Bosch FNM-420-A-WH Analog Addressable Indoor Sounder, White
Product Code: FNM-420-A-WH
Connected to the addressable LSN loop, this sounder is established as an independent alarm point in indoor spaces. With its white enclosure, it is unobtrusive on suspended ceilings and open office walls; it produces sound pressure up to 101.3 dB(A). Selection is available from 32 tones including DIN tone; sounders synchronize without delay. Its ability to support up to 100 devices per loop limits the need for additional loop cards in high-rise buildings.
