Redundancy in distributed system
In a distributed system (i.e. two or more control units in a TLON
network), with fire alarm routing equipment in only one of the control
units, it is possible to indicate fire alarm and to activate the output for
fire alarm routing equipment (fire brigade tx) even in case of a single
open circuit (cut-off) or single short circuit in the TLON network.
EBL512 G3 units with the S/W EBL512 G3 United version 2.7.x
makes it possible to use EBL512 G3 units (5000 / 5001) together with
EBL512 units (1548 / 1549 / 1550), in a TLON Network, i.e. a
mixed
system
.
NOTE!
This function is only valid for the non-programmable standard output
for fire alarm routing equipment (fire brigade tx). The programmable
outputs have no benefit of this function. The system planner
(commissioner) should for any output, avoid such control expression
(trigger conditions) that for the correct function is dependent on no
fault on the TLON network.
There are two ways of system build-up:
Master and slaves
individually connected to the master.
Master and several control units
connected in parallel and
connected to one input in the master.
NOTE!
An EBL512 G3 control unit cannot be the master
