Figure 2 Redundant fibre optic network for more than 10 control panels
When a number of control panels less than 10 is required in a TLON network, the traffic
will not be very heavy and the LPR10 router may not be required as shown in Figure 3
Figure 3 Redundant fibre optic network for up to 10 control panels
The type of fibre optic repeater is dependent on the cable type e.g. single or multi-mode,
distance between C.U.’s, etc. Care must be taken when selecting the repeater type.
Note
: A TLON network of FT1020G3 control panels may consist of fibre optic segments
and twisted pair segments.
3.4.3
TCP/IP TLON network
LonWorks Internet server such as iLon 600, can be used as an internet (or any IP-based
LAN or WAN) pathway for TLON.
The transition from TP/FT10 to IP network opens the opportunity to use a large range of
infrastructure products e.g. fibre optic converters.
Note
: a network of fire alarm system is always connected via a dedicated network wiring,
great attention must be taken when choosing an IP network as a pathway for TLON
should be used for autonomous Control Units only. The efficiency of the IP based
communication is dependent on the efficiency of the infrastructure of the IP network.
