What is a duct smoke detector and how does it work?

In an event of a fire emergency, duct systems of the building with recirculating air handling systems, can become a dangerous route to spread smoke, harmful gasses, and fire throughout the whole building, posing a major threat to life of occupants and the property.

Duct smoke detectors are designed to be installed inside the building heating, ventilation, and air conditioning (HVAC) ductwork to monitor the air recirculating inside the building duct system and provide early detection and warning, and shutdown the HVAC system to prevent recirculation of smoke and toxic gasses.

Duct Sampling Tube

Duct smoke detectors sampling the air moving in the duct system for smoke or fumes presence. They are equipped with a sampling metal tubes located inside the duct that constantly takes moving air from inside the duct and push it into a photoelectric sensing chamber and circulates the air back to the duct using a separate exhaust tube, resulting in constant sampling of air. During this constant sampling process, if smoke is detected, the device will trigger alarms using an auxiliary replay and shutdown the HVAC system to prevent recirculation of smoke and toxic gasses.

Duct detectors are designed to only work within the HVAC systems. They are not a replacement for fire detection or early warning equipment in open parts of buildings.

When are you required to install a duct smoke detector and where they must be placed?

The Ontario Building Code | Smoke Detectors in Recirculating Air Handling Systems Except for a recirculating air system serving not more than one dwelling unit, where a fire alarm system is required to be installed, every recirculating air handling system shall be designed to prevent the circulation of smoke upon a signal from a duct-type smoke detector were such system supplies more than one suite on the same floor or serves more than 1 storey.

The Ontario Building Code | Return-Air System In a house containing two dwelling units, return-air from one dwelling unit may be recirculated to the other dwelling unit, provided a duct-type smoke detector is installed in the supply or return air duct system serving the entire house which would turn off the fuel supply and electrical power to the heating system upon activation of such detector.

When you are required to install duct smoke detectors and where to place them, it is determined by the governing codes in your area.

The best answer is to always consult the local authorities to know whether you need to install duct type smoke detectors in the HVAC system of your building and where they need to be placed.
