Power for the reader connection (VDC) is derived from the power input (VIN) for the AAN-4 and is distributed
between the four reader connections. Thus, voltage to the reader power connection will roughly equal the
voltage supplied to the AAN-4 power input. There must be sufficient power to supply the load of all readers
as well as for the AAN-4 itself (+12 to +24VDC @ 250 mA). If the readers have a greater total power
requirement, or if there are other wiring concerns, external power supplies should be used to power the
readers. In this case, only connect the reader power lines to the external power supply; do not connect the
reader to two power supplies.
For basic operation of the reader, at a minimum the Data 0 and Data 1 wires must be connected from the
reader to the AAN-4 and power supplied to the reader. LED and beeper control lines do not have to be
connected, but in this case, the LEDs and beeper may not function on the reader.

Figure 3.5 AAN-4 Card Reader and Input Wiring.
The AAN-4 supports up to four card readers which
are connected in standard configuration. For each reader connection there is a door contact input, exit push
button input and one axillary input which is displayed here connected to a motion sensor. Refer to the
Terminal Connectors table and the installation instructions for the reader that will be used for exact wiring
positions.
