5 information on the communication parameters
employed on each transmission path,
6 recommended cable parameters for each
transmission path, and
7fuse ratings;
c specified means to limit the consequences of fault (see
13.5.2);
The IUI describes the following means to limit the
consequences of fault:
• Switchover to spare (standby) amplifiers
• Audio/control input supervision
• Backup power supply
• Redundant network cabling
• Loudspeaker line supervision
• The ability of the emergency call station to make a ‘fail
safe’ call in case of a network controller defect
• A/B group wiring of loudspeakers
• The ability of the multi channel interface to bypass
routing in case of a fatal fault in the MCI
d configuring and commissioning instructions; Configuring and commissioning instructions are included in
the IUI.
e operating instructions; Operating instructions are included in the IUI.
f maintenance information. Maintenance information of the Praesideo system are
included in the IUI.
13.2.2 The manufacturer shall prepare design
documentation that shall be submitted to the testing
authority together with the VACIE. This documentation shall
include drawings, parts lists, block diagrams, circuit
diagrams and a functional description to such an extent that
compliance with this European Standard may be checked
and that a general assessment of the mechanical and
electrical design is made possible.
All of the mentioned design documentation is available as
TPD for inspection by testing authorities.
13.3 Mechanical design requirements Praesideo is compliant.
13.3.1 The cabinet of the VACIE shall be of robust
construction consistent with the method of installation
recommended in the documentation. It shall meet at least
classification IP30 of EN 60529:1991+A1:2000.
The Praesideo call station product range, network splitter
and fiber interfaces comply with this requirement. The
installer must implement this requirement for 19”-units, by
means of using a correct 19”- frame, meeting at least
classification IP30 of EN 60529:1991+A1:2000. The EN
54-16 certification of Praesideo includes the 19"-rack. A
rack must be used from the list of approved racks.
13.3.2 All interconnections and settings inside the cabinet
shall be accessible at level 3.
The installer must ensure that the physical access to the
Praesideo system is restricted to access level 3, then
accessibility to all interconnections and settings inside the
cabinet (e.g. interconnections between the system
elements) is restricted to this access level.
13.3.3 The VACIE may be housed in more than one
cabinet. If the documentation shows that the cabinets may
be installed in locations distributed within the protected
premises, then all of the mandatory manual controls and
indicators shall be on one cabinet or on cabinets declared
to be only suitable for mounting adjacent to each other.
The IUI shows that the Praesideo cabinets may be installed
in locations distributed within the premises. One dedicated
Praesideo call station with call station keypad(s) or call
station kit with call station keypad kit(s) can then be used
for all of the mandatory controls and indicators. The installer
shall take care of proper installation in order to fulfill this
requirement.
13.3.4 All mandatory manual controls and light emitting
indicators shall be clearly labeled to indicate their purpose.
The labels shall be legible at 0.8 m distance in an ambient
light intensity from 100 lux to 500 lux.
The Praesideo call station keypad has a paper slot next to
each of its programmable keys. The installer must provide
proper labels that fit into these paper slots and implement
this requirement. Note that if the call station keypad kit is
used, the installer must provide custom-made call station
keypads, including the labels. A regular font with with
characters of 3 mm height offers sufficient readability in
case of high contrast between text color and background.
Lower contrast color selections will require bigger
characters.
13.3.5 The terminations for transmission paths and the
fuses shall be clearly labeled.
All terminations for transmission paths are clearly labeled
on all of the Praesideo system elements (near the relevant
connectors).
The mains fuse for each Praesideo system element that has
a mains connector is labeled on the rear plate of the
element.
Internal fuses have a parts code indication on the Printed
Circuit Board on which they are mounted. These fuses may
only be replaced by qualified service personnel having
access to the service documentation.
