Application Examples

50 watts total power with automatic control via ACS link from the FACP (see Table 2.7 on page 37, 
Table 2.8 on page 40, and “ACC-ZSM Zone Splitter Module (ACC-25/50ZS & ACC-25/50ZST)” 
on page 41 for switch settings).

This application of the ACC-25/50ZS/T configures the Zone Splitter Module (ACC-ZSM) to 
divide 50 watts of audio from two Audio Amplifiers (ACC-AAM25) into four speaker circuits 
each.  The FACP uses the ACS link connected to the Zone Page Module (ACC-ZPMK) for auto-
matic activation of the speaker zones and for alarm activation.

Configuration switches are set as follows:

•

ACC-ZSM SW1 set to AAM1 & AAM2 and SW2 to Class B to place speaker circuits 1-4 on 
AAM1 and speaker circuits 5-8 on AAM2, configured for Style Y (Class B) wiring

•

ACC-ZPMK DIP switch S1 set for communication with an MS-9200UDLS, MS-9200UD 
software version 2.x (1=ON, 2=OFF, 3=ON) or MS-9600 software version 2.x or higher 
(1=ON, 2=OFF, 3=OFF)

•

ACC-25/50ZS/T main circuit board DIP switch S3 set for single zone mode, All-Call and two 
messages (1=ON, 2=OFF, 3=OFF)

The MS-9600, MS-9200UDLS, or MS-9200UD FACP can automatically activate the Fire Evacua-
tion or All Clear Message and any combination of the 8 speaker zones.  Manually deactivating a 
speaker circuit is accomplished by pressing the activated zone push-button on the ACC-ZPMK 
keypad.  Manual activation can be performed by pressing either of the Message push-button(s) and 
then selecting the Zone push-button on the ACC-ZPMK keypad.  All-Call Paging is possible by 
first pressing the All-Call push-button on the main panel keypad and then keying the microphone to 
make an announcement.
