Bosch Security Systems B.V. IUI-PRAESIDEO_4.0 | V1.0 | 2013.01 Installation and User Instructions
5 information on the communication parameters
employed on each transmission path,
6 recommended cable parameters for each
transmission path, and
7 fuse 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.
