Occupancy Sensor OCS 100W • Setup Guide
The OCS 100W 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, USB 5 V to 24 V power
converter.
NOTE: The OCS 100W is designed to detect occupancy using both the PIR and US sensors with their default settings to
avoid false detections.

• Ultrasonic Sensors (2) — 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 indicator — Flashes when the ultrasonic sensors detect occupancy.
• Infrared/Photocell Sensor and Fresnel Lens —
• The Fresnel lens diffracts the incoming light and directs the light to the infrared sensor behind it.
• 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.
• Infrared (PIR) Red LED status indicator — Flashes when the infrared sensor detects occupancy.
• Removable Front Cover — Conceals all controls and DIP switches.
• DIP Switches (A) —

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.

Setting A3 to OFF provides a visual notication whenever
the PIR or US sensors are triggered. When the visual LED
indicators are a distraction or you want to disable the
ashing LEDs, A3 should be set to ON.

(green) adjustment dials.
• 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).
4 Sensitivity adjust Automatic *Manual
*Default and recommended
NOTE: B3 must be set to ON for Manual mode, in order to adjust the timer switches manually. B4 must be set to ON for
Manual mode, in order to adjust the infrared sensitivity and US sensitivity dials manually.
• Timer Setting (B1 and B2) — The occupancy sensor has a built-in timer feature. In Manual mode (B3 set to ON), 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.
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.
NOTE: If it takes too long for the OCS to turn off when the room is unoccupied, adjust the timer to 8 or 4 minutes
and extend the timer via the configuration of the connected control processor. This setup reduces false detection.
• Blue Timer Test Button —
• To enable an 8 second timer test mode, push the blue button once. The test mode lasts 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 ashes, returning the OCS to the
settings dened by the dip switches.
• Red Infrared Sensitivity Dial — Adjust this dial to increase or decrease infrared sensitivity.
• Turn counter-clockwise (CCW) to decrease sensitivity. Major movements are needed to detect occupancy.
• Turn clockwise (CW) to increase sensitivity. Minor movements are detected as occupancy.
• The factory default setting is at 75%.
• Green Ultrasonic Sensitivity Dial — Adjust this dial to increase or decrease ultrasonic sensitivity.
• Turn counterclockwise (CCW) to decrease sensitivity. Major movements are needed to detect occupancy.
• Turn clockwise (CW) to increase sensitivity. Minor movements are detected as occupancy.
• The factory default setting is at 100%.
• Blue Photocell Sensitivity Dial — Photocell prevents the sensor from triggering on when the area is adequately lit with
natural light and 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 counterclockwise 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.
• Range — 10 to 1000 lux

Figure 3. 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 set up 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 ashes).
• If the red LED ashes when entering the room, the default red infrared sensitivity dial is set correctly.
• Verify the red LED ashes with movement throughout the room.
• Turn the red infrared sensitivity dial to decrease or increase IR sensitivity, until the red LED only ashes when entering the
room or making movements throughout the room.
• To avoid false detections when the room is unoccupied, do not make the sensor too sensitive.
4. Enter the room and verify if the US detector is detecting movement (green LED ashes).
• If the green LED ashes when entering the room, the default green ultrasonic range dial is set correctly. This sensor is
very sensitive.
• Verify the green LED ashes with movement throughout the room.
• Turn the green ultrasonic range dial to decrease or increase US sensitivity, until the green LED only ashes when entering
the room or making movements throughout the room.
• To avoid false detections when the room is unoccupied, do not make the sensor too sensitive.
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 conrm no IR or US change is registered.
6. Enter the room again to conrm the Digital output state, relay, red, or green LEDs turn ON.
NOTE: After going through these steps and verifying the OCS is set up to accommodate the room, do not adjust the DIP
switches or dials.
Automatic Mode
Out of the box, the OCS 100W can be set up 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 page5).
