Secutron MIX-4010-DUCT 4000 Series Intelligent Photoelectric Duct Smoke Detector, Includes Head

Ensure early, dependable smoke detection inside HVAC ductwork with the Secutron MIX-4010-DUCT 4000 Series duct smoke detector. This addressable photoelectric detector includes the intelligent MIX-4010-D head, continuously measuring air obscuration and communicating directly to the FACU using the MGC MP protocol for seamless monitoring and security system integration. Engineered for low-velocity airflow, the detector uses Venturi-effect sampling tubes and offers multiple tube length options to capture smoke reliably even when duct air speeds are minimal—reducing false negatives and improving life-safety response times. Installation and maintenance are simplified by the installer-friendly one-pipe design and a clear cover for quick visual inspection, minimizing downtime and commissioning effort. Optimized to channel airflow over the sensing chamber and fit a wide range of duct widths, the unit is ideal for commercial buildings, data centers and critical infrastructure where robust fire monitoring, security and surveillance of air-handling systems are crucial.
