Building, fire and life safety codes often require the installation of duct smoke detectors in heating, ventilating and air conditioning (HVAC) ducts for the detection of fires in HVAC systems. Typically, these codes refer to NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems, to determine if and where they are required. NFPA 72 in turn refers to the National Fire Alarm Code for specific design, installation, and maintenance criteria for these detectors.

A duct smoke detector is a device or group of devices used to detect the presence of smoke in the airstream of ductwork sections of the HVAC air-handling systems used in public facilities. Duct smoke detection not only serves to assist in preventing the spread of toxic smoke and combustion gases, it can also be used to assist in equipment protection applications.

What differs in every building is the HVAC footprint. Until now, most duct smoke detectors have been very similar in shape and have not been flexible to accommodate varying airduct systems.

The new System Sensor InnovairFlex™ duct smoke detector line makes it possible for the first time to accommodate multiple HVAC footprints with one unit. These versatile duct smoke detectors accommodate rectangular and square configurations.

“This revolutionary design began with extensive customer research. We took our customers’ wish lists and fed that information back to our engineers,” said Andy Kuester, System Sensor director of product marketing. “It’s amazing how many upgrades we were able to make to an existing product that was already a leader in the market.”

The InnovairFlex product line offers superb false alarm immunity, a broad temperature range from -4°F to 158°F (-20°C to 70°C), and superior status and test features. All InnovairFlex products are backward compatible to existing Innovair products, including remote test accessories.

Technicians can install new sampling tubes from the front or the back without using tools. They snap into place with a positive lock to assure a solid installation. Designers also made sure that the sampling tube spaces lined up with existing models for retrofit applications.

The range of products and accessories in the InnovairFlex product line assists you in meeting any type of code requirement.
