d any short-circuit or interruption in the transmission
path between the VACIE and fire alarm devices when
used (see 7.8).
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.
e failure of any power amplifier. All Praesideo power amplifiers are supervised for
overload, overheating, short-circuit, ground short and
amplifier defect.
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.
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.
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.
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 kits. One or more zones can be configured to
control such an indicator.
8.5 System fault Praesideo is compliant.
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:
14.4 Program monitoring (see also Annex C)
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;
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.
b a system fault shall be audibly indicated. This
indication may be capable of being silenced.
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.
8.6 Audible indication Praesideo is compliant.
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.
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.
