a a separate light emitting indicator (the general fault
indicator), and
The Praesideo system provides a visual indication when
it is in the fault warning condition via the fault LED of the
call stations, control output contacts, key indicators of
call station keys, the fixed fault output contact of the
network controller and the front panel menu of the
network controller.
All Praesideo call stations have a specific fault indicator,
the power/fault LED, which is blinking yellow for a
system fault and steady yellow when there is a fault in
the call station or the Praesideo network is not
operational. The power/fault LED is green when there is
no fault in the system.
Control output contacts can be configured as ‘Fault
alarm indicator’. A visual indicator (e.g. a lamp) can be
connected to the output contact. The output contact is
activated when the system enters the fault warning
condition. The output contact is de-activated when the
system leaves the fault warning condition, i.e. when all
faults are reset.
Call station keypad keys can be configured to the action
‘Reset fault’ or ‘Ack and reset fault’. The key indicator of
such a key will now light up when the system enters the
fault warning condition. The key indicator is turned off
when the system leaves the fault warning condition.
Output contact 5 of the network controller is the fixed
Fault alarm indicator output. Other control outputs can be
configured for the same function. If a visual indicator is
connected to this output contact it can be used as the
general fault warning indicator.
The network controller displays the number of present
faults. This fault indication overrules the normal display
information.
b an indication for each voice alarm zone and/or an
indication for defined group(s) of zones.
The key-indicators on call station keypad kits (or regular
keypads) can be configured for ‘Zone status’, to show
that a (voice) alarm is active for a specific zone or group
of zones. A second key indicator for this ‘Zone status’
function shows whether the zone is in fault state. The
zone fault state indicator is the visual representation of
the collection of all faults that may affect the voice alarm
in that zone.
The zone fault state is also available on PC call stations,
connected to the Open Interface. Here the zone-icons on
the screen get a fault warning indication in case of a
zone fault.
More in general: all faults are visible on the front panel
menu of the Network Controller and via the Praesideo
logging application.
By configuring sensible names for the zones and
amplifier outputs contributing to these zones, fault
indications become clear and easy to understand. For
instance, a zone can have the name 'Floor_3' and output
4 of amplifier 'A6', contributing to that zone may have the
name 'Floor_3 A6_4'. A short circuit on that amplifier
output will then be shown including its name 'Floor_3
A6_4' and it will be clear that the sound on Floor_3 will
be affected.

disablement condition

alarm zone(s) associated with each manual control shall
be available without any manual action and shall not be
suppressed. This indication shall be by
