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.
