Praesideo 4.3
Clause / Requirement
d
any short-circuit or interruption in the transmission path
between the VACIE and fire alarm devices when used
(see 7.8).
e
failure of any power amplifier.
8.3 Indication of faults related to the transmission path to
the CIE (option with requirements)
The VACIE may have provision for an indication of faults
related to the transmission path to the CIE. In this case, the
short-circuit or interruption of the transmission path to the
CIE shall be indicated by means of a separate light emitting
indicator and/or an alphanumeric display.
8.4 Indication of faults related to voice alarm zones (option
with requirements)
The VACIE may have provision for an indication of faults
related to voice alarm zones. In this case the short-circuit or
interruption of a voice alarm transmission path between the
VACIE and the loudspeakers in that zone shall be indicated
by means of a separate light emitting indicator per zone
and/or an alphanumeric display.
8.5 System fault
A system fault is a fault as specified in 14.4 Program
monitoring (see also Annex C)or 14.6 Monitoring of memory
contents in the case of software controlled VACIE. A
system fault may prevent requirements of this European
Standard, other than those specified below, from being
fulfilled. In the event of a system fault at least the following
shall apply:
a
a system fault shall be visibly indicated by means of the
general fault warning indicator and a separate light
emitting indicator on the VACIE. These indications shall
not be suppressed by any other functional condition of
the VACIE and shall remain until a manual reset and/or
another manual operation at access level 2 or 3;
b
a system fault shall be audibly indicated. This indication
may be capable of being silenced.
8.6 Audible indication
8.6. 1 The audible indication of faults required in 8.2 shall be
capable of being silenced manually at access level 1 or 2 at
the VACIE. The same manual operation may be used as for
silencing the voice alarm condition.

Compliance
The Praesideo system does not offer this functionality
directly: control inputs are supervised, but control outputs
are just voltage free relay contacts. The installer must
create a feedback signal (corresponding to the
transmission path status between the Praesideo system
and the fire alarm device) to a supervised input contact of
the Praesideo system.
All Praesideo power amplifiers are supervised for overload,
overheating, short-circuit, ground short and amplifier
defect.
All input contacts of the Praesideo system can be
supervised for short and interruption.
Open Interface connections are supervised through keep-
alive messaging.
Faults related to the transmission path to the CIE are
therefore individually reported and can be inspected using
the front panel menu of the network controller or the
logging application. The faults are also reported through
the general fault warning indication.
Faults that occur in the Praesideo system are reported per
defective input or output for fault allocation. When an
individual fault is reported the name of the event originator
(i.e. the location of the fault) is provided.
The installer must give audio outputs that are assigned to a
zone, clear names, identifying the zone. This way the event
originator field in the indication of the individual fault will
immediately show in which zone the fault has occurred.
Praesideo provides zone fault status indicators, assigned to
keypad modules. One or more zones can be configured to
control such an indicator.
Praesideo is compliant.
14.4 Program monitoring (see also Annex C)
System faults are individually reported by the Praesideo
system and can be inspected using the front panel menu of
the network controller or the logging application.
Faults are also reported through a general fault warning
indicator, connected to a control output that is configured
as Fault alarm buzzer or visual Fault alarm indicator.
Both the individual fault indicator of each system fault and
the general fault warning indicator are not suppressed by
any other functional condition of the Praesideo system.
A control output contact of a Praesideo system component
can be configured as Fault alarm buzzer. This output
contact can be connected to a buzzer. This way all faults,
including system faults, are indicated audibly.
The Fault alarm buzzer can be silenced by acknowledging
all faults via a key or control input that is configured as Fault
acknowledge key. The control output for the visual Fault
alarm indicator is only deactivated upon resolving and
resetting all fault conditions.
Praesideo is compliant.
The Fault alarm buzzer can be silenced by acknowledging
all faults via a key or control input that is configured as Fault
acknowledge key. Individual faults can also be
acknowledged from the front panel menu of the network
controller or via the Open Interface.
