Application Example: 50-watt zone splitting, eight speaker circuits

50 watts total power with automatic control via ACS link from the FACP — see diagram below.

This application of the GWACCZ 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

with keypad (ACC-ZPMK) for automatic 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 software version 2.x (1 = ON, 2 = OFF, 3 = OFF).

• GWACCZ main circuit board DIP switch S3 set for single zone mode, All-Call and two messages

(1 = ON, 2 = OFF, 3 = OFF).

The FACP can automatically activate the Fire Evacuation Message and any combination of the eight speaker zones. For

speaker circuit manual deactivation, press the activated zone pushbutton on the ACC-ZPMK keypad. For manual activa-

tion, press either of the Message push-buttons, then select the Zone pushbutton on the ACC-ZPMK keypad. For All-Call

Paging, press the All-Call pushbutton on the main panel keypad, then key the microphone to make an announcement.
