Productoverzicht
Algemeen Informatie
The indoor sounders are used independently for signaling an alarm directly at the fire location.
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 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
Complies with
EN 54-3:2001
EN 54-17:2005
Installation/configuration notes
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.
2 | FNM-420-A Sounder Indoor
Sound pressure level specified with a tolerance of ±3 dB(A), measured at a distance of 1 m. Constant sound pressure level between 22 V and 33 V operating voltage. Default setting: tone in line with DIN 33404, part 3 Results from EN54-3 testing: lowest value at 15 V at maximum volume level, measured on the measurement axis with the highest results. All other measurements are taken 'on axis' and are not third party verified.
