Network requirements
An Ethernet connection with DHCP must be used to connect the ACU to the Local Area Network (LAN). You may
also need to configure firewall settings to communicate with the Avigilon Alta access control system, which
uses the following outbound ports:
l
TCP port 443
l
UDP port 123
Note: If using an external DNS server, the outbound UDP port 53 must also be open.
To support Wi-Fi unlocking from the mobile app, the inbound TCP port 443 of the ACU must be available from
within the LAN. Inbound port forwarding on the router, firewall, or NATdevice is not required.
The ACU also supports Wi-Fi connections. Refer to Configure network settings using Open Admin app on
page65.
Selecting a backup battery
While not required, a backup battery is recommended in case of power outages. 12V supplies require one 12V
backup battery. 24V supplies require two 12V batteries in series. The size of batterydepends on your setup and
how long you want to power the system.
