Recommended Setup
Figure 3.
OCS 100C Front Panel Features and Controls
With the OCS in the default or recommended settings (A2 OFF), the OCS requires both the IR sensor AND the US sensor to
detect occupancy to turn ON. Only one sensor (PIR or US) needs to trigger to reset the timer for the OCS to remain ON while the
room is still occupied. When the OCS is in the OFF state, no occupancy is detected.
Follow these steps to setup the OCS to detect occupancy with minimal false detection:
NOTE:
We recommend using the OCS 100C in the default settings when beginning the setup or the test mode. If needed,
make slight adjustments at a time from the default sensitivity settings.
Keep all the DIP switches and rotary dials in the default positions.
1.
Set the OCS in Test Mode.
2.
Enter the room several times to verify if the IR detector is detecting movement (red LEDs flash).
3.
If the red LEDs flash when entering the room, the default red infrared sensitivity dial is set correctly.
•
Verify the red LEDs flash with movement throughout the room.
•
If the red LEDs do not flash, turn the red infrared sensitivity dial to decrease or increase IR sensitivity, until the red LEDs
•
always flash when entering the room or making movements throughout the room.
To avoid false detections when the room is unoccupied, do not adjust the sensor too sensitively.
•
Enter the room and verify if the US detector is detecting movement (green LEDs flash).
4.
If the green LEDs flash when entering the room, the default green ultrasonic range dial is set correctly. This sensor is very
•
sensitive.
Verify the green LEDs flash with movement throughout the room.
•
If the green LEDs do not flash, turn the green ultrasonic range dial to decrease or increase US sensitivity, until the green
•
LEDs always flash when entering the room or making movements throughout the room.
To avoid false detections when the room is unoccupied, do not adjust the sensor too sensitively.
•
Leave the room and close the door. Wait until the Digital output state, relay or red and green LEDs stay OFF. Wait several
5.
minutes to ensure there are no false detections.
If the door remains open, the US sensor may detect changes.
•
If possible, wait longer, to confirm no IR or US change is registered.
•
Enter the room again, to confirm the Digital input state relay, red and green LEDs turn ON.

NOTE:
After going through these steps and verifying the OCS is setup to accommodate the room, do not adjust the DIP
switches or dials.
Automatic Mode
Out of the box, the OCS 100C can be setup in Automatic Mode, where no manual sensitivity adjustments are needed and
sensitivity learning and adjustments are made automatically. For simple setup, we recommend keeping the OCS in the default
settings and flipping the B4 Dip switch to the OFF (Auto) position. The OCS is ready to mount (see
