Honeywell Silent Knight PS-WPB Weatherproof Back Box

Product Description

The HONEYWELL SILENT KNIGHT PS-WPB is a weatherproof back box designed to house and protect pull station devices in environments exposed to moisture, dust, or other outdoor conditions. It serves as a protective enclosure that mounts behind a compatible pull station, shielding the device and its wiring connections from the elements. Fire alarm technicians and low-voltage contractors install this accessory as part of a complete pull station assembly where code or site conditions require outdoor or weatherproof-rated mounting.

The PS-WPB is suited for installation in locations where standard indoor pull station mounting is not appropriate, such as covered exterior egress points, parking structures, loading docks, and similar semi-exposed or outdoor areas. It is sold as a single unit and is categorized within the pull station accessories product family.
