OSF20 Fixture Mount PIR Outdoor Integral Luminaire Occupancy Sensor
User Manual
Description
The Fixture Mount PIR Outdoor Integral Luminaire Occupancy Sensor (OSF20) is designed to be mounted directly into a luminaire and is ideal for indoor or outdoor locations. The OSF20 offers a sensor and relay in one device. The wiring and housing of the sensor is installed adjacent to the ballast and hidden from view behind the reflector cover. Only the PIR detector dome lens and locking ring are visible on the exterior of the fixture. The sensor comes with two interchangeable lenses for use in a 360° high bay general area and low bay applications. It also includes an aisle mask accessory.
Applications
Leviton’s Fixture Mount Outdoor Integral Luminaire Occupancy Sensor is designed specifically for pre-wiring and installing inside of luminaire fixtures including:
- Supermarket meat departments
- Food processing plants
- Parking garages
Operation
The OSF20 utilizes passive infrared (PIR) technology with autoON/auto-OFF
operation and an adjustable time delay to detect motion within its field of
view. A small semiconductor heat detector resides behind a multi-zone optical
lens, making the sensor sensitive to the heat emitted by occupants. This
Fresnel lens establishes dozens of zones of detection. In order to initially
trigger the sensor, the source of heat must move from one zone of detection to
another. The OSF20 is most effective in sensing motion across its field-of-
view.
Once the device senses motion, the sensor will automatically turn the lights
ON. When motion is no longer detected, the sensor will conclude that the space
is unoccupied. This will initiate the delay timer. If the delay timer expires
and no motion is detected, the lights will turn OFF. If motion is detected,
the delay timer will stop and the lights will remain ON.
Features
- Easy installation with 7.5” leads allows for easy connection to any ballast
- Aisle mask accessory included
- Low voltage 24V model available—requires a separate power supply
- Passive infrared detection technology for accurate sensing
- True Zero-Cross relay technology provides maximum contact life and compatibility with electronic ballasts
- Adjustable time delay located on sensor housing for easy access
- Aesthetically pleasing design
- Compact size for tight spaces
- 20-40’ standard mounting heights for indoor and outdoor use
- Internal fixture mount reduces number of devices on ceiling
- Passive Infrared Technology (PIR): the OSF20 uses PIR technology to detect motion
- Aisle mask: one unit includes interchangeable 360° high-bay (20-40’) and 360° low-bay (8-25’) lenses and an aisle mask accessory
- Time delay: the time out occurs when motion is no longer detected by the sensor and the device counts a set amount of time before turning off the load. If the device sensor detects motion during this ’time delay’, the count resets and the device initiates a new count. The time delay can be adjusted to 30 seconds, 10, 20 and 30 minutes, respectively.
- Zero-crossing circuitry: relay uses a zero-crossing circuitry to provide reliable, long-life operation
- LED: a green LED blinks when motion is detected
Installation
The OSF20 is designed to mount directly into a light fixture, with only the PIR lens being visible. The wiring and housing of the sensor is installed adjacent to the ballast, hidden from view behind the reflector’s cover.
