Product Description
The following table shows the ANN-80 connections to the MS-9050UD.
Programming
Following installation and wiring of the 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" on page 106 in this manual for detailed programming information. Select the LCD
option for programming.
Trouble Response
If the ANN-80 is installed but the ANN-BUS is not enabled at the FACP, the 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 ANN-80 trouble.
To clear the ANN-80 trouble condition, enable the ANN-BUS and program the address
corresponding to the address set on the ANN-80 at the FACP.
