• Controls two separate lighting loads from
a single unit
• Manual ON only for the secondary relay
• Features new self-adjusting occupancy sensor
technology with automatic "walk-through" sensing
• 30 Minute maximum time-OUT delay
• CEC Title 24 Compliant
APPLICATION
Leviton's Cat. No. ODS0D-TD Dual-Relay Decora Wall Switch Passive
Infrared (PIR) Occupancy Sensor is used to provide automatic
lighting control for energy savings and convenience in a variety
of commercial applications, including:
• Class rooms • Conference rooms
• Multimedia rooms • Day care centers
The ODS0D-TD provides automatic switching of two separate
lighting loads from a single unit. It is compatible with incandescent,
fluorescent and low-voltage lighting. The unit features dual manual-
override switches that can be used to toggle the ON/OFF status of
each lighting load while an area is occupied. The ODS0D-TD can
be installed in place of two single-pole wall switches and fits in a
standard single-gang wall box. The unit requires a ground
connection for proper operation.
The sensor has an adjustable 30 minute time-delay setting for
the first relay and second relay. To comply with California Energy
Commission's Title 24, the second relay is a manual ON only.
BASIC OPERATION
The ODS0D-TD uses passive infrared (PIR) detection technology
to monitor a room for occupancy through a segmented Fresnel lens.
This specialized lens divides the field of view into sensor zones.
When a person passes into or out of a sensor zone, the sensor
detects motion and switches two separate lighting loads ON. The
lights will remain ON as long as there is an occupant moving through
the sensor zones.
A delayed-OFF time adjustment prevents the lights from switching
OFF when the space is occupied. In order to keep the lights ON,
a person must pass through a sensor zone at least once during the
selected delayed-OFF time interval. A self-adjusting delayed-OFF
time feature compensates for real-time occupancy patterns to
prevent unnecessary ON/OFF switching. An LED indicator blinks each
time the unit detects activity in the sensor zones. When the space
being monitored by the sensor is unoccupied for the length of the
delayed-OFF time interval, the unit will beep 3 times. Ten seconds
after the last warning beep, the unit will switch the lights OFF.

To ensure longer service life and compatibility with electronic
ballasts, the device carefully times the primary relay switching
contact opening and closing with the zero crossing point of the
AC power curve. This minimizes contact wear caused by in-rush
currents from electronic ballasts.
An exclusive walk-through feature addresses the typical situation
where personnel may only enter a room momentarily. The
walk-through feature provides increased energy savings by
preventing the lights from remaining ON for an extended
period after only momentary occupancy.
The walk-through feature operates as follows: The ODS0D-
TD will switch the primary relay lights ON when it detects a
person entering the area it monitors. However, if there is no
occupant activity detected during the 2-1/2 minutes
immediately following the initial entry, the unit recognizes that a
person was just "walking through" the area. It will then
automatically time out. After the initial 2-1/2 minute time
interval expires,
the unit will beep 3 times and then wait 10 seconds before
switching the lights OFF.
NOTE: The Self-Adjusting Delayed-OFF Time and the Walk-Through
features are factory-preset features in the ODS0D-TD. These features
can be disabled if required—See "Non-Adaptive Mode. "
