By persons who are trained and authorized by the manufacturer to either repair the VACIE or alter its firmware, thereby changing its basic mode of operation.
The minimum requirements for accessibility are defined in 13.6. Only access levels 1 and 2 have a strict hierarchy. Examples of special procedures for entry to access level 2 and/or to access level 3 are the use of:
It may be acceptable that the entry to access level 4 requires only a simple tool, such as a screwdriver, after access level 2 or 3 has been reached. For example, the manufacturer may declare in his documentation which parts of the VACIE is not user serviceable, and the entry to access level 4 may then be controlled by management of the user. It is also considered acceptable to use external tools to carry out certain functions at access level 3, e.g. to program site-specific data.
A.2.6 Additional access levels
It may be desirable in certain circumstances that the VACIE has additional access levels within access level 2, or access level 3 (e.g. 2A and 2B), which would permit different classes of authorized user to have access to a selected group of controls or functions. This is not forbidden by this European Standard. The exact configuration will depend on the type of installation, the way the VACIE is used, and the complexity of the functions provided.
Optional functions with requirements and alternatives B.1 Optional functions with requirements
This European Standard specifies mandatory functions and options with requirements (see 4.1.1). A VACIE complying with this European Standard will need to fulfill the requirements of all of the mandatory functions, together with the requirements of those optional functions that are provided. The options described in this European Standard are currently used in the CEN member states and have been incorporated into this European Standard in order to comply with application guidelines. They may also be called up in national codes of practice. Optional functions of VACIE and their relevant clause numbers are listed in Table B.1.
B.2 Alternatives
In addition, alternatives are offered in this European Standard. Examples of these are:
— automatic or manual reset of the fault warning condition;
— indications by means of separate light emitting indicators or on an alphanumeric display;
— access level 1 or 2 for certain functions.
The choice of an alternative is entirely up to the manufacturer. These alternatives are equivalent solutions in this European Standard.
Design requirements for software controlled VACIE
C.1 The VACIE may incorporate software controlled elements, which are required to fulfil mandatory requirements of this European Standard (see Clause 14), but which are supplied to the manufacturer. A good example is an alphanumeric display module, but there are many possibilities including both physical modules and embedded software (e.g. operating systems). Such elements may be traded world-wide as commodity items, and detailed software documentation (and for that matter details of the hardware design) may not be available to the VACIE manufacturer. It is not the intention of this European Standard to forbid the use of appropriate technology and in such cases the detailed requirements for documentation and design of 14.2 and 14.3 may be relaxed, as long as sufficient information is provided to allow performance to be evaluated. However, it is expected that products from third parties which are designed and produced exclusively for a VACIE are fully documented and fulfil the requirements. The manufacturer has to ensure that the element is of proven reliability and is suitable for the application. Proven reliability can be assumed if the components under question are freely available on the market and there is sufficient field experience (e.g. > 1 year). The interface with the main application has to be clearly and comprehensively specified, and this documentation has to be available to the test laboratory.
C.2 14.4 deals with program monitoring. The program is the software necessary for the VACIE to carry out mandatory functions (including any declared options with requirements). The execution of the entire program has to be monitored. Monitoring can be carried out either by means of a hardware watchdog system or by another processor. The program may include software which runs in more than one processor and software in elements supplied to the manufacturer. The degree of monitoring should be sufficient to ensure that the VACIE is at least able to meet the requirements of this standard. In the case of an alphanumeric display module, it is considered to be sufficient to routinely check that data written to the module may be read back from it.
C.3 14.4.5 requires that, in the event of a failure of program execution, the VACIE shall enter a safe state. The safe state is defined by the manufacturer, but should not result in the false activation of mandatory outputs, nor give a false impression to a user that the VACIE remains operational if it is not. In practice, it may be acceptable either to stop, or automatically restart the program execution. If there is a possibility that memory may have been corrupted, the restart procedure should check the contents of this memory and if necessary, re-initialise the running data to ensure that the VACIE enters a safe operating state. Even if program execution is successfully restarted, it is important that the user is made aware of the incident. For this reason it may be advantageous for the VACIE to be capable of automatically recording details of the restart event. In any event the system fault indication has to be latched until a manual intervention.
C.4 14.5.1 requires that all executable code and data necessary to comply with this European Standard is held in memory which is capable of continuous, non-maintained, reliable operation for a period of at least 10 years. In the existing state of the art, memory with moving mechanical parts is not believed to be sufficiently reliable. For example; the use of tapes or, magnetic or optical data discs, for the storage of programs and data, therefore, is not considered suitable at the time of drafting this European Standard.
General information about voice alarm systems
D.1 General
A voice alarm system (see 3.1.22) that is connected to a fire detection and fire alarm system provides the evacuation function for that system which would have been provided by alarm sounders (item C of Figure 1 in EN 54-1:1996).
Voice alarm system configurations vary widely to suit different applications.
The most important criteria for defining the system configuration are the applicable design guidelines or code of practice and the emergency procedures for the building, including requirements for audibility and intelligibility.
D.2 Example of a simple voice alarm system
Figure D.1 is a schematic diagram of a simple fire alarm voice alarm system. In this case there is a recorded message which is activated on instruction from the CIE. In such a simple system there may be no emergency microphones or manual controls.
In the example given, the voice alarm system only broadcasts one message at a time and therefore only requires a single audio channel.
D.3 Example of a more complex voice alarm system
Figure D.2 is a schematic diagram of a more complex fire alarm voice alarm system. The system has:
Because this system can play different messages in different fire alarm voice alarm zones and the emergency microphone can also access selected zones; it requires several audio channels.
A complex system may have manual controls for activating messages on different fire alarm voice alarm zones.
D.4 Use of voice alarm for non-fire emergency purposes
A fire alarm voice alarm system may also be used for non-fire alarm purposes as follows:
— for bomb alert messages, in which case the emergency procedures will be different than for a fire alarm;
— for general public address announcements and background music.
In an alarm situation it is normal to prevent the system from being used for non-alarm purposes.
Non-alarm requirements may affect the design significantly. For instance, the sub-division of a voice alarm zone into many paging zones may add significantly to the complexity of the monitoring of the system.
NOTE 1 The VACIE and CIE may be housed in the same cabinet and share common functions (see Annex F). NOTE 2 The VACIE and the CIE may derive their power from the same power supply (item 12).
NOTE 3 The end-of-line device is an example to fulfill the requirement of this standard to monitor the loudspeaker wiring. Other solutions not using an end-of-line device are acceptable.
