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.
Caution:
Grounding at both ends can cause ground loops which can be disruptive.
Caution:
Alarm units and systems.

4.6 NX4L1 Control Output Wiring

The NX4L1 provides a Power Distribution Output circuit board that is pre-wired to
the eight relays on the control panel. Each panel relay controls the correspondingly
numbered Power Distribution Output relay.
Relay 1 is defaulted for control of the Door 1 lock, Relay 2 is defaulted for the control
of the Door 2 lock, Relay 3 is defaulted for the control of the Door 3 lock, and Relay 4
is defaulted for the control of the Door 4 lock. Relays 5-8 are used as auxiliary relays.
Refer to the NetAXS Access Control Unit User's Guide for details on controlling the
relay operations. The NX4L1 is wired to enable the internal nominal 24 VDC power
supply to be used to power the access control door strikes/locks or other auxiliary
loads. The voltage range of the relay outputs is 23.5 VDC to 25 VDC. If the
application requires a separate supply, refer to the Power Distribution Output board
installation manual for details.
