Bosch FNM-320-FRD Conventional Recessed Siren, Red
Product Code: FNM-320-FRD
This red siren prepared for recessed installation serves as an acoustic warning device in conventional fire detection systems. Its sound transducer produces warning up to 112 dB(A) level. It can be powered by both 12 V and 24 V DC, protected against incorrect connection with reverse polarity protection. Embedding the housing within the wall prevents the device from protruding at stairways and passage points where impact risk is high.
