Clause / Requirement

8 Fault warning condition

8.1 Reception and processing of fault signals

8.1.1The VACIE shall enter the fault warning condition when signals are received which, after any necessary processing, are interpreted as a fault.

8.1.2The VACIE shall be capable of simultaneously recognizing all of the faults specified in 8.2 and, if provided, in 8.3 unless this is prevented by:

•the presence of an alarm output signal on the same voice alarm zone, and/or

•the disablement of the corresponding voice alarm zone or function, and/or

8.1.3The VACIE shall enter the fault warning condition within 100 s of the occurrence of any fault, or the reception of a fault signal or within another time as specified in this European Standard or in other parts of EN 54.

8.2 Indication of faults in specified functions

8.2.1The presence of faults in specified functions shall be indicated on the VACIE without prior manual intervention. The fault warning condition is established when the following are present:

aa visible indication by means of a separate light emitting indicator (the general fault warning indicator);

ba visible indication for each recognised fault as specified in 8.2.3, 8.2.4, 8.3 (if provided), 8.4 (if provided) and 8.5 and

can audible indication, as specified in 8.6.

8.2.2If the indication is on an alphanumeric display, which cannot simultaneously indicate all of the faults because of its limited capacity, at least the following shall apply:

athe presence of fault indications which have been suppressed shall be indicated;

bsuppressed fault indications shall be capable of being displayed by means of a manual operation at access level 1 or 2 which interrogates only fault indications.

8.2.3The following faults shall be indicated by means of separate light emitting indicators and/or an alphanumeric display:

aan indication at least common to any power supply fault resulting from:

1 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

2the power supply faults as specified in EN 54-4;

Compliance Signature

Praesideo is compliant.

When the Praesideo system receives a supervision fault signal (i.e. detects a fault in the system), the fault warning condition is entered until this state is explicitly reset.

All Praesideo system faults are handled (acknowledged and reset) individually. Also, the Praesideo system is capable of recognizing all of its system faults simultaneously. The Praesideo system is able to recognize faults in a voice alarm zone even when there is an alarm output signal on the zone.

Optional disablement of voice alarm zones or functions is not implemented in Praesideo.

The Praesideo system recognizes and reports all faults within 100 seconds.

Praesideo is compliant.

The Praesideo system provides a visible indication when it is in the fault warning condition via the fault LED of the call stations, output contacts, key indicators of call station keys, the fixed fault output contact of the network controller and the front panel menu of the network controller.

The installer must mount a yellow (flash) light to indicate the fault warning condition, clearly visible from the front side of the rack, behind the glass door of the rack.

The Praesideo system offers two ways of visual indication of individual faults: via the front panel menu of the network controller and via the Praesideo logging application.

The Praesideo system provides an audible fault indication when it is in the fault warning condition via output contacts and the fixed audible fault output contact of the network controller.

The network controller alphanumeric display is used to indicate the fault warning condition and all individual faults.

The normal display information of the network controller is automatically overruled when there are faults present, i.e. when the system enters the fault warning state. The display of the network controller indicates the number of faults present.

The individual faults are presented in the ‘Faults’ menu of the front panel menu of the network controller. Manual operation is needed to display and navigate through the individual faults. Each individual fault is shown in a submenu of the ‘Faults’ menu.

Faults of the supervised items are detected and reported through the general fault warning indication. Additionally all faults are reported individually as well and can be inspected using the network controller front panel menu and the logging application.

The mains and backup power of all Praesideo system elements are supervised individually.
