Modular Fire Panel
Networked panels and remote keypads are known as "nodes".
A system comprises a number of networked panels and remote keypads.

The cabling between nodes and the maximum permissible cable length is also determined by
the choice of topology.

Bus topology
In bus topology, the CAN cable is always connected to the same CAN terminals:

NOTICE!
The maximum cable length is 1000 m, from the first to the last node. The cable length
depends on the cable cross section and the number of nodes.

Cable type for networking
The CAN connection is a two-wire connection (CAN-H and CAN-L). Three-wire connection
(CAN-H, CAN-L und CAN-GND) may be necessary in exceptional cases, e.g. with a high EMC

The number of detection points in a network is limited to 32,512.
The number of detection points per panel operated in a network is limited to 2032.
The number of nodes per system depends on the type of topology.
A node is either an MPC-xxxx-B Panel Controller or an FMR-5000 Remote Keypad.
The number of nodes in loop topology is limited to 32.
The number of nodes per CAN segment is limited to eight.
A CAN segment is the physical connection of a CAN line.
The number of nodes in bus topology is limited to eight, whether redundant or not.
With bus topology, there is one CAN segment in the non-redundant case and two CAN
segments in the redundant case. Consequently, each panel is physically connected to
each CAN segment.

CAN1 ⇒ CAN1 with non-redundant bus
Additionally, CAN2 ⇒ CAN2 with redundant bus.
In loop topology the CAN cable always runs from a CAN1 terminal to a CAN2 terminal
[CAN1 ⇒ CAN2],
meaning that a CAN segment consists of two nodes. The cable length depends on the
cable cross section and the number of nodes.
Due to the maximum number of 32 nodes and the maximum cable length of 1000 m
between nodes, a system can be installed with a total cable length of 32,000 m.
