DESCRIPTION AND OPERATION
The HB340B-Lx occupancy sensors are designed for automatic lighting control in warehouse high bay applications. All models contain a
passive infrared sensor (PIR). The HB340B-Lx series sensors are modular and are made up of a Power Module and a Lens. The coverage
area is determined by the lens module. There are three different lens available. See the Coverage section for more information.
All models in the HB340B-Lx series use a set of DIP switches to set the time delay and PIR sensitivity, as explained on page 3.
COVERAGE
Coverage patterns, density and range, are determined by the type of Lens attached to the HB340B-Lx.
HB340B-L1 and HB340B-L1M
The L1 Lens offers linear patterns best suited
for high bay aisleway applications. The
Fresnel lens is designed to detect walking
motion when mounted at or around 40’. In
optimal conditions, the lens has a 60’ linear
detection range.
Identical to the HBL1, the HBL1M comes
with opaque adhesive tape applied to the
interior of the lens, cutting off 1/2 of the
coverage pattern. This customized coverage
is ideal for the beginning of aisle ways where
cross traffic could be an issue.
HB340B-L3
The L3 Lens offers 360° coverage and is best suited
for open area and aisleway coverage in high bay
applications. The L3 is a multi-cell, multi-tier Fresnel
lens offering a high density coverage pattern that
spreads over a 24’ diameter area at a height of 20’.

INSTALLATION
WARNING
TURN THE POWER OFF AT THE CIRCUIT
BREAKER BEFORE INSTALLING THE SENSOR.
1. Determine the mounting location appropriate to the features
of the power module and the coverage area. Careful
consideration must be given to sensor placement. Avoid
placing the sensor where the edge of the fixture, shelving or
other obstructions may block the sensor’s line of sight. Mount
the sensor below the edge of the fixture and away from the
fluorescent lamps so that the heat from the lamps does not
affect the sensor.
2. 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 power module, making sure that the flying leads
from the power module are accessible.
4. Connect the line voltage and load wires to the sensor leads as
shown in the Wiring Diagram for the unit’s application.
• Do not allow bare wire to show.
• Make sure all connections are secure.
5. Restore power from the circuit breaker.

The HB340B-Lx can be attached to the fixture or junction box using the back box and chase nipple or directly to the fixture surface via
the two screw holes provided in the Power Module (see Surface mounting below). The Extender Module (HBEM3) allows attaching the
sensor to the side of the fixture in a number of configurations using provided chase nipples.
Back box mounting requires a standard 1/2” knockout for the chase nipple. The Power Module mounts to the back box with a bayonet
type fitting requiring a slight twist of the units to separate them or lock them into place. The box comes ready for side mounting. It can
be modified for rear mounting as follows:
1. Pop out the cap in the rear knockout.
2. Un-snap the chase nipple from the side mount and snap into the rear mounting hole.
3. Use the cap to close the side mount hole.
4. The chase nipple provided can be pushed into a standard 1/2” knockout in a metal fixture [max of 1 mm (0.04”) thick metal] without
the need for the included internal nut. The nut can be used for added security if necessary.
The HBEM3 extender module allows threading the wires through its chase nipples and into the fixture for connection. The two sides of
the HBEM3 are then snapped together to protect the wires. The short chase nipple is designed to snap into the HBNB3 connection box
while the longer chase nipple snaps into any metal fixture or connection box with a standard knockout. The caps on the HBEM3 can be
removed in various configurations to allow moving the chase nipples and adjusting the height of the sensor on the fixture
Surface mounting requires holes in the fixture to pass wires and attach two #6-32 screws through the surface mounting screw holes on
the component side of the Power Module as shown.
