Overview
SENSORWORX digital wide view and hallway occupancy sensors deliver excellent detection and are simple to install. In particular, their flexible mounting styles and multiple methods of digital pairing to other devices reduce contractor time greatly. Additionally, these sensors can be utlized with other ceiling, corner, or hallway sensors to provide extended coverage in large or irregularly shaped spaces. All SENSORWORX products are proudly made in the USA.
The SENSORWORX digital suite of products communicate over a topology-free, 3-wire data line connection. Wiring uses common 18/3 cable & wire nuts, thus eliminating the issues that plague CAT-5 based systems. These individually addressable sensors are digitally zoned together with load controllers and wall stations via one of three methods. The first is the out-of-the-box single zone default configuration, the second (for multi-zone applications) is by using a push-button pairing sequence, and the third is via the SENSORWORX mobile application (also requires SWD-940 Advanced Load Controller). Once paired, a digital control zone can be highly configured with several operating modes, dimming settings, and photocell parameters.
As with all SENSORWORX products, the latest PIR (passive infrared) technology and signal processing techniques are used to provide unmatched occupant detection performance and energy savings. Additionally, units are available with an integrated microphone to provide overlapping passive acoustic detection for rooms where occupant motion is limited or where there are obstructions. An integrated daylight harvesting photocell is also an available option.
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 paired load controller to switch on or dim up the connected lighting. If equipped with passive dual technology (PIR/Acoustic), the unit’s microphone is then also enabled to further enhance detection while the lights are on. At regular intervals, the sensor retransmits 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
A single SENSORWORX digital wide view sensor provides an excellent solution for a medium sized space like a conference room or small classroom. However, multiple sensors can be easily paired to the same load controller(s) to provide coverage for larger spaces like an open office or large classroom. Dual Technology sensors are recommended in spaces where people are seated and/or where obstructions like cubicle walls block line of site to the sensors. The SENSORWORX digital hallway sensor provides excellent coverage of hallways from one or both ends.
Additionally, when paired to SENSORWORX digital load controllers (such as the SWD-900 Load Controller or SWD-940 Advanced Load Controller) and remote digital wall stations, these sensors can be used to meet ASHRAE 90.1, IECC, & Title 24 energy code requirements that require vacancy operation.

Coverage Patterns
WIDE VIEW 120°
PASSIVE INFRARED (PIR)
- Small motion (e.g., hand movements) detection up to 40 ft (12.19 m)
- Large motion (e.g., walking) detection up to 70 ft (21.34 m)
- Designed for 8 to 12 ft (2.44 to 3.66 m) high mounting
Diagram reflects sensor in first position. Adjust angle downward if mounting above 10 feet or to decrease gap directly under sensor.
HALLWAY (LONG RANGE)
- Designed for 8 to 12 ft (2.44 to 3.66 m) high mounting
- Large motion (e.g., walking) detection up to 100 ft (30.48 m)
- Detection occurs sooner when crossing coverage beams upon entry to a hallway as opposed to entering from the end and walking directly at the sensor
Dual Technology (PIR/Acoustic)
- Units with dual technology (SWD-421) have overlapping acoustic detection of the complete PIR coverage area.
- A PIR event is required to initially enable acoustic detection.
- Sounds indicating occupancy reset the sensor’s time delay while non-occupant noises are filtered out. Occupant sounds alone will not keep lights on indefinitely, PIR motion must be periodically detected for lights to remain on for an extended time.
- After sensor time out expires, acoustic detection remains enabled for 15 seconds to enable voice reactivation of lights for additional convenience and safety.

Digital Zone Configuration
A. Out-of-the-Box (single zone only)
B. Push-Button Pairing (required for multi-zone)
C. Mobile App Pairing (requires a SWD-940 on digital data line)
A. OUT-OF-THE-BOX FUNCTIONALITY
By default, digital load controllers listen to all devices connected via the data line. This enables installers to immediately verify all device wiring, and provides instant control of single zone rooms. Default listening is cancelled once the first device is paired via method below.
B. PUSH-BUTTON PAIRING (SEE DIAGRAM BELOW)
Step 1. Enter pairing mode by holding down the button on the load controller to be linked for 3 seconds until the LED starts alternating white then blue.
Step 2. At the sensor, hold down the button for 3 seconds until the LED starts alternating white then blue. Upon release the load controller will be paired (i.e. linked) to the sensor. The lights will toggle once as confirmation.
Step 3. Repeat step 2 to link additional sensors or remote devices.
Step 4. When all devices have been linked, exit pairing mode on the load controller by pressing its button 1 time. Exiting will also occur automatically after 15 minutes of no new devices being linked.
Note 1: When in pairing mode, the alternating LED colors on the 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 via the push-button (or mobile app.) pairing process.
Note 2: Once the first remote device has been paired to the load controller it will stop listening to all non-paired devices on the data line.
MOBILE APP PAIRING
Note: Requires a SWD-940 Advanced Load Controller be on the same data line as the sensor.
Operation Notes
-
If a sensor transmitted “unoccupied” at its last heartbeat, any new PIR detection event will be transmitted immediately.
-
Using the information received from paired sensors, digitally paired load controllers switch lighting accordingly.
-
All load controllers have a master time delay that is initially set only when a PIR occupancy transmission is received from a paired sensor. The time delay will then be reset every time a sensor reports any occupancy (either PIR or acoustic). Lights will be switched off once all paired sensors have continuously reported unoccupied for the duration of the time delay.
-
To prevent lights from staying on indefinitely from just acoustic events, after ~30 minutes the load controller will stop considering acoustic events from all paired sensors until after a PIR event is received again.
-
As an added safety measure after lights are switched off, acoustic detection remains enabled for 15 seconds to enable voice reactivation of lights.
-
If a load controller does not receive any heartbeat transmissions from a paired sensor for 10 minutes it will blink out an error code (4 blue blinks, followed by a pause) and consider itself occupied (so as to override the lights on). If more than one sensor is paired, the sensor heartbeats from all sensors must have stopped for the error warning to begin blinking.
