Trouble Bus
The DAA trouble bus connections are used to send general trouble messages to an FACP. The
trouble relay is used mainly as a backup in the event the monitoring panel loses communication
with the DVC over a standard or high-speed Noti-Fire-Net, or with direct-connect to a panel.
Figure C.17 illustrates wiring the Common and Normally Open out connections to an FMM-1
monitor module.
