Silent Knight WSK-HEAT-ROR SWIFT Wireless Heat Rate-of-Rise Detector

Protect retrofit and new-construction sites with the Silent Knight by Honeywell WSK-HEAT-ROR SWIFT Wireless Heat Rate-of-Rise Detector — designed to deliver dependable, addressable heat monitoring where traditional wiring is costly or impractical. This wireless rate-of-rise heat detector detects rapid temperature increases across open areas (UL 521 approved spacing up to 50 ft), sending secure, encrypted communications across the SWIFT mesh to your FACP for fast alarm response. Built on Silent Knight’s SK protocol and including a B501W base plus four CR123A batteries, the WSK-HEAT-ROR ships ready for quick surface-mount installation and predictable field maintenance. The mesh’s redundant child-parent paths and frequency hopping reduce interference and ensure consistent reporting to your control panel, making it an excellent choice for commercial security, fire monitoring, and multisite surveillance integrations. Ideal for schools, healthcare, warehouses, and retrofit projects where minimizing disruption is critical — add the WSK-HEAT-ROR to your system to strengthen fire detection and simplify site deployment.
