3. EMERGENCY BROADCASTS
3.1. Typical System Examples
Here, an example of sequential operation with the SX-2000 is explained.
[Sequential Operation]
Sequential operation consists of Phase 1 and Phase 2.
Sequence Phase 1 operates upon emergency system activation. When the set time interval elapses, the
broadcast is automatically switched to Phase 2.
[Setting Contents]
Both the broadcast messages and output zones are set for Phase 1 and Phase 2.
Assuming that these phases are set as follows:
Phase 1: The alert message is continuously broadcast for 5 minutes to each floor of each building.
Phase 2: The evacuation message is continuously broadcast to the entire zone.
[Alert and Evacuation Message Examples.]
Alert Message: The fire alarm system has been engaged. We are now checking the cause.
Please wait for further information.
Evacuation Message: There is a fire. Please evacuate immediately.

Step 1. Background music (BGM) is
broadcast to A-GF (Building A
ground floor) and B-GF (Building B
ground floor) when the system is in
general-purpose broadcast mode.
Step 2. The sensor installed on A-3F
detects irregularities, and the fire
alarm system transmits a control
signal to the control input.
The emergency mode is activated,
allowing the alert message to be
played through to A-3F.
