Many of today’s HVAC systems are designed for airflow below the 500 feet per minute required for traditional duct mounted, sampling- tube type duct smoke detectors. Variable Air Volume (VAV) systems are designed for increased energy efficiency and occupant comfort, but may produce air flows well below 500 feet per minute at the VAV fire/smoke damper. Egress passages in occupied buildings are now required by code to provide conditioned air through a fire/smoke damper controlled by a smoke detector. Airflow rates at these fire/smoke dampers are also well below 500 feet per minute. Until now, the only approved solution for applications below 500 feet per minute is to install expensive pendant mounted, in-duct type detectors. The custom installed solutions are costly to install and difficult to clean and maintain.

The System Sensor Innovair Flex is a 4-wire photoelectric air duct smoke 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 that enables duct smoke detection through- out a broad range of airflow environments. Many difficult to solve HVAC applications occur in low air flow 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 two available form C relay contacts provide reli- able performance for the management of fans, blowers and air conditioning systems. These HVAC devices can be configured to prevent the spread of toxic smoke and fire gases through a protected area.

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. The patented interconnectability feature allows multiple Innovairs to communicate with each other. In the event smoke is detected, the Innovair will signal the remaining interconnected detectors to initiate their relays for smoke control. WARNING: Duct smoke detectors have specific limitations.

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 direction system.

The P2W “SpectrAlert” is a wall mount, white cased, two-wire strobe/horn with selectable strobe settings of 15, 30, 75, 95, 110, & 115 cd.
