Wireless Wall Switch
Load Controller

SWX-851 SERIES
LINE POWERED

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 significantly shallower than typical dimmers, 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.

Applications

SMALL SPACES
For control of small spaces like a private office, a wireless wall switch controller linked to 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.

  • Private Office
  • Copy Rooms
  • Private Restrooms

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 soltion. 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.

  • Small Classrooms
  • Conference Rooms
  • Short Hallways
  • Break Rooms

Code Compliance

These load controllers can be used to

energy code requirements.

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 white then blue, then release.

Step 2. At the sensor (or other remote device), hold down the programming button for 3 seconds until the LED starts alternating white then blue. 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 first 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 first (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.

Wiring Diagrams

  • Unit works both in installations where Neutral connection is available as well as installations where only Ground connection is present.

  • If no neutral is present, remove the white sleeve from the wire & connect the now Green/Yellow wire to Ground.

  • Note, either the white wire or green/yellow wire must be connected. The all green wire is just for safety.

Basic Wiring

Neutral to Ground Conversion Detail

  • The white wire has a removable sleeve which reveals a green/yellow wire
