Clause / Requirement Compliance Signature
a an indication at least common to any
power supply fault resulting from:
The mains and backup power of all
Plena Voice Alarm System
elements are supervised
individually, depending on
configuration. The controller and
routers monitor the power sources
on a system level.
– a short circuit or an interruption in
a transmission path to a power
supply (item L of Figure 1 of
EN 54-1), where the power supply
is contained in a different cabinet
from that of the VACIE, and
– the power supply faults as
specified in EN 54-4;
b an indication at least common to any
earth fault of less than 50 kW is
capable of affecting a mandatory
function, and which is not otherwise
indicated as a fault of a supervised
function;
All 100V lines of the Plena Voice
Alarm System are supervised
individually for earth faults (i.e.
connections to earth with a
leakage resistance of less than 50 k
Ohm).
c an indication of the rupture of any
fuse within the VACIE, or the
operation of any protective device
within the VACIE which is capable of
affecting a mandatory function in the
fire alarm condition;
Every rupture of a fuse or the
operation of a protected device
that affects a mandatory function
will result in a fault since the
mandatory functions are
supervised. The reported fault is as
close to the located defect as
possible. E.g. a mains related fault
is reported as a mains fault and an
amplifier defect is reported as
defect for that amplifier.
d an indication of any short circuit or
interruption, at least common to all
transmission paths between parts of
the VACIE contained in more than one
cabinet, which is capable of affecting
a mandatory function and which is not
otherwise indicated as a fault of a
supervised function.
All transmission paths of the Plena
Voice Alarm System are
supervised.
All control input contacts of the
Plena Voice Alarm System can be
supervised for shorts and
interruptions.
Analog audio connections to
external parties can be supervised
by pilot tone supervision.
