detector capable of sensing smoke in air velocities from 100 to 4,000 feet per

minute (0.5 to 20.32 m/sec). This Innovair features Low-Flow technology

enabling duct smoke detection throughout a broad range of airflow environ-

ments. Many difficult to solve HVAC applications occur in low airflow duct

applications where reliable smoke detection is critical. Innovair with Low-Flow

technology can detect smoke at air speed velocities of 100 feet per minute or

greater, while continuing the same reliable performance to 4,000 feet per minute.

The Innovair family is designed for simplified installation and easy maintenance.

The modular construction allows for easy cleaning and uncomplicated field

replacement of the UL recognized power and sensor boards.

DUCT SMOKE DETECTORS ARE:

NOT a substitute for an open area smoke detector,

NOT a substitute for early warning detection, and

NOT a replacement for a building’s regular fire detection system.

Refer to NFPA 72 and 90A for additional duct smoke detector application
