PC 1224 Wiring
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 «
» de la page suivante.
•
Remove power from the system before making any connections.
•
Mettez le système hors tension avant d’effectuer tout raccordement.
•
The controller and the OCS 100W must share a common ground connection to avoid ground loops and a difference in
grounding potential.
•
Le contrôleur et l’OCS 100W 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 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, (see figure 8).
2.
Wire the PC 1224 24 VDC, 75 mA max connector to the black and red wires on the OCS 100W.
A 12 VDC, 1.25 A max pass-through is available to power additional 12 VDC devices.

Occupancy control output
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.

output
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.
