Control Unit / TLON Network
4.1
The TLON network
An installation (a system) can be
one control unit (c.i.e.)
or up to
30
control units
connected in a
TLON Network
.
In a TLON Network each control unit works independent but has
nevertheless total access to all information in the system.
NOTE!
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 c.i.e.
When the "Fire door closing" function is used, the alarm points
and their "belonging" output must be connected to the same c.i.e.
When the interlocking function is used, the input, the output and
the Interlocking Combination (area-point) must be in / connected
to one c.i.e. An input and an output can only be used in one
Interlocking combination.
When the AAF function is used, all devices within the same AAF
zone must be connected to the same c.i.e.
4.2
Single TLON Network / redundant TLON
Network
The EBL512 G3 system can be build up as a single TLON Network or
a redundant TLON Network.
In the single TLON Network, one TLON connection board (1590) has
to be plugged in each control unit whereas in the redundant TLON
Network, two TLON connection boards have to be plugged in each
control unit.
In the single TLON Network, only one network is available (Network
no. 0) but in the redundant TLON Network, two networks are
available (Network no. 0 and Network no. 1).
The redundant TLON Network supports full functionality also in case
of a network fault (i.e. open circuit or short circuit) in one of the
TLON networks. A fault in one of the TLON Networks generates the
following fault:
FAULT: Control unit xx has no contact
with control unit xx, network x
Where network x = Network no. 0 or Network no. 1.
