Occupancy Sensor OCS 100W • Setup Guide (Continued)
Timer Setting (B1 and B2)
•
When the sensor detects motion, it instantly triggers ON (high). Once occupancy is no longer detected, the timer begins.
If no motion is detected and the timer expires, then the sensor triggers OFF (low). In Manual mode, set the B1 and B2
DIP Switches together, as shown in the table above, to set the amount of time before the sensor triggers OFF.
NOTE:
• The B1 and B2 DIP Switches are inactive when the B3 timer adjust DIP Switch is in Automatic Mode.
• The red infrared sensitivity dial and green ultrasonic range dial are inactive when the B4 sensitivity adjust DIP Switch
is set to automatic.
• Blue Timer Test Button
To enable an 8 second timer test mode, push the blue button once. The test mode will last for 1 hour, and then
•
automatically resets to the dip switch settings.
To cancel the 8 second test mode, push and hold the blue button until the red LED flashes, returning the OCS to the
•
settings defined by the dip switches.
• Red Infrared Sensitivity Dial
Turn counter clockwise (CCW) to decrease sensitivity.
•
Turn clockwise (CW) to increase sensitivity.
•
The factory default setting is at 75%.
•
Green Ultrasonic Range Dial
•
Turn counter clockwise (CCW) to decrease sensitivity.
•
Turn clockwise (CW) to increase sensitivity.
•
The factory default setting is at 50%.
•
NOTE:
B4 DIP Switch must be set to ON for Manual mode, in order to adjust the Red Infrared Sensitivity Dial or the Green
Ultrasonic Range Dial manually.
• Blue Photocell Dial
when motion is detected. The sensor must be mounted directly over an area that is representative of the average, natural
room lighting. Before setting the photocell control, wait until the natural light is brightest (optional). Adjust this dial to increase
or decrease photocell sensitivity.
Turn counter clockwise to decrease photocell sensitivity.
•
Turn clockwise to increase photocell sensitivity.
•
Factory default is 100% (full clockwise).
•
Full counter clockwise — Photocell is disabled.
•
Range — 10 to 1000 LUX

— Adjust this dial to increase or decrease infrared sensitivity.
— Adjust this dial to increase or decrease ultrasonic sensitivity.
— Photocell prevents the sensor from triggering on when the area is adequately lit with natural light and
