Chapter 5: OPERATION

2. EMERGENCY BROADCASTS

5 -11

Step 3. Following this, the sensors installed on 1F

and 3F detect irregularities and the fire alarm

system transmits a control signal to the

control input. Emergency broadcast patterns

2 and 4 are also recalled in addition to pattern

3, and broadcast zones are added, and the

alert message is also broadcast to 1F and 3F,

as well.

Step 4. After the set 5-minute time interval elapses,

the message is automatically switched from

Phase 1 to Phase 2. Broadcast zones change

to the "entire zone" and the evacuation

message is broadcast to the entire area. The

evacuation announcement continues until the

Remote Microphone's reset key is pressed

or a reset signal is transmitted from the

connected fire alarm system.

Step 5. The fire alarm system transmits a reset control

signal to the control input.

The emergency mode is terminated and

the broadcast reverts to general-purpose

broadcast mode, restoring BGM output.
