Notifier FSD-751RPL Intelligent Photoelectric Duct Smoke Detector

Notifier Innovair FSD-751RPL Intelligent Photoelectric Duct Smoke Detector is a duct-mounted smoke detection device that uses a photoelectric sensor to identify smoke in HVAC ductwork. The FSD-751RPL designation identifies the model within the Notifier Innovair family, signaling a solution designed for installation in air ducts as part of a building’s fire alarm or life-safety system. Designed for duct environments, it provides early smoke detection by sampling air within the duct path, enabling prompt notification to the fire alarm system when smoke is present. This configuration helps protect ventilation networks and supports rapid response in commercial and institutional settings where ducted smoke monitoring is required. The product name itself communicates its purpose: an intelligent, photoelectric duct detector built to monitor duct airflow for smoke particles as part of integrated safety infrastructure.
