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.
• Ultrasonic Sensors — Detect movement in the room, based on
ultrasonic waves.
• Green LED (status indicator) — Flashes when the ultrasonic
sensors detect occupancy.
• Infrared/Photocell Sensor and Lens — Diffracts the incoming
light and directs the light to the infrared/photocell sensor.
• Red LED (status indicator) — Flashes when the infrared sensor
detects occupancy.

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.
If no motion is detected and the timer expires, then the sensor triggers OFF (low). In Manual mode, set the B1 and B2
DIP Switches together, as shown in the table above, to set the amount of time before the sensor triggers OFF.
NOTE:
• The B1 and B2 DIP Switches are 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.
• Blue Timer Test Button —
• To enable an 8 second timer test mode, push the blue button once. The test mode will last for 1 hour, and then
automatically resets to the dip switch settings.
• To cancel the 8 second test mode, push and hold the blue button until the red LED ashes, returning the OCS to the
settings dened by the dip switches.
• 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.
• The factory default setting is at 75%.
• Green Ultrasonic Range Dial — Adjust this dial to increase or decrease ultrasonic sensitivity.
• Turn counter clockwise (CCW) to decrease sensitivity.
• Turn clockwise (CW) to increase 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 — 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 counter clockwise — 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 frequency of reected ultrasonic
waves, caused by movement within the space.
NOTE: See Troubleshooting on page6 if you experience false triggers.

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, congure 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100W 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 (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 Solution
Sensor remains on. Constant noise. Reduce both green and red
knobs by 15% and remove
noise source.
Move sensor to a less noisy
area within the room.
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 sensor in timer test mode
and walk the hallway.
Move sensor, so it cannot see
into the hallway.
