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.

The settings for DIP Switches B3 (timer adjust) and B4 (sensitivity adjust can be set to Automatic mode or Manual mode.
•
Automatic mode — The sensors automatically adjust for changes in usage and seasons, eliminating the need for
•
manual adjustments and improving system performance.
Manual mode — The user sets the parameters of the sensors using the DIP Switches B1 and B2 set together, and
•
the dials.

The US sensor emits ultrasonic sound waves into an area and measures the speed of their return to detect the presence of people. - Page 2 Occupancy Sensor OCS 100W • Setup Guide (Continued) Timer Setting (B1 and B2) (see figure 2 on the previous page) — The occupancy sensor has a built in timer feature. • When the sensor detects motion, it instantly triggers ON (high). Once occupancy is no longer detected, the timer begins.

Page 3: Sensor Coverage
Sensor Placement and Installation Options When placing the sensor in a room, be sure the sensor is not aimed out through a door. The sensor can detect hallway traffic, causing false triggers. PIR sensors trigger in response to changes in the amount of IR arriving from any of their segments of view within a direct line of sight from the sensor. -
