Silent Knight WSK-RELAY SWIFT Wireless Relay Module

Add flexible, wireless control to fire safety and building systems with the Silent Knight by Honeywell WSK-RELAY SWIFT Wireless Relay Module. This relay interface module delivers reliable, supervised switching through isolated Form-C (SPDT) contacts, enabling common fire and life-safety functions such as elevator recall, door-holder release and HVAC/fan shutdown without costly wiring runs.

Built for security and monitoring applications, the WSK-RELAY joins a resilient SWIFT smart mesh that self-heals and lets every device act as a repeater—reducing equipment and installation footprint. It integrates directly with Silent Knight 6000 Series addressable fire alarm control panels using the SWIFT gateway and the FACP SLC loop, simplifying commissioning and ongoing diagnostics. The module ships with four CR-123A lithium batteries (UL listed life ~2 years) and is rated for typical indoor environments (32°F to 120°F), making it dependable for building automation, surveillance support and fire alarm networking.
