The OCS 100W is a wall-mounted occupancy sensor that incorporates ultrasonic (US) and passive infrared (PIR) into a dual­technology 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.

• Green LED (status indicator) — Flashes when the ultrasonic

sensors detect occupancy.

• Infrared Sensor and Lens — Diffracts the incoming light and

directs the light to the infrared sensor.

• Red LED (status indicator) — Flashes when the infrared sensor

detects occupancy.

• Push and hold until the red LED ashes to return the 8 second timer to the dip switch timer settings.

• Red Infrared Sensitivity Dial — Adjust this dial to increase or decrease infrared sensitivity.

• Turn counter clockwise (CCW) to decrease sensitivity.

• Turn clockwise (CW) to increase sensitivity.

• Factory default is 75%.

• Green Ultrasonic Range Dial (see figure2 on the previous page) — Adjust this dial to increase or decrease ultrasonic

sensitivity.

• Turn counter clockwise (CCW) to decrease sensitivity.

• Turn clockwise (CW) to increase sensitivity.

• Factory default is 50%.

• Blue Photocell Dial — Photocell prevents the sensor from triggering on when the area is adequately lit with natural light and

when motion is detected. The sensor must be mounted directly over an area that is representative of the average, natural
room lighting. Before setting the photocell control, wait until the natural light is brightest (optional). Adjust this dial to increase
or decrease photocell sensitivity.

• Turn counter clockwise to decrease photocell sensitivity.

• Turn Clockwise to increase photocell sensitivity.

• Factory default is 100% (full clockwise).

• Full CW — Photocell is disabled.

• Range — 10 to 1000 LUX

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 trafc,
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. US sensors trigger in response to changes in the pitch of reected ultrasonic waves,
caused by movement within the space.

NOTE: See Troubleshooting on page5 if you experience false triggers.

PC 1224 Wiring

ATTENTION:

• Do not connect power until you have read the ATTENTIONS: notices on the next page.

• Ne branchez pas l’alimentation avant d’avoir lu les mises en garde «ATTENTIONS» de la page suivante.

• Remove power from the system before making any connections.

• Mettez le système hors tension avant d’effectuer tout raccordement.

The OCS100W requires 24 VDC. If the sensors are connected to a device that does not provide 24 VDC:

1. Connect a 12 VDC power source to the 12 VDC input on the supplied PC 1224 power converter,

using a 2-pole captive screw connector (see image on the right).

2. Wire the PC 1224 24 VDC 2-pole captive screw connector to the black and red wires on the

OCS100W.

A 12 VDC pass-through is available to power additional 12 VDC devices.

Troubleshooting

Problem Possible Cause Test Result

Sensor remains on. Constant noise. Reduce both green and red

knobs by 15% and remove
noise source.

Sensor remains on too long. Timer setting too high. Check dip switch settings. Reduce timer setting.

Hallway trafc turns sensor
on.

Infrared sensor can see into
the hallway.

Put in timer test mode and
walk the hallway.

Move sensor to a less noisy
area within the room.

Move the sensor, so the
sensor cannot see into the
hallway.
