The Silent Knight PS-BB is a back box for Silent Knight die-cast metal manual pull stations. It provides the wall enclosure that the pull-station front mounts onto.
First, the PS-BB pairs with the Silent Knight PS-SATK single-action and PS-DATK dual-action pull stations. Therefore, installers complete a pull-station assembly by combining the front (PS-SATK or PS-DATK) with the matching PS-BB back box.
In addition, the PS-BB simplifies surface mounting where flush installation is not possible. As a result, retrofits on solid walls or thick masonry can use the back box rather than cutting in a flush opening. Furthermore, this is a standard Honeywell Silent Knight accessory, distributed through Honeywell Building Solutions and major fire-alarm parts suppliers.
Silent Knight PS-BB Compatibility
- PS-SATK — Silent Knight single-action die-cast pull station
- PS-DATK — Silent Knight dual-action die-cast pull station
Notes Before Ordering
The PS-BB is the back box only. However, the pull-station front (PS-SATK or PS-DATK) must be ordered separately. Therefore, confirm whether the existing wall has a flush opening or needs surface-mount hardware. In addition, the LSC product title also references “SGB-32S” — that part name belongs to a Sigcom back box and does not match the Silent Knight PS-BB. Order by the verified PS-BB part number to avoid a wrong-product shipment.
