Honeywell Silent Knight PS-BB Pull Station Back Box

Product Description

The Honeywell Silent Knight PS-BB is a back box designed for use with compatible pull stations in fire alarm systems. It provides the required recessed mounting enclosure that allows a pull station to be installed flush against a wall surface, giving a clean, code-compliant finish. Licensed fire alarm technicians and low-voltage contractors typically install this component during new construction or system retrofits. The PS-BB is sold as a single unit and is a purpose-built accessory within the Silent Knight fire accessory product line.

The PS-BB is used in commercial and light industrial fire alarm installations where a pull station requires a dedicated back box for proper wall mounting. It is suited for use in corridor, stairwell, and exit-area applications where manual pull stations are required by code. This back box is categorized as a fire alarm accessory and is intended for use alongside a compatible pull station device rather than as a standalone alarm component.
