2-wire Fixtureless Sensors

Besides using the ‘Enlighted 2-wire’ SU-5S (High Bay and Ruggedized) sensors for connecting to drivers in fixture lighting control applications, you can also use the following types of sensors in installations where the sensor is NOT connected to any fixture drivers or ballasts (Fixtureless sensors).

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.   

You can order Fixtureless sensors of the 2-wire, High Bay, and Ruggedized sensor (SU-5S) with the product code suffix -FL for fixtureless. In this special version, Enlighted has factory disabled the DALI bus communication. The fixtureless sensors can be used in installations where no fixture is connected to it, or additional data collection coverage is needed.

1. High Bay Sensor, 2-wire, (SU-5S-2W-H-FL) 
2. Ruggedized Sensor, 2-wire, (SU-5S-2W-xRx-FL)

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:  

1. 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. 
2. No polarity dependence. 

Install Solutions:

There are three available options for fixtureless sensors, depending on the form factor needed:

1. High Bay Sensor: Order SU-5S-2W-H. Note that this solution is NOT polarity sensitive.
2. Ruggedized Sensor:  Order SU-5S-2W-xRx-FL.  Note that this solution is NOT polarity sensitive.
3. Micro Sensor:  Order SU-5E plus CBL-5E-PWR-30N.  Note that this solution IS polarity sensitive.

1. 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).  

2. 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).

3. Micro Sensor (SU-5E) plus Power Cable (CBL-5E-PWR-30N)

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:

1. SU-5E, 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.
2. SU-5E Sensor Grid with BZ-50 Power Pack (03129-04) for Micro sensor with Power cable (CBL-5E-PWR-30N); Polarity is critical.
