MEW01351 Rev: - Planning Instructions Fire alarm system EBL512 G3, V1.1.x
NOTE!
In a system where each control unit is independent of the other (i.e.
each control unit works like a "standalone" control unit) a single
TLON Network may be sufficient. To maintain security, in this case:

All control units shall be of type 5000, i.e. including front panel.

The alarm points and their "belonging" outputs shall be connected
to the same control unit.

If fire alarm routing equipment (Fire brigade tx) shall be used,
each control unit in the system shall be able to activate a fire
alarm routing equipment independent of the other control units.
In all other cases and for highest security, a redundant TLON Network
shall be used.
(According to EN54-13, 4.3.1.2: A single fault on a transmission
path connecting one CIE to another CIE, shall not adversely affect the
correct functioning of any part of the networked system.)
