Bosch Addressable Sounder with Flash light with Built in two Isolator
Brand : Bosch
Model: FNM-420-A-BS-RD + FNS-420-R
Country of Origin: GERMANY
Features:
- Volume of up to 92.1 dB(A)
- Maximum current consumption of less than 3.85 mA
- Up to 100 sounders per LSN loop
- Immediate synchronization
- 32 different tone types can be selected (incl. DIN tone)
The Base Sounders Indoor are used for signaling an
alarm directly at the fire location. They can be
employed either as base sounders or stand-alone
sounders.
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 92.1 dB(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.
