounting
methods, SENSORWORX wireless sensors greatly reduce total installation time and
wireless pairing fuss. Requiring just a few seconds per device, SENSORWORX wireless
sensors can be linked to one or more wireless load controllers (such as the SWX-851
wireless wall switch, or a SWX-950 series wireless power pack). Additionally, these
sensors can be congured to work in applications with other wireless or wired ceiling,
corner, or hallway sensors to provide extended coverage in large or irregularly shaped
spaces. As with all SENSORWORX products, the latest passive infrared technology and
digital signal processing techniques are used to provide unmatched occupant detection
performance and energy savings.

DETAILED OPERATION
Ã By default, every ~60 seconds the sensor transmits whether or not occupancy was detected during the previous period.
Ã Referred to as the sensor’s “heartbeat”, this period can be reduced to ~30 seconds although this will decrease expected battery life.
Ã If a sensor transmitted “unoccupied” at its last heartbeat, any new occupancy detection event will be transmitted immediately.
Ã If a sensor transmitted “occupied” at its last heartbeat, new occupancy events will only be transmitted at the heartbeat interval, thus conserving battery life.
Ã The wirelessly linked wall switch load controller and/or power pack maintains a master time delay that is reset every time a linked sensor reports occupancy. Lights will be switched
off once all linked sensors have continously reported unoccupied for the duration of the time delay.
BASIC OPERATION
Sensors detect movement in the infrared energy that radiates from occupants as
they move within the device’s eld-of-view. Once occupancy is detected, the sensor
immediately signals a wirelessly linked load controller (e.g. power pack) to switch on or
dim up the connected lighting. At regular intervals, the sensor will retransmit its latest
occupancy status such that the load controller can keep lights on for occupants during
brief periods of inactivity, while returning the space to an energy saving lights off (or dim)
state once no longer occupied.

APPLICATIONS
SMALL SPACES
For control of small spaces like a private ofce, a single sensor linked to a wireless wall
switch controller (SWX-851) is recommended (see diagram on right). Linking additional
sensors is also an option if necessary. Switching from a second location (e.g. 3-way) is
achieved by linking a remote wireless wall switch to the wireless switch controller. Both
occupancy (auto-on) and vacancy (manual-on) operation are achievable in order to meet
energy code requirements.
Ã Small Ofces Ã Copy Rooms Ã Private Restrooms
LARGE SPACES
Multiple wireless sensors can be easily linked to a wireless power pack load controller
(SWX-950)to provide coverage for larger spaces (or larger loads) like an open ofce.
Additional functionality such as switching/dimming from multiple locations (e.g. 3-way)
or interfacing with wired control devices is achieved by linking to a wireless power pack
with appropriate functionality.
Ã Classrooms
Ã Open Areas
Ã Conference Rooms
Ã Hallways
Ã Break Rooms
SENSOR PLACEMENT
Typically, a sensor should be located such that all entrances to the room/space are adequately covered.
Ideally, a sensor should be located so that its coverage beams are perpendicular to the door. This ensures
that an occupant is detected immediately upon entering. See Diagram 1. Note, however, it is important to
locate a sensor such that its coverage pattern can not extend through an open door, which could result in
detection of persons walking by, but not into, a room.

INSTALLATION INSTRUCTIONS
MOUNTING OPTIONS
A. Chase nipple & lock nut (included) for mounting unit to ceiling tile or 1/2” knockout in
junction box. See Side Diagram below.
B. Screw holes for directly mounting to ceiling surface, 3-1/2” (trade size) octagon box, or
mud ring with 2-3/4” spaced ears. See Front Diagram below.
INSTALLATION NOTES
• If mounting to ceiling tile, use the serrated end of the chase nipple to cut a 7/8” hole.
Then thread the wires through nipple prior to screwing into rear of sensor. Install and
tighten lock nut as needed.
• To install cover, line up dimples with indents on sensor and turn clockwise.

Ã The sensor runs on one CR123(A) Lithium Battery (included).
Ã Install battery prior to mounting sensor. Polarity is indicated on the battery
compartment door.
Ã If the sensor’s battery life reaches 10%, all wirelessly linked load controllers will
blink lights on/off/on upon initial occupancy as a replacement warning.
Ã Replacement batteries are available at most retailers or home centers where
batteries are sold or from SENSORWORX.

WIRELESS LINKING (PAIRING)
Linking a sensor with a wireless load controller is quickly done via the following procedure:
Step 1. Enter pairing mode by holding down the wireless load controller button for 3 seconds until the LED starts alternating white then blue, then release.
Step 2. At the sensor, hold down the programming button for 3 seconds until the LED starts alternating white then blue. Releasing will link the sensor with any device in pairing mode
(see note 1 below). The lights will toggle once as conrmation.
Step 3. Repeat step 2 to link another sensor or device.
Step 4. When all devices have been linked, exit pairing mode on the wireless load controller by pressing the button 1 time. Pairing will also be automatically closed
after 15 minutes of no new devices being linked.
Note 1: When in pairing mode, the alternating LED colors on the wireless load controller will periodically pause and blink out the total number of linked devices. There will be no blinks
during the pause until the rst device is linked.

CONFIGURATION
SENSOR HEARTBEAT TIME
The period between transmissions of a wireless sensor is referred to as the sensor’s “heartbeat”. For best battery life performance, it is recommended that the default heartbeat time of
1 minute be used. However, if a linked load controller is using the 30 second time delay option, the sensor’s heartbeat needs to also be changed to 30 seconds. Note that doing so will
decrease battery life.

3 1 Minute (Default)
CHANGING THE HEARTBEAT TIME
1Read through the above list and note the number of the desired setting (e.g. 2 = 30 secs.)
2Press and release the unit’s pushbutton 3 times, then wait 2 seconds.The White LED will blink back the number of the current setting (repeats 3x before exiting).
3Interrupt blink back by pressing the button the number times equal to the new desired setting (e.g. 2 = 30 secs).
4The LED will blink back the new setting number as conrmation and will be saved after three conrmations. After the third conrmation sequence, a successful save will be indicated by
two sets of rapid White ashes. If the Blue LED rapid ashes twice, save was unsuccessful and process should be started over.

TESTING & TROUBLESHOOTING
COVERAGE TEST MODE
To put a sensor in COVERAGE test mode for 10 minutes:
1. Press and release the button two times.
2. Once the LED blinks white, press and release the button one additional time.
3. The LED will blink back white three times and then rapid ash twice indicating the change to test mode was sucessful.
To test coverage, wait until lights turn off then walk into range of sensor. While in test mode the LED will blink when it transmits an occupied signal (maximum of once every 4 seconds).
After 10 minutes, the unit will automatically exit test mode.
Note: Once test mode has been inititated from a linked sensor, the linked controller will ignore all other sensors until a new sensor initiates test mode or the 10 minutes expires.
TESTING WIRELESS LINKING (PAIRING)
1. Press and release the button one time.
Lighting controlled by any/all linked load controller(s) will toggle one time as conrmation.
