Two Speaker Circuits on ACC-25/50 Application Examples
5.3 Two Speaker Circuits on ACC-25/50
Dual Output Zone, Single Input Channel - tone/voice message (see Table 2.7 on page 37 for Mes-
sage Control switch settings).
This application consists of one ACC-25/50 Series with two speaker circuits which requires instal-
lation of the optional second amplifier. This configuration is suitable for small facilities requiring
no more than 50 watts of output power and a 60 second fire evacuation message.
In this application, the addressable FACP directs tone or voice messages to either of the speaker cir-
cuits via the control modules which are connected to the CMD1 and CMD2 inputs. S3 DIP
switches 1, 2 and 3 are set to OFF which configures CMD1/CMD2 to direct the Fire Message to the
Auditorium/Classroom speakers respectively. S5 DIP switch 5 is set to ON which causes CMD1
input to be activated by a contact closure and S5 DIP switch 6 is set to ON which also causes
CMD2 input to be activated by a contact closure.
The system can also be manually activated via the keypad by selecting the Auditorium and/or
Classroom Speakers zone push-button followed by the selection of the Fire Message push-button
or by using the microphone to make an announcement. Manually deactivating a speaker circuit is
accomplished by pressing the activated (illuminated) output zone push-button. Refer to the keypad
example in Figure 5.3.
