Openpath ACCESS CONTROL SYSTEM Installation Manual page 11

WIRING INFORMATION
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 ACU. 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 ACU. If you
need more than four access controlled floors or readers, add the Openpath Elevator
Expansion Module. See
WARNING: Always remove power from the Smart Hub and locking hardware when
wiring readers and other devices. Failure to do so can damage the ACU.
