Leviton's Cat. No. ODS0D- ID 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- ID provides automatic switching of two separate
lighting loads from a single unit. It is compatible with incandes-
cent, fluorescent and low-voltage lighting. The unit features dual
manual-override switches that can be used to toggle the
O N / O FF status of each lighting load while an area is occupied.
The ODS0D- ID 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.
B A SIC OPERAT ION
The ODS0D- ID uses passive infrared (PIR) detection technology
to monitor a room for occupancy through a segmented Fr e s n e l
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-O FF time adjustment prevents the lights from switch-
ing 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-O FF time interval. A s e l f - a d j u s t i n g
d e l a y e d -OFF time feature compensates for real-time occu-
pancy 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-O FF 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
O D S 0 D- ID will switch 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 follow-
ing 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.
N OTE: The Self-Adjusting De l a y e d -O FF Time and the Wa l k -Through
features are factory-preset features in the ODS0D - ID. These features
can be disabled if required—See "Non-Adaptive Mode."
