Two wiring options are possible:
• Ring configuration
• Bus configuration
Ring configuration
Ring network configuration is recommended as it provides for redundancy in the
transmission path.
For ring configuration (Class A), use both ports to connect all network boards or
control panels to form a ring, as shown below.

Bus configuration
Note:
To be compliant with EU regulations, use this network configuration only in
cases where the detection zones and mandatory EN 54-2 output functions
(sounder and fire routing outputs) are not remote between panels.
Bus network configuration is not normally recommended, as it does not provide
for redundancy in the transmission path.
For bus configuration (Class B), connect control panels as shown below.
