4-3.5.3 Continuous Screen
The screen on a network needs to be continuous. That means it remains unbroken along its entire
length. As there is one ‘S’ terminal on a typical network device both the Global and Net screens are to
be connected to this tie terminal.
4-3.5.4 Innotech Net / Global Comms Connections
When other controllers are added to the network they must be installed in a manner that does not
interrupt the integrity of the network. A lot of current devices will have the so earth option and
are fully isolated from the factory. There is no issue mixing the current style earth connection with
previous models of hardware on the network if the following rules are applied.
For any so earth type device connected to a primary network there are some general rules for
connection.
•Do not break the continuity of the screen
•Use the ‘S’ terminal for both the entering and leaving screen termination
•You must earth the system at a single bonded earth point. This is regardless of the number of so
earth points connected
•Attempt to ensure the net and global networks are the same length and follow the same path
