To warn an occupant that the load is about to be turned off, the OSR300S
provides audible alerts.

Records typical occupancy patterns. Using this history
(which is constantly updated), it chooses an optimal
time delay from two minutes (if the space is usually
vacant) up to 30 minutes (if the space gets heavy
usage). SmartSet behavior starts immediately, and is
refined continually as history is collected.
DIP switch selections provide fixed time delays of
5, 10, 15, 20 or 30 minutes.
Use for rooms that have frequent walk-through traffic
(i.e., room that accepts mail deliveries). The OSR300S
turns the load 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 SmartSet or Fixed time delay applies.
To confirm proper operation of the sensor, a short
initial time delay of 15 seconds is set as the default
(SmartSet/Test) mode. This Test Mode cancels
automatically after five minutes, or if a fixed time
delay is selected. To reenable the Test Mode for an
additional five minutes, change the time delay from
any fixed amount to the SmartSet/Test setting.
Both relays use the same Time Delay, unless DIP
switch #4 is turned on, enabling a delayed disconnect
for relay 2. When the delayed disconnect is enabled,
relay 2 turns off 10 minutes after relay 1 and during
Test Mode, relay 2 turns off 10 seconds after relay 1.
The OSR300S monitors the controlled environment
and automatically selects the maximum sensitivity
setting that will provide reliable operation without
false detection. This setting is constantly updated.
Fixed sensitivity mode, reduces detection range.
Sensor "chirps" twice – at one minute and at
30 seconds before turn-off. A distinct alert sounds
10 seconds before the lights go off.
No warning is provided.
