Door Access Control
The reader expander provides access control functionality onboard without the requirement for additional
hardware.
The reader expander allows the connection of 2 Wiegand devices to control 2 doors (entry or exit only), or it can
be configured in multiplex mode to allow 4 Wiegand devices controlling 2 doors, giving the flexibility of entry and
exit readers. Alternatively, the two reader ports can be independently configured to connect RS-485 readers.
The recommended cable types for RS-485 are:
⦁
Belden 9842 or equivalent
⦁
24 AWG twisted pair with characteristic impedance of 120ohm
The recommended cable types for Wiegand are:
⦁
22 AWG alpha 5196, 5198, 18 AWG alpha 5386, 5388
Important:
⦁
The card reader must be connected to the module port using a shielded cable.
⦁
The shield must only be connected at one end of the cable in the metallic enclosure (frame grounded).
⦁
Do not connect the cable shield to an AUX-, 0V or V- connection on the module.
⦁
Do not connect the cable shield to any shield used for isolated communication.
⦁
The reader and cable shield wires must be joined at the reader pigtail splice.
⦁
Do not join the shield and black wires at the reading device.
⦁
Do not terminate the reader shield wire inside the reader.
Note: The reader and cable shield wires must be joined at the reader pigtail splice for all MIFARE capable ICT card
readers. Older readers which are internally grounded and third-party readers do not require the shield wires to be
joined. For further information, contact ICT Technical Support.
Always refer to the card reader manufacturer for detailed installation guidelines.

All UL listed ICT readers are shipped with single LED mode set as default and are fully compatible
with the Protege system.
RS-485 Reader Locations
As two RS-485 readers can be connected to the same RS-485 reader port, configuration of the
green
and
orange
wires uniquely identifies the reader, and determines which is the entry reader and which is the exit reader.
