The OCS 100C is a dual technology occupancy sensor that can be used to automate meeting and presentation spaces when
used with Extron control products. The OCS is equipped with ultrasonic (US), infrared (PIR), and photocell sensors that can be
used together to report ambient light conditions and room occupancy. Sensors can be wired directly to Extron controller products
equipped with Digital I/Os ports or via eBUS, when using optional eBUS interface accessories.

The OCS requires 24 VDC for operation. If local 24 V power is not available, use the included 12 V to 24 V power converter.

NOTE: The OCS 100C is designed to detect occupancy using both the PIR and US sensors with their default settings to

avoid false detections.

• Ultrasonic sensors (4) — Detect movement in the room, based on ultrasonic sound waves. The US sensor emits ultrasonic

sound waves into an area and measures the speed of their return to detect the presence of people. Frequency changes are
caused by the movement of people, which is detected by the US waves.

• Ultrasonic (US) Green LED status indicators (2) — Flash when the ultrasonic sensors detect occupancy.

• Fresnel lens — Diffracts the incoming light and directs the light to the infrared sensor.

• Retainer Ring — Holds the optional IR mask in place. Remove to access all controls and DIP switches. Insert the at end of

a small screwdriver into the notch in the retainer ring to lever it up and off.

• Infrared (PIR) Red LED status indicator — Located behind the fresnel lens, these LEDs ash when the infrared sensor

detects occupancy.

• Infrared Sensor — The infrared (PIR) sensor detects the presence of people based on the difference between the heat

generated by moving people versus the ambient room temperature.

If A2 is set to OFF, both the PIR and US sensors must
be triggered (simultaneously) before the OCS reports an
occupancy signal. If A2 is set to ON, the OCS reports
occupancy based on only one of the sensors being
triggered. When only one sensor is desired, set A2 to ON
and adjust the dials accordingly. If A2 is ON, false detection
when the room is not occupied increases.

indicators are a distraction or you want to disable the
ashing LEDs, A3 should be set to ON.

Only applicable when Timer (B3) or Sensitivity adjust (B4) or
both are set to Automatic mode (OFF). Toggling A4 ON then
OFF will reset any stored learned adjustments.

• Full counter clock wise (CCW) = 8 minutes

• Full clock wise (CW) = 42 minutes

• Timer operation —

• When the sensor detects motion, it instantly triggers ON.

• Once occupancy is no longer detected, the timer begins. If no motion is detected and the timer expires, then the

sensor triggers OFF.

• Setting to Manual mode allows for more predicted behavior

and is better suited for automating AV applications.

• Setting to Automatic mode allows the sensor to learn over

time the ideal timer and sensitivity adjustments for the space
and usage trends. This is better suited for automating lighting
applications.

• All adjustment dials are disabled when set to Automatic (OFF).

NOTE: If it takes too long for the OCS to turn off when the room is unoccupied, adjust the timer to 8 minutes and

extend the timer via the configuration of the connected control processor. This setup reduces false detection.

• Test mode (8 second timer):

• Red Infrared Sensitivity Dial — Adjust this dial to increase or decrease infrared sensitivity.

• Green Ultrasonic Sensitivity Dial — Adjust this dial to increase or decrease ultrasonic sensitivity.

• Blue Photocell Sensitivity Dial — The photocell prevents the sensor from triggering on when the area is adequately lit with

1. Open the retainer ring.

2. Rotate the black timer dial to about midway (50% or 12 o’clock).

3. Return to minimum setting (full CCW).

4. The timer will remain in the 8 second test mode for 1 hour, then automatically reset to 8 minutes.

5. To manually force the timer out of the 8 second test mode, turn the timer adjustment approximately 1/16 inch

clockwise. The setting is slightly above minimum (just above the 8 minute setting).

• Turn clockwise (CW) to increase sensitivity. Minor movements are detected as occupancy.

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, causing it to activate with less light.

• Turn clockwise to increase photocell sensitivity, requiring brighter light to activate the sensor.

• Factory default is 100% (full clockwise) — Photocell sensor is disabled.

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.

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 LEDs ash).

• If the red LEDs ash when entering the room, the default red infrared sensitivity dial is set correctly.

• Verify the red LEDs ash with movement throughout the room.

• If the red LEDs do not ash, turn the red infrared sensitivity dial to decrease or increase IR sensitivity, until the red LEDs

always ash 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 LEDs ash).

• If the green LEDs ash when entering the room, the default green ultrasonic range dial is set correctly. This sensor is very

sensitive.

• Verify the green LEDs ash with movement throughout the room.

• If the green LEDs do not ash, turn the green ultrasonic range dial to decrease or increase US sensitivity, until the green

LEDs always ash 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 conrm no IR or US change is registered.

6. Enter the room again, to conrm 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 ipping the B4 Dip switch to the OFF (Auto) position. The OCS is ready to mount (see Installation on page5).

Troubleshooting

Problem Possible Cause Test Solution

Sensor remains ON. Constant noise. Reduce both green and red

knobs by 1/8 (15%) turn or
remove noise source.

Sensor remains OFF Sensitivity is set too low. Increase both green and red

knobs by 1/8 (15%) turn.

Sensor remains on too long. Timer setting is too high. Check DIP switch settings. Reduce timer setting.

Hallway trafc turns sensor
on.

Infrared sensor can see into
the hallway.

Put sensor in timer test mode
and walk the hallway.

Move sensor to a less noisy
area within the room.

Move the sensor. If the A2
DIP switch is set to OFF,
set green and red knobs to
normal levels.

Move sensor, so it cannot see
into the hallway or install the
IR blocks.
