Legrand OS300S 120/277VAC - Manual (Page 2)

SmartSet™ Time Records typical occupancy patterns. Using this history
Delays (which is constantly updated), it chooses an optimal
time delay from 7 minutes (when space is usually
vacant) up to 30 minutes (for times that show heavy
usage). SmartSet behavior starts immediately, and
is refined continually as history is collected.
Fixed Time Delay DIP switch selections provide fixed time delays of 5,
10, 15, 20, 25 or 30 minutes.
Auto On Mode The OS300S will turn lights ON and OFF automatically
based on occupancy. If the lights are turned OFF
manually, automatic-ON operation will not be
reenabled until no motion is detected for five minutes.
This feature prevents lights from accidentally being
turned ON after they were deliberately turned OFF.
Manual On Mode Occupants must turn ON the lights by pressing the
Auto-ON/OFF button. The sensor will then keep the
lights ON until no motion is detected for the selected
time delay period. There is a 30 second reset delay.
If motion is detected during this time, the sensor will
turn the lights back ON automatically. After the reset
delay time has elapsed, the Auto-ON/OFF button must
be pressed to turn the lights ON.
Button Override The lights can be turned ON or OFF by pressing the
Auto ON/OFF button, regardless of the operating
mode.

UNIT DESCRIPTION AND OPERATION
The OS300S is a passive infrared wall switch that turns lighting ON and OFF
based on occupancy and ambient light levels. SmartSet™ technology allows
the sensor to be installed without any adjustments. This technology allows the
sensor to automatically adjust to the usage patterns in the space. Alternate
operating modes, selected by DIP switch settings, can be combined to create the
ideal custom control.
Time Delays
The OS300S time delay holds the lights ON until no motion is detected for a time
period of 5 seconds to 30 minutes, at which point it turns the lights OFF. The
sensor can automatically select the time delay, or the user can choose a fixed
delay.
