OSFHU
BASIC OPERATION
Passive Infrared Technology (PIR) is used to sense
occupancy by comparing the infrared energy
from an object in motion and the background
space. PIR sensors minimize false ON from back-
ground environmental conditions such as air
movement to provide reliable detection of line-
of-sight motion.
The OSFHU high-bay occupancy sensor is spe-
cifically designed for high mounted areas such
as warehouses, manufacturing and other high
ceiling applications. The OSFHU installs directly
to an industrial fluorescent luminaire or an elec-
trical junction box. It is a self-contained sensor
and relay that turns individual light fixtures ON or
OFF based on occupancy in the detection zone.
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.
To improve the field-of-view for deep body
fixtures, a separate offset adapter accessory
(OSFLO or OSFOA) can be used to position the
sensor below the fixture body. The adapter sim-
ply 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.
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. For deep body fixtures, the
OSFLO or OSFOA accessory installs into the fix-
ture 1/2” knockout using the provided lock-nut.
The OSFHU sensor is installed in one of three,
1/2” punch-outs positioning the OSFHU at the
correct field-of-view position flush or below the
fixture reflector assembly. When applicable, wir-
ing is routed through the OSFLO or OSFOA to the
fixture body for wiring.
