Fixtureless sensors are used for collecting data for Enlighted applications, such as Location Intelligence for indoor location and mapping for asset tracking. They provide increased sensor density and coverage in a facility, improving location-based accuracy. Fixtureless sensors are NOT used for controlling lights in a site, and hence are not connected to any fixture drivers or ballasts.
The following Gen-5/-6, 2-wire sensors are categorized as Fixtureless sensors because they do not control lighting. These sensors have -FL (Fixtureless) suffix in their product code. In this special version, Enlighted has factory disabled the DALI bus communication.
- Micro Sensor, 2-wire, (SU-6E-2W-FL)
- High Bay Sensor, 2-wire, (SU-5S-2W-H-FL)
- Ruggedized Sensor, 2-wire, (SU-5S-2W-xRx-FL)
- Micro Sensor (SU-5E) and Power cable (CBL-5E-PWR-30N)
The sensors will be shipped with an -FL Fixtureless yellow label around the sensor's wires; remove the label before installing the fixtureless sensors.

Be sure to install -FL sensors in the following conditions ONLY,
- When NO fixture is connected to that sensor, and
- ALWAYS when multiple sensors (up to 15) are connected to a single PSU or power pack.
Benefits:
The advantage of using the 2-wire, High Bay, or Ruggedized sensors as fixtureless include:
- Simplified wiring and reduced cost: Up to 15 sensors can be connected to a single 200mA DALI PSU (PSU-4-200 or PSU-6-200) or power pack.
- No polarity dependence.
Install Solutions:
There are four available options for fixtureless sensors, depending on the form factor needed:
1. Micro Sensor SU-6E, 2-Wire, Fixtureless (SU-5E-2W-FL)
The SU-6E-2W sensor belongs to Gen 6 sensor family and delivers all the functionality of Gen 5 microsensors in a minimally sized package that is functionally identical to the Micro Sensor with 2-wire Adaptor (KIT-SU-5E-D) - Spec Sheet minus the 2-wire adapter cable. Refer to the line diagram SU-5S, 2-wire, Sensor Grid with DALI Power Supply (03227-03). This solution is NOT polarity sensitive.
2. High Bay Sensor, 2-wire, Fixtureless (SU-5S-2W-H-FL)
You can connect up to 15 High Bay, 2-wire, fixtureless sensors with a user-supplied solid 18AWG, two-conductor cable to a 200mA DALI PSU. A maximum of 500' of the cable may be connected to a single power supply. Polarity is not critical. Refer to the line diagram SU-5S, 2-wire, Sensor Grid with DALI Power Supply (03227-03). This solution is NOT polarity sensitive.
3. Ruggedized Sensor, 2-wire, Fixtureless (SU-5S-2W-LRW/HRW-FL)
You can connect up to 15 Ruggedized, 2-wire, fixtureless sensors with a user-supplied solid 18AWG two-conductor 500' cable to a 200mA DALI PSU. A maximum of 500' of the cable may be connected to a single power supply. Polarity is not critical. Refer to the line diagram SU-5S, 2-wire, Sensor Grid with DALI Power Supply (03227-03). This solution is NOT polarity sensitive.
4. Micro Sensor (SU-5E) plus Power Cable (CBL-5E-PWR-30N)
Note that this solution IS polarity sensitive, The Micro Sensor (SU-5E ) and Power cable (CBL-5E-PWR-30N) fixtureless solution is 'polarity' dependent, and hence, wiring becomes critical, which can be error-prone. Use extreme caution when wiring these sensors. Refer to the line diagram SU-5S, 2-wire, Sensor Grid with DALI Power Supply (03227-03).
Power Cable (CBL-5E-PWR-30N)
You can connect up to 15 Micro sensors, 2-wire (KIT-SU-5E-D), with the power cable to a DALI PSU. Each SU-5E sensor will require one sensor cable (CBL-5E-PWR-30N); Part Number: 12-02769-01
Note that when this cable is connected to a SU-5E Sensor, the polarity is critical. The sensor will not work unless all +/-ve connections are correct. The power supply's positive terminal must connect to the Red wire, and the negative terminal connects to the Black wire.
- 30-inch Power Cable, (CBL-5E-PWR-30N)

Refer to the following line diagrams:
- SU-5S, 2-wire, Sensor Grid with DALI Power Supply (03227-03) for the Micro sensor, 8-pin with Power cable (CBL-5E-PWR-30N); Polarity is critical.
- SU-5E Sensor Grid with BZ-50 Power Pack (03129-04) for Micro sensor with Power cable (CBL-5E-PWR-30N); Polarity is critical.
