Extron electronics OCS 100W Setup Manual

Occupancy Sensor OCS 100W • Setup Guide
The OCS 100W is a wall-mounted occupancy sensor that incorporates ultrasonic (US) and passive infrared (PIR) into a dual-
technology sensor. 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. The PIR
sensor detects the presence of people based on the difference between the heat generated by moving people versus the ambient
room temperature.
The OCS 100W has a 24 VDC power input, ground/common connection, normally open/closed relay, photocell, and occupancy
output connections.
