S4-34760 Duct Smoke Sensor (Duct Housing)
The S4-34760 Duct Smoke Sensor is an advanced optical smoke detection system specifically designed for installation inside ventilation and air conditioning ducts. It is used to detect smoke particles traveling through air ducts, helping prevent the spread of fire and toxic smoke throughout a building.
This system works by sampling air inside the duct using a Venturi tube, which continuously draws air into the detection chamber. The sensor housing is installed externally on the duct, making it easy to access for installation and maintenance.
In case of smoke detection, the system can automatically trigger safety actions such as shutting down ventilation or air-conditioning systems. This helps control smoke movement and reduces fire damage risks in large buildings.
The S4-34760 is designed for reliable performance, easy installation, and compatibility with modern addressable fire alarm systems. It also supports multiple sampling tube lengths and includes airflow indication for proper installation verification.
