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.
