Duct Detector

Duct Detector

A duct detector is a critical fire safety device designed to detect smoke particles present in HVAC air ducts. It continuously monitors airflow and triggers an alarm when smoke is detected, helping prevent the spread of fire and smoke through ventilation systems. Duct detectors are widely used in commercial buildings, hospitals, malls, offices, data centers, and industrial facilities to ensure early warning and quick response. Designed for reliability and compliance with fire safety standards, duct detectors integrate seamlessly with fire alarm panels and building management systems for enhanced protection and safety.

Duct detectors play a vital role in modern fire detection systems by identifying smoke at an early stage within air handling units and ductwork. By shutting down HVAC systems during fire events, they help contain smoke spread and protect occupants and property. These detectors are engineered for high sensitivity, durability, and ease of installation across various duct sizes. Suitable for both new and retrofit projects, duct detectors are essential for meeting fire safety regulations in commercial and industrial buildings. Our duct detectors ensure accurate detection, long service life, and dependable performance.
