Occupancy Sensor OCS 100C • Setup Guide

The OCS 100C is a ceiling 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 100C has a 24 VDC power input, ground/common connection, normally open/closed relay, photocell, and occupancy

output connections.

Figure 2. OCS 100C Controls

The settings for DIP Switches B3 (timer adjust) and B4

(sensitivity adjust) can be set to:

• 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 following dials.

NOTE:

• The black timer dial is inactive when the B3 timer adjust DIP Switch is in Automatic mode.

• The red infrared sensitivity dial and green ultrasonic range dial are inactive when the B4 sensitivity adjust DIP Switch is

set to Automatic mode.

• Ultrasonic sensors (4) — Detect movement in the room, based

on ultrasonic sound waves.

• Green LED status indicators (2) — Flash when the ultrasonic

sensors detect occupancy.

• Infrared/Photocell lens — Diffracts the incoming light and

directs the light to the infrared/photocell sensor. The infrared/

photocell sensor, controls and DIP switches are located behind

the lens.

• Red LED status indicator — Located behind the

infrared lens, this LED ashes when the infrared sensor

detects occupancy.

• Retainer Ring — Holds the optional IR mask in place. Remove

to access all controls and DIP switches.
