Figure 2 Smart Reader pigtail description
Recommended maximum cable length:
300 ft (91 m) with CAT6 or 500 ft (152 m) if
two wire pairs are used for GND and VIN (power).
For shielded wiring:
Connect one side of the drain wire (the shield around the wires)
to the GND terminal on the SDC. Both the shield and the GND wire can share the same
GND terminal. Do not connect the other side of the shield to anything.
For standard reader installation:
We recommend that you install a 1-Gang 20 CU
box in order to flush-mount the reader. Alternatively, the reader may also be surface
mounted with the included back plate.
Note:
For elevators, all relays and readers must be connected to the same SDC. If you
need more than four access controlled floors or readers, add the Openpath Elevator
Expansion Module.
WARNING:
Always remove power from the SDC and locking hardware when wiring
readers and other devices. Failure to do so can damage the SDC.
