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.

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.

ADJUSTMENTS
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):
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.

OFF Controlled by Occupancy
ON PIR override. Load always ON

MOUNTING OPTIONS
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.

LENS COVERAGE
Coverage patterns, density and range, are determined by the type of Lens attached to the HB300W.
Currently, there are three lenses available for the HB300W series sensors: HBL2W, HBL3W, and HBL7W.
• The HBL1W lens is best suited for high ceiling aisleway applications and a 60’ linear detection range at a mounting hieight of 40’.
• The HBL2W,HBL3W, and HBL7W lenses are best for open area coverage. They have multi-cell, multi-tier Fresnel lenses with a
360° view.
▸ The HBL2W covers a 48’ diameter area at a height of 8’.
▸ The HBL3W covers a 40’ diameter area at a height of 20’.
▸ The HBL7W lens is designed for higher mounting between 20’ and 40’. It covers a 100’ diameter area at a height of 40’.
For a complete description of each lens coverage pattern, see the HBLx Lens Coverage Guide.
TESTING
1. When mounting and wiring are complete, cover up the sensor to prevent it from detecting motion.
2. Apply power to the sensor and light fixture. Lights may turn ON during the 60-second start-up period.
3. Wait for the start-up period to end. For the next 1 to 2 minutes the sensor runs through a self-diagnostic routine.
4. If the load came on during the start-up period, wait for it to turn OFF, indicating the self diagnostic routine is complete.
5. Uncover the sensor and confirm that when the sensor detects motion, it’s red LED blinks and the light turns ON.
6. Disconnect power.
7. Attach the lens as shown in the assembly drawing. Tighten securely to ensure that seal is complete.
IMPORTANT START-UP INFORMATION
A 60-second start-up period occurs during initial installation and after a power failure of 5 minutes or more. After applying power to the
sensor wait at least 60 seconds for the sensor to begin detecting occupancy and the load to turn ON. It may turn ON during the start-up
period, depending on the state of the relay when power was off.
• If the sensor detects occupancy during the start-up, when the load turns ON it stays ON as long as the sensor continues to detect
motion, plus the Time Delay.
• If no occupancy is detected during the 60-second start-up, the load may come on anyway during the start-up. If no occupancy is
detected by the time the start-up is complete, the relay opens and the load turns OFF.
TROUBLESHOOTING
To confirm proper operation, review the Start-Up and Testing information.
Red LED on sensor module does not blink:
Check for proper sensor wire connections and make sure they are tightly secured.
Red LED blinks but lights do not turn ON:
1. Make sure that power to the sensor has been ON continuously for at least one minute, then
a. Turn OFF power to the sensor. The relay will close.
b. Turn ON power to the sensor. The load should come ON. If not, continue with step 2.
2. Check power connections to the load.
3. Check all sensor wire connections. Verify the load wire is tightly secured.
Lights will not turn OFF:
1. If there is no motion from people or equipment in the sensor’s view but the red LED blinks, look for any nearby source of infrared
energy (heat) in motion, such as turbulent air from a heating or cooling supply, or other sources such as heat from the fluorescent
lamps in the fixture.
• Mount the sensor so that it’s lens is below the edge of the fixture and does not directly view the lamps.
• Divert the air supply away from the sensor, or move the sensor.
2. Verify time delay set in switches 3-7. The time delay can be set from 15 seconds to 30 minutes. Ensure that the time delay is set to
the desired delay and that there is no movement within the sensor’s view for that time period.
3. Check Override DIP switch setting. If switch 8 is ON, the PIR is overridden. Occupancy control functions are overridden and the
load stays ON.
4. Check sensor wire connections. Verify that all connections are complete.
