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.

MOUNTING OPTIONS
The sensor is pre-set at the factory to meet the requirements of
most applications. Review this section if your application requires
changing factory pre-sets.
Sensor factory pre-sets are as follows (default settings are bold):
Factory Switch Settings (N/A = not applicable, no effect)
1 2 3 4 5 6 7 8 9 10
ON OFF OFF OFF OFF ON ON OFF N/A N/A
PIR Sensitivity (switches 1&2) .....................Normal
Time Delay (switches 3-7) ....................15 minutes
Override (switch 8) ....Occupancy control enabled
PIR Sensitivity (Switches 1-2)
The factory setting (Normal) is suitable for most applications, but
it may be necessary to adjust the PIR sensitivity if there is any
environmental interference causing false triggers or if sensitivity
needs to be increased for your particular application. Use DIP
switches 1 & 2 to adjust sensitivity.
Switch 1 2 PIR SENSITIVITY
OFF OFF High
ON OFF NORMAL
OFF ON Medium
ON ON Low
Time Delay (Switches 3-7)
Use DIP switches 3 to 7 to adjust the time delay.
Switch 3 4 5 6 7 TIME DELAY
ON ON ON ON ON 15 seconds
OFF ON ON ON ON 5 minutes
OFF OFF ON ON ON 10 minutes
OFF OFF OFF ON ON 15 minutes
OFF OFF OFF OFF ON 20 minutes
OFF OFF OFF OFF OFF 30 minutes
Override (Switch 8)
The override disables the occupancy control feature of the HB300W
sensor module. When occupancy control is disabled, the load
remains ON as long as the sensor is powered.

Punch or drill a 0.825” (21 mm) hole in the luminaire housing
from the exterior of the fixture assembly of the standard
module. The wiring cable is threaded through it and into the
fixture for connection. Hand tighten with a threaded nut.
As shown in the illustration below, the HB300W can be
attached directly to a watertight fixture or junction box that is
equipped with a threaded nipple. The center of the threaded
nipple should be no more than approximately one inch (1”)
from the bottom of the fixture to avoid blocking the sensor’s
view.

The HBEM3W extender module allows attaching the sensor to
the side of the fixture so that the lens can be positioned below
the bottom edge of the fixture. The two sides of the HBEM3W
snap together to protect the cable.
The extender housing is not watertight, but the inner flange
rings on the chase nipple and the HB300W housing fit into
grooved rubber rings on the the cable. This keeps moisture
from entering the fixture and sensor at those locations.
