Bosch FNM-420-A-BS-RD Analog Addressable Base Sounder, Red, With Cover
Product Code: FNM-420-A-BS-RD
This base sounder is an acoustic warning unit integrated inside an addressable detector base. As it is supplied with a red cover, it can be commissioned as a standalone alarm point even without a detector. With a sound level of 92.1 dB(A) and consumption below 3.85 mA, up to 100 sounders can be connected per loop. Converting existing detector points into alarm points increases coverage without additional wiring.
