Edwards Signaling SD-GSK SuperDuct Series Cover Gasket Kit

Designed for tight ductwork and retrofit applications, the Edwards Signaling SD-GSK SuperDuct cover gasket kit delivers dependable smoke detection where space and reliability matter most. This SuperDuct accessory pairs with SD series duct smoke detectors to provide a secure, low-profile installation with a depth under 2" — ideal for constrained plenum spaces and commercial HVAC systems. The kit features a PCB-mounted photoelectric sensor with on-board intelligence that improves sensitivity and response time, while patented differential sensing provides environmental compensation to minimize false alarms in dusty or variable-temperature environments. For security and facilities teams, the SD-GSK supports continuous monitoring and integrates seamlessly into fire and building management systems, helping maintain occupant safety and compliance. Built for professional installers and systems integrators, the gasket kit reduces install time, enhances sealing performance, and keeps duct smoke detection reliable over time. Upgrade your duct smoke detection setup with the Edwards SD-GSK for improved surveillance, security monitoring, and simplified maintenance — order now or specify it for your next HVAC smoke detection project.
