Bosch FMM-100BB-R

The Bosch FMM-100BB-R is a surface-mount red metal back box designed to provide robust, accessible mounting for Bosch FMM-100 Series fire alarm manual stations in commercial and institutional facilities. This 4.75 x 3.25 x 2.25-inch back box offers a finished appearance while accommodating single or dual-action manual pull stations with die-cast metal housing. The surface-mount configuration allows flexible installation on walls, pillars, or posts without requiring flush mounting in existing back box cavities, making it ideal for retrofit applications, temporary installations, or facilities where wall modification is not feasible. The red color provides high visibility and compliance with fire alarm identification standards.
