Praesideo 3.5 | Installation and User Instructions | EN54-16: 2008 en | 50
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.
