XNET Fire Network Operating Troubleshooting

This section contains troubleshooting information for XNET fire control panels (FireFinder XLS/MXL, Desigo Fire Safety Modular, and Cerberus Pro Modular).

Handle Event Problems in Operating Mode

Problem	Situation	Do the following...
Cannot silence events from Desigo CC stations. In the Event List, the silence command icon is missing. You cannot silence events from the panel PMI either.	The silence inhibit has been configured on the panel and is currently active. The silence command is only allowed after a predefined delay.	Wait for the delay configured in the fire panel tool.
All control commands have no effects.	Network connection is down: all object properties show #COM state and object symbols in graphics display a yellow grid.	Get the network connection re-established.

Cannot silence the active sound on a fire panel from the Desigo CC Event List. No event displays that can provide the silence command.	On the fire panel, the sound was generated by a condition that did not create an event. The silence command is only available from System Manager.	In System Browser, select the fire panel. In Extended Operation, select Silence. To create e specific event for unsilenced fire panels, see Configuring Unsilenced Panel Event.
Cannot silence events from Desigo CC stations. The silence command has no effect. Instead, you can silence events from the panel PMI.	When both MNS and Fire events are pending, the silence commands must be performed in order, according to the event priority in Event List.	Silence events one after the other in the order they appear in Event List OR Silence events from the panel PMI
Cannot reset fire events after an out-of-queue event occurs.	As on the PMIs in the field, out-of-queue events do not appear in the Desigo CC Event List, and, if not acknowledged, prevent older events from being reset. Note that the queue capacity is 150 events for the 9-queue setting (9Q) and 300 events for the 4-queue setting (4Q).	From the affected panel node, use the global Acknowledge command of the Panel Unacknowledged property in Extended Operation. After acknowledging the panel, you can reset the individual events as necessary.
Missing events on management station. Event List misalignment with fire panels.	In the Zeus configuration, with the Proprietary NFPA System Type setting, the Self Restoring options are not supported and may result in event misalignments.	Check the Zeus setting in Desigo Fire Safety Modular System Limits and Compatibility.

After an error during the network configuration, for example when saving an NCC station object or importing the NET configuration, you cannot treat and remove events concerning that XNET.	Due to the problem in modifying the internal configuration, Desigo CC is no longer aligned with the XNET configuration and false events may occur.	In Engineering mode, you can force a configuration alignment by creating an NCC station on the affected XNET. Refer to the engineering troubleshooting.
The `Event List Incomplete` status event displays for an XNET driver.	An event overflow occurred due to an avalanche of messages to the XNET driver. Based on the event sorting criteria, some less important events do not appear in the Event List on the screen. Note that all events are always logged in the History database and, if a printer is installed, included in the Journaling printout. See also XNET Fire Events.	Handle the pending alarm conditions and fully process all events (Acknowledged, Reset, and Close). The Event List will then align again with the fire control panels. To prevent event overflows, a configuration adjustment may be possible. Refer to the engineering troubleshooting.
