NETWORKING
The Fusion utilises CAN (controller area networking) Protocol to provide a fast reliable network of up
to 16 control panels and / or repeater panels.
Up to 1,000 metres of cable can be used over the network. The recommended cable for use with
Control panel networking is a Screened twisted pair fire resistant cable.
Typical cables for networking use include:-
Note:- Belden 8760 1 pair cable can be used but is not suitable where a fire resistant cable is
required.
The CAN bus requires to be terminated at the furthest ends by 120R (ohm) resistors, these are
supplied ready fitted to the FSB17 circuit board just under the CAN BUS terminals (position R177).
Where more than two panels are on a single network the resistors should be removed from the
panels other than the two furthest. Using a fine pair of wire cutters to snip the resistor legs. CAN bus
connections are labelled A and B. All A terminals are connected together and all B terminals. They
can be connected in any wiring configuration but not in a loop. Signal levels around 5 volts would
typically be seen when the bus is
running.
Setting up network
Each panel in the network must be set with a unique address starting at 0 this is set on the address
switches on each panel in turn (refer to page 24 for details). Each panel has a parameter in the
engineering options menu ‘set system parameters’ option No 3 to set the number of remote panels.
This quantity needs to be set on each panel to represent the number of other panels fitted in the
system e.g. in a network of five panels this figure will be set to 4 in each case. Once set correctly the
system will be in the quiescent state.
Network diagnostics
As each panel operates on a peer to peer basis i.e. independently. All panels monitor each other.
Each panel sends a regular ident pulse which is monitored by all others. If an error is present it will
be enunciated on all panels. A fault message is given if a panel is lost or if a panel is seen on the
network which is not expected. Also the integrity of the message packets received is constantly
monitored. If data corruption is occurring (perhaps due to cabling faults) this will be enunciated as a
‘network message error’ along with the number relating to the panel affected. (Note due to display
restrictions panels 10 to 15 are indicated by letters A=10, B=11, C=12, D=13, E=14, F=15,) This
indication may also be given if there are two identical addresses on the network. To clear the fault
check all address settings or cable integrity.
