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.
