Lince dual technology presence detector 360° 1597

Dual technology indoor presencedetector for ceiling installation consisting of 1 PIR and 1 microwave with planar antenna at 10.525 GHz. The very thin circular structure makes it particularly suitable and effective in domestic installations. A sophisticated algorithm that simultaneously analyzes the two detection technologies, makes it suitable for installation in difficult environments, ensuring a high degree of immunity to phenomena that in other types of detectors could be a source of improper alarms.

The sequence of the pre-alarms provided by the two sensors is properly analyzed by the microprocessor avoiding that external phenomena such as air currents, heat sources and electrical disturbances give rise to unwanted alarms. Equipped with anti-masking function (by pulse counting) and warning function. The masking of the infrared sensor is detected, when the system is turned on, after five activations of the microwave in an interval of thirty seconds without the infrared sensor has made a detection; in this condition the operating logic switches from AND to OR and an alarm signal is sent. The warning function is activated if, when the system is switched off, one of the technologies has detected fifty times without the other having made any detection.

The realization with SMD components has made it possible to obtain reduced dimensions despite the complexity of the functions performed, greater reliability of the circuit and not least a high immunity to electromagnetic interference. The hemispherical lens and the microwave with planar antenna, provide coverage of 360 °. The coverage area in the widest part is about 11.4 m if installed at a height of 4 m. Complies with CEI 79-2 2nd edition '98 Level I.
