Fire WAN Troubles Reference

This section lists and explains the possible fault conditions of the Fire WAN network.
Trouble messages appear on the Desigo CC station in the Event List.

• Control Panel Not Responding
  The fire alarm panel attached is not communicating and has dropped its modem carrier signal. This is a normal trouble when a panel has been powered down.
  This trouble will also correspond with a Carrier Fail LED on a HUB-4 port and a Not Responding fault on Desigo CC .
• Class X Failure
  The fire alarm panel is still communicating, but the HUB-4 has noticed an open or break failure in one of the two pairs used for Class X.
  The Open/Short LED on the HUB-4 will light with this trouble.
• Ground Fault
  The HUB-4 is indicating a ground on a port for the wiring between the HUB-4 in the remote fire panel and itself.
  The Gnd Fault LED on the HUB-4 will light with this trouble.
• Internal Modem Failure
  The HUB-4 is indicating a failure or a missing Modem Block on one of its ports.
