Extron electronics OCS 100C Setup Manual

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 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.

OCS 100C Front Panel Features
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 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.

OCS 100C Controls
Switch is not used.
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 notification whenever
the PIR or US sensors are triggered. When the visual LED
indicators are a distraction or you want to disable the
flashing 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.
