The 734N was designed to have minimum impact on network performance. The 734N is supervised
in the panel by exchanging two data packets every five seconds. The payload of the data packets
exchanged between the XR150/XR550 or the XR150INT/XR550INT Series and the 734N is a very
small 18 bytes. The total traffic for all supervision, including network overhead, is roughly two
kilobytes per minute per 734N. This would be equivalent to a very small email message.
If required, all of the traffic between the 734N(s) and the panel can be completely isolated from the
rest of the existing network by connecting all of the 734N modules and the panel to the same switch,
then connecting the switch to the remainder of the network. All traffic between the 734N 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 734N is multi-faceted. Most importantly, the 734N is a single purpose network
device. All of the ports in the TCP/IP stack used in the 734N are disabled and allow no inbound
connections. This prevents a potential intruder from making any type of connection with the 734N
through the network. The 734N communicates with the control panel by establishing an outbound
only connection to the panel. All communication between the 734N 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 encryption has not been evaluated by UL.
