Bosch Security Systems B.V. IUI-PRAESIDEO_4.0 | V1.0 | 2013.01 Installation and User Instructions
a all mandatory indications shall be visible at access
level 1 without prior manual intervention (e.g. the
need to open a door);
All indicators of the Praesideo system can be visible at
access level 1. The installer must ensure correct
implementation of this requirement.
b manual controls at access level 1 shall be accessible
without special procedures;
Manual controls of the Praesideo system at access level
1 are accessible without special procedures.
c indications and manual controls that are mandatory
at access level 1 shall also be accessible at access
level 2;
All Praesideo indications (LEDs, equipment connected to
output contacts, front panel display) and manual controls
(input contacts, call station keys, front panel menus) that
are accessible at access level 1 are also accessible at
access level 2.
d entry to access level 2 shall be restricted by a special
procedure;
Entry to access level 2 is restricted by a special
procedure; refer to clause13.6, access level 2
description for details.
e entry to access level 3 shall be restricted by a special
procedure, differing from that for access level 2;
Entry to access level 3 is restricted by a special
procedure, see clause13.6, access level 3 description for
details. Correct configuration and installation (physical
access control) will ensure that the special procedure
differs from that of access level 2. The system
administrator shall define users of type ‘user’ for access
level 2 and users of type ‘installer’ for access level 3. The
installer shall ensure that the physical access procedure
differs from that of the physical access procedure of
access level 2.
f the entry to access level 4 shall be restricted by
special means which are not part of the VACIE.
Entry to access level 4 is restricted by means of having
to use the File Transfer Application (FTA), see
clause13.6, access level 4 description for details. This
FTA is only used for access level 4 functions and is
therefore not part of the daily operation/configuration of
the Praesideo system.
NOTE - Further access levels are permitted provided that
they are distinct from the access levels described in this
standard.
13.7 Indications by means of light-emitting
indicators
Praesideo is compliant.
13.7.1 Mandatory indications from light emitting
indicators shall be visible in an ambient light intensity up
to 500 lux, at any angle up to 22.5° from a line through
the indicator perpendicular to its mounting surface
• at 3 m distance for the general indications of
functional condition,
• at 3 m distance for the indication of the supply of
power, and
• at 0.8 m distance for other indications.
All of the light emitting indicators of the Praesideo
system fulfill this requirement. When external light
emitting indicators are installed, such as LEDs
connected to a call station kit or call station keypad kit, or
light emitting indicators connected to output contacts, the
installer shall use indicators that fulfill this requirement.
13.7.2 If flashing indications are used, both the on
period and the off period shall be greater than or equal to
0.25 s, and the frequencies of flash shall not be less than
• 1 Hz for voice alarm indications, and
• 0.2 Hz for fault indications.
The voice alarm indication does not flash; it is steady on
both call stations and on output contacts.
The fault indication on a call station flashes with a
frequency of 2 Hz (on and off period of 0.25 s) when
there is a fault in the system or is steady on when there
is a fault in the call station itself. The fault indication on
output contacts is always steady on.
13.7.3 If the same light emitting indicators are used for
the indication of specific faults and disablements, fault
indications shall be flashing and disablement indications
shall be steady.
Disablement indication is not available in the Praesideo
system since Praesideo does not support the optional
disablement condition.
13.8 Indications on alphanumeric displays Praesideo is compliant.
13.8.1 If an alphanumeric display consists of elements
or segments, the failure of one of these shall not affect
the interpretation of the displayed information.
Praesideo system elements that have an alphanumeric
display all have a dot matrix LCD. If a single dot of such
a display fails the interpretation of the displayed
information is not affected.
13.8.2 If an alphanumeric display is used to display
mandatory indications, it shall be clear and
unambiguous.
The display of the network controller is used to display
mandatory indications. Indication of the voice alarm
condition is by means of the text ‘Emergency’ and the
name of the key that activated the voice alarm condition.
Indication of the fault warning condition is by means of
the text ‘Faults’ and an indication of the number of active
faults in the system. Individual faults with details are
shown in a menu structure.
