Esmi Ultima Networking Troubleshooting

Warning

Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices.

 

Note: Always completely power OFF the panel whenever inserting or removing hardware in the panel.

Issue

Not able to see the network panels status, trouble messages, events, cause and effects etc.

Product Line

ESMI Fire Detection.

Environment

  • FFSULH1009.

Cause

Networking issues can significantly impact the performance and reliability of the Esmi Ultima system. This article provides troubleshooting steps to resolve common networking problems.

Resolution

The following network-related troubles can occur on the Esmi Ultima Fire Alarm Control Panel. See the detailed descriptions below for explanations on each trouble message.

 

Trouble Message Description
Network Communications Trouble

This event indicates there is no communication between this panel and its neighbor. This could be caused by a configuration error (such as using the wrong baud rate), a wiring error, or damage to the wires connecting the panel to its neighbor. If this trouble occurs on one link on the panel, then the panel is still in communication with other panels on the network. If this trouble occurs on both links on the panel, then the panel is no longer in communication with other panels on the network.

Note: make sure remove the 0 ohm resistance from the network card.

Unexpected Network Node This event indicates a panel has been detected on the network that is not in the configuration. This is a configuration error and should never occur once the network has been properly configured.
Network Card Missing This event indicates that the panel is configured for networking, but there is no network card installed, or it is installed incorrectly. This trouble may also occur if the network card processor fails.
Connection Error This event indicates that the panel has failed to get a meaningful result for the link impedance measurement. This may occur if stray leakage current enters the link wiring from elsewhere, or if there is a component failure or missing jumper on the network card. This event may also be shown when the network is disconnected or when the NET OUT + wire is disconnected.
Network Panel Missing This event indicates that another panel is configured but has not been found on the network. This may occur if the missing panel is switched off or disconnected from the network. This fault will also occur if there is no communication between a panel and either of its neighbors on both links. In this case, the panel will show multiple instances of this trouble; one for each other panel on the network.
Network Node Double Addressed This event indicates that more than one panel on the network has the same node number. This is a configuration error and should never occur once the network has been properly configured.
Full Short Circuit Trouble This event indicates that a short circuit has been detected by the link impedance measurement. This indicates a wiring error, or damage to the wires connecting the panel to its neighbor.
Full Open Circuit Trouble This event indicates that an open circuit has been detected by the link impedance measurement. This indicates a wiring error, or damage to the wires connecting the panel to its neighbor. The following two troubles are optional and are not included in the default firmware build.
Partial Short Circuit Trouble This event indicates that the link impedance measurement has detected an impedance below the normally expected range.
Partial Open Circuit Trouble This event indicates that the link impedance measurement has detected an impedance above the normally expected range.
