BASIC OPERATION
The High Bay Occupancy Sensor is designed
simply to automatically turn lights ON or OFF.
The sensor utilizes Passive Infrared Technology
(PIR) combined with Fresnel Lenses to determine
when an area is occupied. This is determined
when a heat source is detected and moves from
one facet in the lens to another. The sensor rec-
ognizes this as motion and provides power to the
light fixture. Simultaneously a timer is started
and restarts with each motion, once expired, the
lights will turn OFF.
The high bay sensor maximizes energy sav-
ings, incorporating false detection algorithms to
eliminate false ON’s by nuisance tripping or back-
ground environmental conditions. The sensor
also optimizes energy savings and safety con-
cerns during power loss scenerios by assuming a
return to last known state of operation.
APPLICATIONS
The OSFHU High Bay Occupancy Sensor is spe-
cifically designed and assembled to reduce
the amount of labor required during the fixture
assembly process and at time of installation.
These sensors are for use in spaces where cel-
ing heights can vary from 8 to 40 feet, such as
warehouses, manufacturing facilities, produc-
tion, industrial area, and all other high ceiling
applications.
It comes with three interchangeable lenses for
use in either a 360° high-bay or 360° low-bay
general area or an aisle way. The OSFHU provides
reliable coverage up to 40 ft. mounting heights.
The OSFHU is also available in a model for cold
storage applications with temperatures as low
as -40° F.
INSTALLATION
The OSFHU mounts directly to an industrial flu-
orescent fixture or an electrical junction box
through a standard 1/2” knockout using the
provided lock-nut. Wiring is connected inside
the fixture body. To improve the field-of-view
for deep body fixtures, a separate offset adap-
tor accessory (OSFLO or OSFOA) can be used to
position the sensor below the fixture body. The
adapter simply snaps into a 1/2” knockout on the
end of the industrial fixture to attach the sensor.
The OSFHU and OSFLO/OSFOA provides the most
labor savings available with quick snap, 42” wire
leads, and no power required to configure.
