The new range of InnovairFlex range duct detectors consist of conventional and addressable versions. The addressable version uses the Series 200 Advanced optical detector and the conventional the Series 300 optical detector. Both ranges offer class-leading false alarm rejection through a combination of advanced hardware and software engineering. The unique air management design of the sensor cover allows the units to monitor ducts with air velocities ranging from 100 to 4000 ft/min without an increased false alarm risk. Both versions can be fitted with a module to control ancillary equipment; the module is mounted in the unit, saving the cost of an additional conduit box and extra wiring.

Uniquely, the housing is made up of two interconnected sections that are hinged together, allowing them to be installed in rectangular or square configurations to suit the space available. To simplify installation, the air sampling tubes can be installed, replaced or removed from either the front or the rear of the unit with a large termination area giving plenty of room for cables.

InnovairFlex has a very wide operating temperature and humidity range, allowing the units to be installed in aggressive environments such as machine rooms, roof voids and other spaces where the temperature and humidity excursions are likely to be extreme.
