OCS 100W 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 100W in the default settings when beginning the setup or the test mode. If needed,
adjust slightly from the default sensitivity settings.
1.
Keep all the DIP switches and rotary dials in the default positions.
2.
Set the OCS in Test Mode.
3.
Enter the room several times to verify if the
IR detector
is detecting movement (red LED flashes).
•
If the red LED flashes when entering the room, the default red infrared sensitivity dial is set correctly.
•
Verify the red LED flashes with movement throughout the room.
•
If the red LED
does not
flash, turn the red infrared sensitivity dial to decrease or increase IR sensitivity, until the red LED
always flashes 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.
4.
Enter the room and verify if the
US detector
is detecting movement (green LED flashes).
•
If the green LED flashes when entering the room, the default green ultrasonic range dial is set correctly. This sensor is
very sensitive.
•
Verify the green LED flashes with movement throughout the room.
•
If the green LED
does not
flash, turn the green ultrasonic range dial to decrease or increase US sensitivity, until the green
LED always flashes 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.
5.
Leave the room and close the door. Wait until the Digital output state, relay or red and green LEDs stay OFF. Wait several
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.
6.
Enter the room again, to confirm the Digital output state, relay, red, or 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 100W 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
