Occupancy Sensor OCS 100C

Occupancy Sensor OCS 100C · Setup Guide
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, USB 5 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.

· Infrared/Photocell (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 flat 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 flash 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.

Note
If enabled (set to ON) the sensor will not detect minor changes and movement. This could result in missed detection, with a low trigger-on threshold.
Applies to the Timer (black), Infrared sensitivity (red), and Ultrasonic sensitivity (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).

*Default and recommended settings

NOTE: B3 and B4 must be set to ON for Manual mode, in order to adjust the timer, infrared sensitivity, and US sensitivity dials manually.

· Black Timer Dial — The occupancy sensor has a built-in timer feature. Use the black timer dial to set the amount of time before the sensor triggers OFF. The factory default setting is 8 minutes.
· Timer range — 8 minutes to 42 minutes. · 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.
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): 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).
· Red Infrared Sensitivity Dial — Adjust this dial to increase or decrease infrared sensitivity. · Turn clockwise (CW) to increase sensitivity. Minor movements are detected as occupancy. · Turn counterclockwise (CCW) to decrease sensitivity. Major movements are needed to detect occupancy. · The factory default setting is at 75%.
· Green Ultrasonic Sensitivity Dial — Adjust this dial to increase or decrease ultrasonic sensitivity. · Turn clockwise (CW) to increase sensitivity. Minor movement are detected as occupancy. · Turn counterclockwise (CCW) to decrease sensitivity. Major movements are needed to detect occupancy. · The factory default setting is at 50%.
· Blue Photocell Sensitivity Dial — The photocell prevents the sensor from triggering on when the area is adequately lit with natural light and 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 2

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 set up 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 flash).
· 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. · Turn the red infrared sensitivity dial to decrease or increase IR sensitivity, until the red LEDs only flash 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 LEDs flash). · 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. · Turn the green ultrasonic range dial to decrease or increase US sensitivity, until the green LEDs only flash 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 confirm no IR or US change is registered. 6. 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 set up to accommodate the room, do not adjust the DIP switches or dials.
Automatic Mode
Out of the box, the OCS 100C 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 flipping the B4 Dip switch to the OFF (Auto) position. The OCS is ready to mount (see Installation on page 5).

Typically used for lighting applications. When wiring the gray wires of the OCS to Extron products with Digital or FLEX Input ports, configure the ports as Input without pull up. The output state will remain OFF 0 VDC when occupancy is detected but there is high amount of ambient or natural light in the room. Only when there is low or no ambient or natural light in the room and occupancy is detected will the output state trigger ON 21 VDC. Use the shared black ground wire.

Troubleshooting
Problem Sensor remains ON.
Sensor remains OFF
Sensor remains on too long. Hallway traffic turns sensor on.

Possible Cause Constant noise.
Sensitivity is set too low.
Timer setting is too high. Infrared sensor can see into the hallway.

Test Reduce both green and red knobs by 1/8 (15%) turn or remove noise source. Increase both green and red knobs by 1/8 (15%) turn.
Check DIP switch settings. Put sensor in timer test mode and walk the hallway.

Solution
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. Reduce timer setting. Move sensor, so it cannot see into the hallway or install the IR masks.
