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

at 3 m distance for the indication of the supply of
power, and
•
at 0.8 m distance for other indications.
13.7.2 If flashing indications are used, both the on period

and the frequencies of flash shall not be less than
•
1 Hz for voice alarm indications, and

Compliance
All indicators of the Praesideo system can be visible at
access level 1. The installer must ensure correct
implementation of this requirement.
Manual controls of the Praesideo system at access level 1
are accessible without special procedures.
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.
Entry to access level 2 is restricted by a special procedure;
refer to clause13.6, access level 2 description for details.
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.
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.
Praesideo is compliant.
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.
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.
Disablement indication is not available in the Praesideo
system since Praesideo does not support the optional
disablement condition.
Praesideo is compliant.
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.
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.
