What type of detectors are required for installation in air distribution systems?

Smoke detectors are required for installation in air distribution systems primarily due to their role in enhancing fire safety. These detectors are designed to identify smoke particles in the air, which is a key early indicator of a fire. In air distribution systems, smoke detectors help ensure that smoke is detected quickly and efficiently, allowing for timely alerts and responses to potential fire hazards.

The integration of smoke detectors in these systems is crucial because air ducts can spread smoke throughout a building. Therefore, having smoke detectors installed at strategic locations within the air distribution network provides an essential layer of fire safety, helping to protect occupants and property. This requirement aligns with safety standards and building codes that mandate the use of smoke detection in areas where fire risks are present, making it a vital component of mechanical code compliance.
