The following figure shows the typical wiring for a supervised input.
Figure 7: Typical Supervised Input Wiring Diagram
The figure above shows standard 2,200 ohm resistors. The NetAXS™ panel accepts
1,000, 2,200, 4,700, or 10,000 ohm values. Note that both resistors must have the
same value. See the NetAXS™ Access Control Unit User’s Guide for instructions on
selecting resistor options.
In addition, the Tamper and External Power Fail, as well as the Reader and Panel
tampers can be supervised and capable of being used as additional inputs if the default
functionality is not needed. They also share a single common.
The wire used for the inputs should be shielded and cannot exceed 30 ohms over the
entire length of the cable. Remember that the distance from the panel to the door must
be doubled to determine the total resistance.
