MB Series Bells 439D-6AWC 10AWC
Edwards MB Series Motor Driven Bells are specially designed for fire alarm applications. The gongs are made from select alloy steel chosen to give the loud, resonant tones necessary in fire alarm and life safety systems. Two sizes of gongs are available to help overcome different ambient noise levels. Edwards MB bells are the “under-dome” type and use heavy duty mechanisms. The bell’s base and gong are finished with a durable “fire red” baking enamel.
