Silent Knight sd505-6ab Addressable Detector Base 6 Inch

Product Description

The SILENT KNIGHT sd505-6ab is a 6-inch addressable detector base designed for use with compatible 505 series smoke and heat detectors in commercial fire alarm systems. The base provides the electrical connection point between the detector head and the fire alarm control panel, keeping field wiring organized and protected within the base housing. A twist-lock mounting design allows the detector to seat firmly in place, supporting reliable signal communication while enabling quick removal during routine maintenance or inspection. Installation results in a low-profile appearance suited to ceiling or wall mounting in occupied commercial spaces.

The sd505-6ab is intended for commercial fire alarm installations where addressable detection is required. Typical deployment environments include offices, schools, hospitals, apartment buildings, and other multi-zone facilities that rely on addressable fire alarm control panels for individual device identification and monitoring. The base serves as the stable mechanical and electrical interface between the wiring rough-in and the detector head, making it a standard component in any 505 series addressable detection layout.
