Legrand OS300S 120/277VAC - Manual (Page 3)

Walk-Through Use for rooms that have frequent walk-through traffic
Mode (ie. room that accepts mail deliveries). The OS300S
turns the lights OFF three minutes after the area is
initially occupied, if no motion is detected after the
first 30 seconds. If motion continues beyond the first
30 seconds, the set time delay applies.
Test Mode To test the sensor, a short time delay of 5 seconds is
set as the default (SmartSet/Test). Test Mode cancels
automatically after five minutes, or if a fixed time
delay is selected. To restart the Test Mode, change the
time delay switch setting to any fixed amount and then
return it to the SmartSet/Test setting.
Alerts
The OS300S can provide alerts as a warning before the lights turn OFF.

Sensitivity Adjustment
The OS300S constantly monitors the controlled environment and automatically
adjusts to avoid common ambient conditions that can cause false detections,
while providing maximum coverage.
Light Level Control Lights are held OFF, even when the controlled area is
Enabled occupied, as long as the ambient light level is greater
than a chosen threshold level. The light level can be
set with the overhead lights ON or OFF.
High Default setting. Suitable for most applications.
Low Reduces sensitivity by approximately 50%. Useful in
cases where the sensor is detecting movement outside
of the desired area (also consider masking the lens)
and where heat sources cause unnecessary activation.
Light Flash Alert Lights will flash OFF for one second, one minute
before they will be turned OFF by the sensor.
Audible Alerts Sensor will “chirp” twice, at one minute and at
30 seconds before turn-OFF. A distinct alert will sound
10 seconds before the lights go OFF.
Dual Alerts When both Light Flash Alerts and Audible Alerts are
selected, the Audible Alert at one minute remaining
is replaced by the Light Flash Alert.
No Alerts No warning will be provided.
