AQUA Plus is a digital passive infrared detector provided with a dual element PIR sensor and digital motion detection algorithm. Owing to the two-track analysis of the signal from the PIR sensor (valuable and quantitative) and the temperature compensation feature, the device is characterized by high sensitivity and interference immunity. Interchangeable Fresnel lens and three-step sensitivity control make it possible to adjust the device performance to the user requirements. The detector has a built-in tamper switch to protect it against opening the enclosure. In addition, the device PCB is provided with EOL resistors for easy installation and connection to the alarm system. AQUA Plus meets the EN-50131 requirements for Grade 2.
