TLON Network
For further details refer to "TLON Technical / Operation Manual" M437, see also chapter
"TLON connection board 5090" page 50.
3.1
FT1020G3 TLON network
FT1020G3 system can be one Control Unit (CIE) or up to 30 Control Units connected in
a TLON Network.
In a TLON Network, each Control Unit operates independently but has nevertheless total
access to all information in the system.
In a system with two or more Control Units in a TLON Network, pay attention to the
following:
A zone must not be distributed over the system, i.e. all alarm points in a zone
have to be connected to one CIE
When the "Fire door closing" function is used, the alarm points and the outputs
activated by these alarm points must be connected to the same CIE
When the interlocking function is used, the input, output and the Interlocking
Combination (area-point) must be connected to one CIE. An input and an output
can only be used in one Interlocking combination.
When the AAF function is used, all devices within the same AAFC zone must be
connected to the same CIE.
3.2
Redundant TLON Network
The FT1020G3 system can be build up as a single TLON Network or as a redundant
TLON Network.
A single TLON Network is only allowed when more than one main board (5010) are
mounted in the same cabinet. In this case, only one TLON connection board (5090) is
required to be plugged in the main board. Whereas in a distributed systems, redundant
TLON Network must be used, 2 TLON connection boards (5090) have to be used in each
Control Unit.
In the single TLON Network, only one network (Network no. 0) connection is used but in a
redundant TLON Network, two networks connections (Network no. 0 and Network no. 1)
must be used. In normal conditions, Network no. 1 is only supervised / monitored until
Network no. 0 fails to establish the communications between the control panels.
The redundant TLON Network supports full functionality. In case of a network fault (i.e.
open circuit or short circuit) in one of the TLON networks, a fault for this TLON Network is
generated as shown in the following fault message:
Where network x = Network no. 0 or Network no. 1.
3.3
Routers
In a TLON network, it is recommended to use TP/FT routers in order to split the TLON
network into separate FTT-10 channels / segments with the following objectives:
Provide galvanic isolation between TLON segments.
FAULT: Control Unit xx has no contact
With control unit xx, network x
