Note that when the ANN-BUS Annunciator option is enabled at the FACP, speaker circuits at the
ACC-25/50ZS or ACC-25/50ZST are automatically assigned dedicated zone numbers. These zone
numbers can then be programmed to addressable input devices which will allow the input device to
activate the programmed speaker zone.
The following table lists the zone numbers that are automatically assigned to each speaker circuit.
Note that the ACC-ZSM Zone Splitter Module installed in the ACC-25/50ZS or ACC-25/50ZST
provides 8 Style Y (Class B) speaker circuits. Additional speaker circuits can be added using the
ACC-25/50DAZS.
IMPORTANT! Messages have a priority scheme with Message 1 having the highest priority and
Message 5 having the lowest priority. For example, If an input zone activates a speaker circuit pro-
grammed to generate Message 5, that message will be generated over the selected speaker zone. If
later, another input zone activates a speaker circuit programmed to generate Message 3, Message 3
has a higher priority then Message 5 and will therefore be generated over both activated speaker
zones. The highest priority message will always be generated over all activated speaker circuits.
Programming Messages to FACP Zones
To Program one of five messages to a speaker zone, press the ENTER key at the FACP. The follow-
ing screen will be displayed:
