The LFB series bells are intended for fire alarm application only. The gong is of cast alloy metal suitable to produce loud and standard alarm bell sound. Three gong sizes are available to suit high or low noise level applications. It produces a characteristic sound with a 95 dBA @ 10Ft. for 6” bell, 83 dBA @ 10Ft. for 8” bell and 85 dBA @ 10Ft.
* Optional Backbox available for Outdoor Use.
