The FDS229 alarm sounder with supplementary optical indication provides an
acoustic alarm in an addressed FS20/FS720 fire detection system. It also features
a optical display.
The loud sound of the alarm sounder can be clearly heard as a danger signal when
a fire alarm sounds. The LEDs on the additional optical display also light up.
Eleven tones are programmed in the alarm sounder. Two tones can be activated
for different events (e.g. alarm and evacuation). A set flashing sequence is
preprogrammed in the optical signal transmitter.
The alarm sounder with supplementary optical indication is available with optical
displays in various colors:
FDS229-R with transparent red hood
FDS229-A with transparent orange hood
