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.
