SILENT KNIGHT WSK-Relay

Product Overview

The Silent Knight WSK-RELAY is an intelligent, addressable wireless relay module designed to allow fire alarm control panels (FACPs) to control external devices through code-commanded contact switching. The module provides an isolated Form C relay (SPDT) and is ideal for controlling functions such as elevator recall, door holders, fan shutdown, and activation of remote power supplies.

Operating as part of the SWIFT® wireless system, the WSK-RELAY communicates securely with the FACP through a Class A wireless mesh network via a SWIFT gateway. This wireless architecture makes it an excellent solution for installations where traditional wiring is impractical, costly, visually intrusive, or hazardous.

The panel-controlled LED provides clear visual indication of module status, and the device integrates seamlessly with both wired and wireless Silent Knight systems for maximum design flexibility.
