FIXTURE SENSORS & CONTROLS
Description
HB3x0W-Lx occupancy sensors are designed for automatic
lighting control in warehouses and other medium and high bay
wet location applications. They are modular and are made up of
two parts, a Power Module (HB3x0W) and a Lens (HBLxW), sold
separately or in prepackaged combinations.These components
are designed to work as a convenient system. Different models
offer a choice of coverage patterns for a range of applications.
Operation
The HB350W-Lx occupancy sensors are designed to mount to
a light fixture and control one load in that fixture. They can be
wired to control all ballasts in the fixture, or to control half of
the ballasts, providing high/low lighting control. When motion
is detected within the sensor’s coverage area, the relay in the
sensor closes, and lighting loads are automatically turned on.
When motion is no longer detected for the duration of the time
delay setting, the relay opens and the lighting load is turned
off. The sensor’s sensitivity and time delay settings are factory
preset at “normal” and 15 minutes, respectively, which are
suitable for most high bay applications. However, if the values
need to be adjusted for specific applications, they can be easily
changed using the DIP switches on the unit.
Wet Location Rating
Featuring a unique gasketted construction, the sensors carry
the IP65 rating for wet locations. The IP65 rating means the
sensors are protected against dust and low-pressure jets
from all directions. In wet indoor or outdoor environments, the
sensors will operate reliably with this level of protection.
Modular Design
The HB350W-Lx system includes a self-contained, line or low
voltage sensor module with a ½” threaded nipple for attaching
to wet location junction boxes and conduit hubs, and to the
end of a fixture. It also contains a lens module that provides
360° coverage. Different coverage patterns are available by
selecting the different lens options. Sensitivity and time delay
adjustments are set using DIP switches located behind the lens.
Applications
Engineered specifically for wet locations, the HB350W-Lx
is ideal for a range of indoor and outdoor spaces such as
nurseries and greenhouses, food processing facilities, parking
garages, and industrial facilities. An optional HB Extender
Module provides additional mounting flexibility.
