13.8.3 Mandatory indications on an alphanumeric display
shall be legible for at least one hour following the display of
a new indication of the voice alarm condition and at least
5 minutes for fault or disablement conditions, at 0,8 m
distance, in ambient light intensities from 5 to 500 lux, at
any angle from the normal to the plane of the display up to
• 22.5º when viewed from each side, and
• 15º when viewed from above and below.
If the Praesideo system enters the voice alarm condition the
display of the network controller will automatically show the
‘Emergency’ menu. This indication stays on as long as the
system is in the voice alarm condition (i.e. until the voice
alarm condition is reset).
If the Praesideo system enters the fault warning condition
the display of the network controller will automatically show
the ‘Faults’ menu with the current number of active faults.
This indication stays on until either the rotary knob of the
network controller is used to navigate through the menu, or
the system enters the voice alarm condition. The ‘Faults’
menu will always be present in the Network Controller
menu. Individual faults are present in this ‘Faults’ menu until
they are reset or until they are overwritten by newer faults
The menu can show up to 200 individual faults after which
the oldest faults are deleted when new faults occur.
The display of the Network Controller complies with the
legibility demands of this clause.
13.9 Indication colors Praesideo is compliant.
13.9.1 The colors of the general and specific indications
from light emitting indicators shall be
a red for indications of voice alarms; The system status LED of Praesideo call stations is on
(red) when the system is in the voice alarm condition. The
installer must connect a red light emitting indicator to an
‘Emergency alarm indicator’ output contact of the
Praesideo system. The key of a call station keypad kit shall
be configured to the action ‘Zone status’. The installer must
connect a red LED to the appropriate control output
belonging to this key.
b yellow for indications of
1 fault warnings, and
2 disablements, or
The Power/Fault LED of Praesideo call stations is yellow
(on or flashing) when the system is in the fault warning
condition. The installer must connect a yellow light emitting
indicator to the ‘Fault alarm indicator’ output contact (or
another output contact configured for this function). A call
station key indicator lights up yellow when the key is
configured to the action ‘Reset fault’ or ‘Ack and reset’ and
the system enters the fault warning condition.
Disablement indication is not available in the Praesideo
system since Praesideo does not support the optional
disablement condition.
c green for the indication that the VACIE is supplied with
power.
All light emitting indicators of the Praesideo system that
indicate power supply are green.
NOTE - Where voice alarm automatic message status
indicators are provided, it may be advantageous to indicate
the difference between evacuation and alert messages. In
this case, red will be used for emergency messages and
yellow may be used for alert messages.
13.9.2 The use of different colors is not necessary for
indications on alphanumeric displays. However, if different
colors are used for different indications, the colors used
shall be as specified in 13.9.1.
The alphanumeric displays used in the Praesideo system
do not use different colors for indications.

13.10.1 Audible indicators shall be part of the VACIE. The
same device may be used for voice alarm zone activated
and fault warning indications.
The installer must connect buzzers to output contacts
configured as ‘Emergency alarm buzzer’ or ‘Fault alarm
buzzer’. The installer may decide to connect both the voice
alarm activated output contact as well as the fault warning
condition activated output contact in parallel to the same
buzzer.
13.10.2 The minimum sound pressure level, measured
under anechoic conditions at a distance of 1 m, with any
access door(s) on the VACIE closed, shall be
