Specification

PRODUCT DATA
Timer Left In Test Mode - The
sensor remains in an 4 sec.
test mode.
False-On - The sensor
incorrectly turns the lights on.
False-O - The sensor
incorrectly turns the lights o.
An installer accidentally leaves
the sensor in the 4 sec. timer
test mode and the lights may go
o or on every 4 sec.
The sensor detects movement
in the corridor or hallway and
the room lights turn on.
The sensor does not detect
movement because an
occupant sits virtually
motionless at a desk and the
lights turn o.
The sensor automatically resets the timer
to the preset time delay after 15 minutes of
test mode
After an initial movement is sensed,
if another movement is not sensed within
the timer setting then the delayed o time
setting is automatically reduced.
Condition Example Adaptive Reaction
If motion is sensed within a short period after
the lights go o, then the current delayed
o-time setting is increased.
OSC04-RIW OSC15-RIW
Passive Infrared Ceiling
Occupancy Sensor with Isolated Relay
BASIC OPERATION
The OSCxx-RIW Infrared Ceiling Sensor is a low voltage
oc cu pan cy sensor that works in con junc tion with the
Leviton OSPxx Power Pack to control lighting. The sen-
sor’s main function is to turn the lights ON or maintain
the lights ON while movement is detected within the
sensor’s range and to turn the lights OFF when the
space is left un oc cu pied.
The sensor uses a Dual Element PIR heat detector that
resides behind a multi-zone optical lens. This Fresnel
lens es tab lish es dozens of zones of de tec tion. The
sensor is sensitive to the heat emitted by the human
body. In order to trigger the sensor, the source of heat
must move from one zone of sensing to another. Non-
moving hot objects will not cause the lights to turn ON
(like incandescent lights).
Additionally, the sensor is designed with an isolated
relay contact; which enables the sensor to interface
with other systems (example: BAS, HVAC or any dry-
contact capable device or system).
APPLICATIONS
• Classrooms • Workspaces
• Copy rooms • Hallways
• Open areas • Private restrooms
• Small offices
• Conference rooms
FEATURES
• Isolated Relay: Supports HVAC or other Class 2 low
voltage signals
• Supports both 24VAC/VDC power supplies
• Range & Coverage: 450 sq. feet and 1,500 sq. feet
models available.
• Self-Adjusting: Internal microprocessor con tin u al ly
analyzes, evaluates and adjusts the infrared sensi-
tivity and time delay. Performance is kept at a maxi-
mum and user complaints are eliminated.
• Custom white color matched for most common day-
light harvesting architecture
• Uses OSPxx Series Power Pack: Uses Class 2, 24 volt
wiring, three wire connection (low voltage). Multiple
sensors can control single or multiple power packs.
• Additional mid-range lens assembly included for
applications with mounting heights between 12’-20’
• Fast, Simple In stal la tion: Easy ceiling mount, twist-
lock sensor attachment for 360° rotation and flex-
ibility
• Timer Setting Feature: Automatic – 30sec – 30min.
Test mode – 4sec with auto exit programming.
• Non-Volatile Memory: Learned and ad just ed settings
saved in protected memory are not lost during power
outages
• Walk-Through: Provides increased energy savings by
decreasing the time delay to 2.5min when someone
momentarily walks through the monitored space.
• PIR Masking: Pre-scored masking disks are provided
with the device for fine tuning the field-of-view
• High Motion Sensitivity: Large lens area and multi-ele-
ment lens design gives excellent range and sensitivity
• Device: Rugged, high-impact, injection molded plastic.
Color coded leads are 7” long (17.78 cm)
