System Sensor Europe has developed new detectors to provide fire protection for the square and circular air conditioning ducts that form part of air conditioning systems.

System Sensor's InnovairFlex

The company’s new range of InnovairFlex detectors consist of either conventional and addressable versions. Both ranges have been designed with false alarm technology and geared towards use in machine rooms, roof voids and other spaces with high temperature and humidity.

A spokesman for System Sensor said: “The 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.”

The housing, made up of two interconnected sections that have been hinged together, has been designed to allow the sensors to be installed in rectangular or square configurations.

According to System Sensor, 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”.
