DESCRIPTION AND OPERATION 

The HB300W low voltage occupancy sensor is designed for automatic lighting control in high bay wet location applications. The 

HB300W sensor contains a passive infrared sensor (PIR) and is modular being made up of two parts, a Sensor Module and a Lens. 

Time delay and PIR sensitivity values are set using DIP switches.

INSTALLATION OVERVIEW

1.  Review the ADJUSTMENTS section and complete any 

necessary DIP switch setting changes. 

2.  Mount the sensor so the lens is below the edge of the 

fixture and away from the lamps. Heat from the lamps 

could affect the sensor operation. 
Make sure that you have the appropriate accessories for the sensor 

mounting configuration. (See MOUNTING OPTIONS.)

3.  Assemble any necessary mounting accessories and attach them to the 

sensor module. Make sure that the flying leads from the sensor module 

cable are accessible inside the fixture. 

4.  Connect the line voltage and load wires to the power pack leads as 

shown in the applicable Wiring Diagram for the sensor module.
•  Do not allow bare wire to show. 
•  Make sure all connections are secure.
•  Check all gaskets for watertight fit.

5.  Connect the low voltage wires from the power pack to the sensor.
6.  Check sensor operation. Refer to the TESTING section.
7.  Attach the Lens to the HB300W as shown in the sensor assembly 

drawing.
