The sounder interbase DBS721 provides an acoustic alarm in addressed fire
detection systems FS720 and FC360.
The sounder interbase DBS721 can be activated by any point detector via the
control panel.
The loud sound of the interbase can be clearly recognized as a danger signal in
the event of a fire alarm.
11 tones are programmed in the interbase.
Two alarm levels can be activated for different events
(e.g., alarm and evacuation).
If a point detector is not used, the blanking plate BP720 (accessory) can be fitted
on the interbase.
