Installation Optional Module Installation
7. After all connections are made, remove extra wire from inside of annunciator by dressing it neatly through wire channel, with any
excess wire pushed back through hole into electrical box
The following table shows the N-ANN-80 connections to the NFW-50X.
Programming
Following installation and wiring of the N-ANN-80 LCD annunciator to the FACP, the annunciator must be added to the system via
FACP programming. Refer to the programming section titled “ANN-BUS Setup” on page 86 in this manual for detailed programming
information. Select the LCD option for programming.
Trouble Response
If the N-ANN-80 is installed but the ANN-BUS is not enabled at the FACP, the N-ANN-80 will indicate a trouble condition by NOT
turning on its AC Power indicator. The LCD will also display Key Bus Trouble and the piezo will sound approximately once every 10
seconds. Note that the FACP will provide no indication of an N-ANN-80 trouble.
To clear the N-ANN-80 trouble condition, enable the ANN-BUS and program the address corresponding to the address set on the N-
ANN-80 at the FACP.
