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.

(either PIR or

US detection)

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 notication 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.
