6. FUNCTIONS & OPERATION OF EMERGENCY/GENERAL-PURPOSE BROADCASTS
6.1. Emergency Broadcasts
A system that integrates the FS-7000EV allows emergency broadcasts to be made automatically, through
connection to an automatic fire alarm system, or manually via the FS-7000CP unit in the main rack system.
When implementing an emergency broadcast, volume controls on the front panels of the FS-7006PA and FS-
7012PA amplifiers are bypassed to allow broadcast of the emergency message at maximum volume.
Systems equipped with an FS-7000AT can supply 24 V DC power to the 4-wire system attenuators in order to
bypass them.
Emergency broadcasts have the highest priority.
When an emergency broadcast is activated, the following occurs:
• In the emergency broadcast area: General-purpose broadcasts* are stopped to allow the emergency
broadcast to be heard.
• Other areas: If the system has been set to a 1-channel broadcast mode, general-
purpose broadcasts are stopped.
If the system has been set to a 2-channel broadcast mode, priority
broadcasts are stopped but BGM broadcasts continue.
When an emergency broadcast ends, the following occurs:
• In the BGM broadcast area:
The broadcast does not return to its original state if the system has been set to 1-channel broadcast mode.
The broadcast returns to its original state if the system has been set to 2-channel broadcast mode.
If a priority broadcast was already in progress when an emergency broadcast is activated:
• If the broadcast was from the microphone of the FS-7000CP, then it will not be resumed.
The broadcast area must be selected again when making a microphone announcement.
• If the broadcast was from the FS-7000RM, then it will return to its original state.
• If the broadcast was a telephone paging or timer-activated automatic broadcast, the broadcast will resume if
the paging operation or timer input activation still continues.
*Refer to "Types of General-Purpose Broadcasts" explained in the following section.

6.2.1. Types of General-Purpose Broadcasts
General-purpose broadcasts can be classified as follows, depending on the type of equipment, broadcast
priority, etc.
(Listed by priority)

[Timer-activated automatic broadcasts]
When the Timer Input on the rear of the FS-7000CP receives an audio signal and a control signal from a
music play component, the broadcast is made to all zones during operation of the music play component.
[Telephone paging]
When the Paging Input on the rear of the FS-7000CP receives an audio signal and a control signal from a
telephone exchange, a paging call from a telephone set is made to all zones.
