Figure 2: View of the DBS728
The sounder beacon interbase DBS728 provides an optical and acoustic alarm in
addressed fire detection systems FS720 and FC360.
The sounder beacon interbase DBS728 can be activated by any point detector via
the control panel.
If a fire alarm is triggered, the loud sound of the interbase can be clearly
recognized as a danger signal and white LEDs give a visual indication of the
danger situation.
13 tones are programmed in the interbase. Two alarm levels can be activated for
different events
(e.g., alarm and evacuation).
There are two programmable brightness levels, 'dark/low' and 'light/high'.
If a point detector is not used, the blanking plate BP720 (accessory) can be fitted
on the interbase.
