4.2 Reader Wiring
Each reader port supports a single 12-volt reader with Wiegand output format. Power
to the readers is shared with the AUX Power ports TB3 and TB14. The maximum
power draw is 600 mA for readers and AUX Power combined.
To fully utilize each reader port, a shielded 7-conductor cable (18-22 AWG) is
required. If the optional reader buzzer feature is not needed, you can use the standard
six-conductor cable (HAS part number NC1861-BL). The cable shield should be
grounded at the panel only. Grounding at both ends can cause ground loops which can
be disruptive. The maximum recommended length of wiring is 500 feet per reader.
4.3 Supervised Input Wiring
The supervised inputs are located on TB4 and TB13 (Figure 7 on page 15). Input 1
through Input 8 may be configured for normally open or normally closed contacts as
supervised or non-supervised. Inputs 13 and 14 are on TB8. All eight inputs have
default functions, but they can be configured for general purpose inputs.
The following table identifies the default function for each terminal position.
