32 different tone types can be selected (incl. DINtone)
The indoor sounders are used independently for signaling an alarm directly at the fire location.
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 101dB(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.
Certifications and approvals
The device is intended for indoor use.
The current consumption depends on the tone type selected and is maximum 4.05 mA.
The maximum number of devices on each loop depends on the cable diameter and the total current of the loop. Use the Bosch Planning Software for reliable loop planning.
This device cannot be used with the FPA-5000 type A panel controller.
