Chapter 7: Peer-to-peer 3 protocol
112 ZP3 Fire Control Panel Installation, Commissioning, and Maintenance Manual
This chapter covers the new features and enhancements of software 71910
Version 3.04 (EN 54 ZP3 Fire Panel), which was released on 01 August 2003.
Panel Software 3.04 makes use of a new data structure. This new structure
relates to device messages and zone messages.
Use Planner version 3.0.0.59 or higher to ensure that the structure is correct.
Previous Planner projects or saved files are converted automatically to the
correct structure when opened with Planner 3.0.0.59 or higher.
The most notable new feature is the Peer-to-Peer 3 Protocol (P2P3), which
allows up to 255 network nodes on a single multidrop RS-485 communication
link. Although this capability is apparent, a network of 100 nodes is deemed the
maximum, as this is the maximum extent to which the system has been tested.
Since version 3.00, the protocol has been reworked to deliver multiple
commands and events in a single data packet. This results in larger packets and
quicker overall performance when the system gets busy. Version 3.00 and 3.04
panels will therefore not communicate correctly with each other.
During upgrade, we recommend that the version 3.04 panels have their network
communications disabled. This can be done either by physically disconnecting
them or splitting them into subnetworks of new and old or by using the new Panel
Comms Disable feature described on the next page.
Keep the network communications disabled until all the old version 3.00 software
has been replaced.
Sound and silence command and status report handling has been improved to
minimize an older event from being reported after a newer command.
The status block fetched by Maestro now includes a “panel comms disabled”
status (block 15).
