Extron electronics OCS 100W Setup Manual

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 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.
Front Panel Features and Control

Figure 1. OCS 100W Front Panel Features
• 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) —

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.
