Packet Communication
• The 734N module establishes panel communication using the TCP/IP protocol.
• At start up, the 734N opens a TCP/IP connection that remains open indefinitely.
• 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 traffic, including overhead, is
approximately 2 kilobytes per minute for each 734N.
- Non-Supervision messages have a payload range of 18-50 bytes.
