AQUA Ring is a digital passive infrared detector in oval enclosure,
designed for ceiling mounting. It is ideally suited for use in locations where
wall mounting is difficult or just impossible, for example, in rooms with fully
glazed walls or showcases. It can also be used in spacious premises, because
its design allows protection of a large area. AQUA Ring is provided with
a quad 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. Three-step
sensitivity control makes it possible to adjust the device performance to
requirements of the user and the protected premises. The detector has
a tamper switch to protect it against opening the enclosure. The device
meets the EN-50131 requirements for Grade 2.
The main task of the detector is to detect violations in the protected
area. However, it can also be used to implement the building automation
functions. When the alarm system is not armed, the detector can control turning
on the lights, opening or closing the doors, etc.
