The SMART4 is the logical further development of the SDX-751 TEM optical thermal multisensor smoke detector. It combines 4 sensors with different criteria into one effective unit.
The CO sensor, using EC cell technology, to detect CO gases of a fire; the IR sensor, to measure ambient light conditions and flame signatures; the optical smoke sensor to detect smoke and soot particles and the thermal sensor to detect temperature change.
The integration of continuous monitoring of the 4 main elements of a fire, allows the fastest detection of a fire, while maintaining the highest immunity to disturbance variables.
The philosophy behind the development of the SMART4 was to create a detector with the highest possible immunity to disturbances in normal operation, but which is extremely sensitive to the detection of the typical criteria of a fire.
Following this development, temporary disturbances are detected and ignored for maximum reduction of false alarms.
The SMART4 contains an integrated advanced algorithmic intelligence, which dynamically adapts to the measurement results of the individual sensors or the fire characteristics. This enables continuous, real-time adaptation to changing environmental conditions.
Based on the different sensor signals, the threshold values of the sensors are dynamically controlled by the detector intelligence.
