Product Overview

The WSK-WGI Silent Knight is the wireless gateway of the SWIFT® (Smart Wireless Integrated Fire Technology) system, designed to integrate wireless fire alarm devices with Silent Knight addressable fire alarm control panels. It connects directly to the SLC loop of compatible panels, allowing wireless detectors, modules, pull stations, and A/V devices to communicate seamlessly with the fire alarm system.

Using a proprietary Class A wireless mesh protocol, the WSK-WGI enables reliable, supervised communication in environments where traditional wiring is difficult, costly, visually sensitive, or restricted.
