High-Bay Occupancy Sensor

OSFHU
BASIC OPERATION
The OSFHU Passive Infrared (PIR) Fixture Mount
High-Bay Occupancy Sensor is specifically
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
electrical 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 two
interchangeable lenses for use in either a
360° high-bay or 360° low-bay general area
or a mask for 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 (-40°C).
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
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, 21” wire
leads, and no power required to configure.
Passive Infrared Technology is used to sense
occupancy by comparing the infrared energy
from an object in motion and the background
space. PIR sensors minimize false ONs from
background environmental conditions such as
air movement to provide reliable detection of
line-of-sight motion.
INSTALLATION
The OSFHU mounts directly to an industrial
fluorescent fixture or an electrical junction box
through a standard 1/2” knockout using the
two provided lock-nuts. Wiring is connected
inside the fixture body. For deep body fixtures,
the OSFLO or OSFOA accessory installs into the
fixture 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,
wiring is routed through the OSFLO or OSFOA to
the fixture body for wiring.

FEATURES
• Quicksnap: built into the 1/2” nipple, this
locking mechanism allows for the fastest and
easiest mounting not requiring a threaded lock-
nut
• Reduce time and materials: easily reach the
ballast at either end of the fixture without
requiring more wire or connectors with the
included 21” wire leads
• Fast, easy time delay setting: can be set at
any time without requiring power to the sensor;
time delay is variable from 30s-20m
• Instantly verify fixture operation and
wiring connections: “instant ON” closing relay
fires lamps in under 5 seconds
• High Inrush Stability (H.I.S. Technology):
- Zero crossing circuitry optimizes relay
operation for reliable, long-life operation
- Robust mechanical latching relay is durable for
all load types
• Auto temperature calibration: automatically
adjusts the PIR sensitivity as ambient
temperature rises to increase detection of heat
movement through the field-of-view
• Return to last state: for safety and energy
savings, the OSFHU contains a latching relay so
that in the event power is lost to the device, the
device will return to the last known state of the
relay
• False detection intelligence: for increased
energy savings and to mitigate nuisance
tripping, the super bright LED indicates
advanced detection has been activated and the
lights will only turn ON when true occupancy has
been determined
