Bosch FNS-420-R Red Analog Addressed Sounder Base Strobe
Product Code: FNS-420-R
The FNS-420-R, when mounted on a sounder base in analog addressed systems, adds a visual warning layer to the siren. Since it uses LED technology, consumption is low and it flashes at 1 Hz synchronous rate; power supply is between 15-33 V DC. Its red body is in the IP42 class and operates in the -20 to 60 °C range. Since it requires no additional cables or separate power source, it can be quickly added to existing addressed lines.
