SWX-851-xx WIRELESS WALL SWITCH LOAD CONTROLLER,
120/277VAC, NO NEUTRAL REQUIRED
BASIC OPERATION
A received wireless message indicating occupancy from one or more wirelessly linked
sensors will trigger the unit’s integrated relay to close. When congured for Vacancy
operation, lights must be initially switched on by pressing the unit’s button (or by pressing
the ON button on a wirelessly linked wall station). Once closed, line voltage will ow
through the relay and turn on the connected lighting load. This wall switch load controller
maintains a master time delay that is reset every time a linked sensor reports occupancy.
Lights will be switched off once there hasn’t been an occupancy message reported for the
duration of the time delay.

OVERVIEW
The SENSORWORX wireless wall switch load controller links to remote occupancy
sensors and switches without low voltage wiring in order to provide automatic lighting
control. Designed with contractors in mind, the unit is signicantly shallower than typical
wall controllers, resulting in less crowded wall boxes. Additionally, versatile wiring
enables usage with or without a neutral connection and never requires a minimum load.
This switch also matches the SENSORWORX family of wall switch occupancy sensors
and 0-10V dimming wall switch sensors. All SENSORWORX products are proudly made
in the USA.

APPLICATIONS
SMALL SPACES
For control of small spaces like a private ofce, a wireless wall switch controller linked
to a single wireless ceiling sensor (SWX-201-B) is recommended (see diagram on right).
Both occupancy (auto-on) and vacancy (manual-on) operation are achievable in order to
meet energy code requirements.
MEDIUM SIZE SPACES
For control of medium size spaces like a conference room or small classroom, a wireless
wall switch controller linked to a single wireless wide view sensor (SWX-401-B) provides
an excellect solution. 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
(SWX-852) to the wireless switch controller.

The below chart lists the devices that can be used in a SENSORWORX wireless application. Note that sensors and remote switch & dimmer devices are transmit only devices and
therefore must be linked to a load controller for switching or dimming of lighting.
WIRELESS LINKING (PAIRING)
Linking a wall switch controller with a sensor, power pack, dimmer, or another wall switch controller is quickly done via the following procedure:
Step 1. Enter pairing mode by holding down the wall switch’s button for 3 seconds until the LED starts alternating blue and white, then release.
Step 2. At the sensor (or other remote device), hold down the programming button for 3 seconds until the LED starts alternating blue and white. Releasing will link the sensor with the
switch in pairing mode (see note 1 below).
Step 3. Repeat step 2 to link another sensor or device.
Step 4. When all devices have been linked, exit pairing mode on the wall switch controller by pressing the button 1 time. Pairing will also be automatically closed after 15 minutes of
no new devices being linked.
Note 1: Once a device(s) is linked, the alternating LED colors on the wall switch controller will periodically pause and blink out total number of linked devices. There will be no blinks
during the pause until after the rst device is linked.
Note 2: Pairing two wall switch controllers (or one wall switch controller and one wireless power pack) can be done by putting each device in pairing mode rst (i.e. Step 1 above) before
continuing to Step 2 for each device. After Step 2 has been completed for each device, continue to Step 3 for each device.

CONFIGURATION SETTINGS
FUNCTION #2 OCCUPANCY TIME DELAY
Unlike wired occupancy sensor systems, the time frame between when occupancy was detected last and connected lights turning off is a setting that is maintained in the load controller
and not the sensor itself. This arrangement enables the sensors to conserve battery life. See additional notes below for more information on wireless sensor communications to a load
controller.
SETTING # DESCRIPTION FUNCTION #
2 1 Min
3 5 Min
4 10 Min Default for all models
5 15 Min
6 20 Min
7 30 Min
CHANGING THE OCCUPANCY TIME DELAY
1Read through the above list and note the number of the desired setting (e.g. 4 = 10 minutes).
2Enter programming mode by pressing and holding the button for 6 seconds until the LED begins ashing blue only, then release.
3Enter Function #2: Occupancy Time Delay by tapping and releasing the unit’s pushbutton 2 times.
4The LED will blink back white the number of times equal to the current setting (e.g., 4 times for 10 minutes). Following a short pause, this blink back sequence will repeat (3x before
exiting). Interrupt blink back by pressing the button the number of times equal to the new desired setting (e.g. 5 = 15 minutes). The LED will blink back white the new setting number as
conrmation
6To Save and Exit programming mode, press and hold the button until blue LED changes to white, then release. The LED will then blink white twice as conrmation of success.
Note: To Exit without saving during any step, release button and wait until the unit double ashes blue.
ADDITIONAL NOTES ON OCCUPANCY TIME DELAY
à By default, every ~60 seconds wireless sensors transmit a status message whether or not occupancy was detected during the previous period.
à Referred to as the sensor’s “heartbeat”, this period can be reduced to ~30 seconds although this will decrease expected battery life.
à If a sensor transmitted “unoccupied” at its last heartbeat, any new occupancy detection event will be transmitted immediately.
à If a sensor transmitted “occupied” at its last heartbeat, new occupancy events will only be transmitted at the heartbeat interval, thus conserving battery life.
à All wirelessly linked wall switch load controllers and/or power packs have 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.
à If a wall switch load controller does not receive a heartbeat transmission from a linked sensor for 10 minutes it will blink out an error code (4 blue blinks, followed by a pause). If more
than one sensor is linked, the sensor heartbeats from all sensors must have stopped for the error warning to begin blinking.
All conguration settings for the wireless wall switch load controller are organized into several parameter functions with values that can be accessed and changed by pressing the unit’s
push-button and observing the LEDs feedback.
NOTE: A 5-10 second time delay sensor test mode
can be initiated from a sensor in order to test
coverage. Test mode will expire after 10 minutes.
SETTING # MODE DESCRIPTION
2 Vacancy Mode
Pressing the unit’s button (or an ON button push on a linked wireless switch) is required to initially turn lights on. Lights will turn off automatically if
the OCCUPANCY TIME DELAY (Function #2) expires between received occupied messages from a sensor. Lights can also be switched off manually
by pressing the unit’s button (or if an OFF button push on a linked wireless switch is received).
3Occupancy Mode (Override Off)
Lights come on automatically when an occupancy signal is received from a wirelessly linked sensor. Lights will turn off automatically if the
OCCUPANCY TIME DELAY (Function #2) expires between received occupied messages from a sensor. Lights can also be switched off manually by
pressing the unit’s button (or an OFF button push on a linked wireless switch is received). After being switched off manually, lights will not revert to
an Automatic On state (i.e. the must be manually switched back on).

Note: To Exit without saving during any step, release button and wait until the unit double ashes blue.
ADDITIONAL NOTES ON OPERATIONAL MODES
à When runnning in the default operating mode (Setting 3 - Occupancy Mode (Presentation), if the lights are manually switched off when there are still occupants in a space (to
show a presentation for example), the Automatic On operation will be disabled until the sensor time delay expires.
à In applications with wirelessly linked sensors, if the switch is pressed but no occupancy signal is ever received, the lights will come on for 1 minute and then shut off.
à When in Vacancy (Manual On) Mode (Setting #2), there is a 15 second “grace” period after the sensor times out when the sensor will switch lights back on automatically if
occupancy is detected. After 15 seconds the sensor will revert to vacancy (manual on) operation.
