The 734N Series was designed to have minimum impact on network performance. The
modules are supervised in the panel by exchanging two data packets every five seconds.
The payload of the data packets exchanged between the XR150/XR550 Series and the
modules is a very small 18 bytes. The total traffic for all supervision, including network
overhead, is roughly two kilobytes per minute per module. This would be equivalent to a
very small email message.
If required, all of the traffic between the modules and the panel can be completely
isolated from the rest of the existing network by connecting all of the modules and the
panel to the same switch, then connecting the switch to the remainder of the network.
All traffic between the modules and the panel would then be confined to the switch
where they are connected, while still allowing the panel to communicate with the central
station through the normal network.
The security of the modules is multi‑faceted. Most importantly, 734N Series modules are
single purpose network devices. All of the ports in the TCP/IP stack used in the modules
are disabled and allow no inbound connections. This prevents a potential intruder from
making any type of connection with the modules through the network. The modules
communicate with the control panel by establishing an outbound only connection to
the panel. All communication between the modules and the control panel is encrypted
using 128‑bit AES encryption. This is the same encryption standard approved and used
by the U.S. government, including the National Security Agency for encrypting secret
information.
734N Series encryption has not been evaluated by UL.
