USC9210 Duct Smoke Detector

Protect your building’s ventilation network and maintain reliable life-safety standards with the USC9210 Duct Smoke Detector. Designed for the early detection of smoke within HVAC and ventilation systems, this advanced unit utilizes reliable photoelectric technology to continuously sense air sampled through a tube extended directly into the ductwork. When sufficient smoke concentration is detected, it instantly initiates an alarm signal to shut down ventilation fans and auxiliary equipment, preventing toxic smoke and fire gases from circulating into protected areas while stopping the spread of fire through ducts.

Engineered for seamless integration and enhanced system reliability, the detector features comprehensive alarm, supervisory, and auxiliary relay contacts to interface effortlessly with fire control panels and HVAC equipment. It incorporates advanced self-diagnosis technology to actively monitor for power supply abnormalities, communication failures, and cover dislocations, signaling any issues via flashing LEDs to ensure maximum uptime. Supporting a 2-bus input for direct access to fire bus systems, the unit accommodates sampling tubes available in various lengths—recommended to span the entire width of the duct—for optimal and comprehensive airflow monitoring.
