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.

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 flashes when the infrared sensor detects occupancy.

• Retainer Ring — Holds the optional IR mask in place. Remove to access all controls and DIP switches.

Occupancy Sensor OCS 100C • Setup Guide (Continued)

• Black Timer Dial (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. If no motion is detected and the timer expires, then the sensor triggers OFF (low).

Use the black timer dial to set the amount of time before the sensor triggers OFF.

NOTE: B3 DIP Switch must be set to ON for Manual mode, in order to adjust the timer manually.

• Ranges from 8 minutes to 42 minutes.

• Full counter clock wise (CCW) = 8 minutes

• Full clock wise (CW) = 42 minutes

• To enter the test mode (8 second timer) follow the steps below:

1. Open the retainer ring.

2. Rotate the black timer dial to about midway (12 o’clock).

3. Return to minimum setting (full CCW).

4. The timer will remain in the 8 second test mode for 1 hour, then automatically reset to 8 minutes.

5. To manually force the timer out of the 8 second test mode, turn the timer adjustment approximately 1/16 inch clockwise. The setting is slightly above minimum (just above the 8 minute setting.

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

• Turn clockwise (CW) to increase sensitivity.

• Turn counter clockwise (CCW) to decrease sensitivity.

• The factory default setting is at 75%.

• Green Ultrasonic Range Dial — Adjust this dial to increase or decrease ultrasonic sensitivity.

• Turn clockwise (CW) to increase sensitivity.

• Turn counter clockwise (CCW) to decrease sensitivity.

• The factory default setting is at 50%.

NOTE: B4 DIP Switch must be set to ON for Manual mode, in order to adjust the Red Infrared Sensitivity Dial or the Green Ultrasonic Range Dial manually.

• Blue Photocell Dial — The photocell prevents the sensor from turning on when the area is adequately lit with natural light and 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, causing it to activate with less light.• Turn clockwise to increase photocell sensitivity, requiring brighter light to activate the sensor.• Factory default is 100% (full clockwise).• Full clockwise — Photocell sensor is disabled.• Range — 10 to 1000 LUX

NOTE: *Only use a mask if the PIR sensor needs to be blocked. Only one mask should be installed at any given time.

ATTENTION:• All structural steps and electrical installation must be

performed by qualified personnel in accordance with local and national building codes and electrical codes.

• Toute étape structurelle et installation électrique, doit être effectuée par un personnel qualifié, conformément aux codes du bâtiment, aux codes incendie et sécurité, et aux codes électriques, locaux et nationaux.

Blue Occupancy control output

Gray Occupancy and photocell control output

NOTE:• The gray wire is used when

the control system needs to know when the area is adequately lit with natural light and when motion is detected (for example, automatic lighting control through an Extron control system).

• When wiring the blue or gray wires of the OCS to Extron products with Digital or FLEX Input ports, configure the ports as Input without pull up. The sensor provides approximately 21 VDC in the ON (High) state and 0 VDC in the OFF (Low) state.

NOTE: Relay contacts could be used to trigger third party devices, such as HVAC, based on occupancy.

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 100C requires 24 VDC. If the sensors are connected to a device that does not provide 24 VDC, use the included PC 1224 power module:

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.

2. Wire the PC 1224 24 VDC 2-pole captive screw connector to the black and red wires on the OCS 100C.

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

Troubleshooting

Problem Possible Cause Test Solution

Sensor remains on. Constant noise. Reduce both green and red knobs by 1/4 turn and remove noise source.

Move sensor to a less noisy area within the room.

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

Hallway traffic turns sensor on.

Infrared sensor can see into the hallway.

Put sensor in timer test mode and walk the hallway.

Move sensor, so it cannot see into the hallway.
