ATTENTION:
• Do not connect power to the device until you have read the
• Ne branchez pas l'alimentation à l'appareil avant d'avoir lu les mises en garde
• Remove power from the system before making any connections.
• Mettez le système hors tension avant d'effectuer tout raccordement.
• The controller and the OCS 100C must share a common ground connection to avoid ground loops and a difference in
grounding potential.
• Le contrôleur et l'OCS 100C doivent partager une connexion de mise à la terre commune pour éviter les risques de
boucles de terre et une différence dans le potentiel de terre.
The OCS 100C requires 24 VDC to power. If the sensor is connected to a device that does not provide 24 VDC, use the included
PC 1224 power module:
Connect a 12 VDC power source to the 12 VDC input on the supplied PC 1224 power converter (see figure 6).
1.
Wire the PC 1224 24 VDC, 75 mA max connector to the black and red wires on the OCS 100C.
2.
A 12 VDC, 1.25 A max pass-through is available to power additional 12 VDC devices.

Power input
When wiring the blue wire 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 state and 0 VDC in the OFF state. Use the shared
black ground wire
Relay contacts could be used to trigger third party devices, such as HVAC, based on
occupancy.
Typically used for lighting applications. When wiring the gray wires of the OCS to
Extron products with Digital or FLEX Input ports, configure the ports as Input without
pull up. The output state will remain OFF 0 VDC when occupancy is detected but
there is high amount of ambient or natural light in the room. Only when there is low
or no ambient or natural light in the room and occupancy is detected will the output
state trigger ON 21 VDC. Use the shared black ground wire.
