Wireless Ceiling Mount
Occupancy Sensors

SWX-200-B SERIES
Battery Powered

Overview

The SENSORWORX® wireless ceiling mount occupancy sensor is a simple, yet reliable battery powered control solution. Preferred by contractors for their flexible 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 configured 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.

 

Basic Operations

Sensors detect movement in the infrared energy that radiates from occupants as they move within the device’s field-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 office, 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.

 

  • Small Offices
  • Copy Rooms
  • 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 office. 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.

Coverage

Small Motion 360° – Passive Infrared (PIR)

  • Excellent detection of small motions from sitting or stationary occupants (e.g. hand motions).

  • 8 to 12 ft (2.44 to 4.57 m) mounting height recommended.

  • ~500 ft2 of coverage

  • Line of site between occupant and sensor is required for detection.

  • Sensor can not see through glass windows or doors.

  • Detection range improves when walking across beams as compared to into beams.

  • Spaces with small temperature differential between occupants and ambient may encounter reduced sensitivity/range.

 

Battery Information

  • The sensor runs on one CR123(A) Lithium Battery (included).
  • Install battery prior to mounting sensor. Polarity is indicated on the battery compartment door.
  • 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.
  • Replacement batteries are available at most retailers or home centers where batteries are sold or from SENSORWORX.

Operation Notes

  • By default, every ~60 seconds the sensor transmits whether or not occupancy was detected during the previous period.

  • Referred to as the sensor’s “heartbeat”, this period can be reduced to ~30 seconds although this will decrease expected battery life.

  • If a sensor transmitted “unoccupied” at its last heartbeat, any new occupancy detection event will be transmitted immediately.

  • If a sensor transmitted “occupied” at its last heartbeat, new occupancy events will only be transmitted at the heartbeat interval, thus conserving battery life.

  • 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 continuously reported unoccupied for the duration of the time delay.

Installation Options

Wireless Linking (Pairing)

Linking a sensor with a wireless wall switch controller or power pack load controller is quickly done via the following procedure:

Step 1. Enter pairing mode by holding down the wireless load controller’s 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 confirmation.

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 first device is linked.
