734N Network Specications
The 734N was designed to have minimum impact on network performance. The 734N is supervised in the panel by
exchanging two data packets every ve seconds. The payload of the data packets exchanged between the XR100/XR500,
XR150/XR350/XR550 or the XR150INT/XR350INT/XR550INT Series and the 734N is a very small 18 bytes. The total trafc for
all supervision, including network overhead, is roughly two kilobytes per minute per 734N. This would be equivalent to a
very small e-mail message.
If required, all of the trafc 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 trafc between the 734N and the panel would then be conned 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. What this means
is that 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.
Packet Communication Outline:
• The 734N module establishes panel communication using the TCP/IP protocol.
• At start up, the 734N opens a TCP/IP connection that remains open indenitely.
• The socket can be closed by the 734N or panel after a time-out.
• The connection is re-established by the 734N after the time-out.
• A pair of supervision packets are sent every 5 seconds.
- The payload for each packet is 18 bytes and the total trafc, including overhead, is approximately 2 kilobytes
per minute for each 734N.
- Non-Supervision messages have a payload range of 18-50 bytes.
Compliance Listing Specications
UL Access Control
The access relay must be congured as fail-safe or fail-secure as determined by the local Authority Having Jurisdiction
(AHJ). This system is not intended to be used in place of listed panic hardware.
The power supply must be a listed commercial burglary/household re, power limited, Class 2 with a compatible voltage
range for the product. The 734N requires a listed 12 or 24VDC power source.
ULC Commercial Burglary (XR100/XR500 and XR150/XR350/XR550 Series Panels)
When using the zones of the 734N in a listed application, place the module in a listed enclosure and connect a DMP Model
307 Clip-on Tamper Switch to the enclosure programmed as a 24-Hour zone.
The 734N Access Control features have not been investigated by ULC.
The 734N zones can be used in a Low Risk application. For Medium or High Risk applications, refer to the Dual Zone
Protection diagram in the XR100/XR500 or XR150/XR350/XR550 Canadian installation guides.
