FOR USE IN MANY APPLICATIONS INDOOR AND OUTDOOR
OSFHU-CTW Fixture Mount Occupancy Sensors
The OSFHU self-contained sensor mounts directly to a luminaire or electrical box to provide local occupancy control for either general area or aisle way pattern detection using PIR technology with a microprocessor based digital architecture that minimizes false triggering. The OSFHU provides a trouble-free "install and forget" solution for high-bay lighting control.
Passive Infrared Technology (PIR)
Interchangeable lenses for 360 high-bay, 360 low-bay, and
Use in warehouses, manufacturing, and other high ceilings
Cold storage application model available
Mounts directly to industrial style fluorescent luminaires
8 ft. 40 ft. mounting heights
The OSFHU 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 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 (OSFOA-00W) 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.
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 background environmental conditions such as air movement to provide reliable detection of line-of-sight motion.
The OSFHU installs directly to an industrial fluorescent fixture or an electrical junction box through a standard 1/2" knockout using provided lock-nut. Wiring is connected inside the fixture body. For deep body fixtures, the accessory OSFOA is a two piece plastic offset that installs into the fixture 1/2" knockout using the provided lock-nut. Then 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. Wiring is routed through the OSFOA to the fixture body for wiring.
The OSFHU sensor is a self-contained, line voltage sensor that easily installs on individual fixtures using
standard 1/2" knockouts. Simply make the electrical connections inside the ballast
compartment, install the appropriate, adjustable lens assembly included and the sensor is ready. For deep body fixtures, the OSFOA positions the OSFHU sensor flush or below the bottom of the reflector giving the sensor full field-of-view.
Relay uses a zero crossing circuitry to provide reliable, long-life operation.
The 360 high-bay PIR lens provides a 2:1 spacing to mounting height coverage under 25 ft. mounting and a 1.5:1 for heights up to 40 ft. mounting. The 360 low-bay lens provides 2:1 spacing to mounting height coverage for 8 ft. to 20 ft. mounting. The aisle lens is designed to provide detection of 60 ft. long by 20 ft. wide for heights up to 40 ft. mounting.
