efailure of any power amplifier.

8.3Indication of faults related to the transmission path to the CIE (option with requirements)

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.

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.

8.4Indication of faults related to voice alarm zones (option with requirements)

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.

by means of a separate light emitting indicator per zone
and/or an alphanumeric display.	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	14.4 Program monitoring (see also Annex C)
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:

aa 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;

ba system fault shall be audibly indicated. This indication may be capable of being silenced.

8.6 Audible indication

8.6.1The 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.

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.
