Compliance Signature

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.

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.

Praesideo does not support the optional disablement condition.
