Functions
The device allows to select 32 types of alarm and
evacuation tones (including DIN tone 33404, part 3)
for different requirements.
You can adjust the sound pressure by five levels
according to the operational environment. Depending
on the tone type and volume set, the sound pressure
varies between 65 dB(A) and 101.3dB(A).
Sounders of the same LSN loop and with the same
tone type provide immediate synchronization. The
device maintains LSN loop functions in the event of
wire interruption or short-circuit thanks to two
integrated isolators.
Change of the device settings can be done in the
FSP-5000-RPS programming software.
