2-Wire devices wiring

Starting with the Akuvox AK-NS-2 2-wire IP network switch.

There is a max of 6 2-wire devices to be connected on one AK-NS-2 2-wire IP network switch.

This can be in cascade mode or parallel Akuvox 2-wire IP intercom devices.

Note: Only one outdoor unit per two-wire hub.

AK-C313W-2 Monitor wiring

The AK-C313W-2 monitor has two wire connections and one Ethernet.

The AK-C313W-2 can be used as a hub to connect up to 6 devices, or connected to the AK-NS-2 2-wire IP network switch.

Note: Only one outdoor unit per cascade

2-Wire Door unit wiring

The AK-R20K-2 and AK-R20A-2 has only one relay, and Wiegand in or output.

Warning: When you connect a device containing a coil, such as a relay or an electromagnetic lock, it is necessary to protect the intercom against voltage peak while switching off the induction load. For this way of protection, we recommend a diode 1 A / 200 V (included in the accessories) connected antiparallel to the device.
