The APD-200 detector is designed for operation as part of the ABAX 2/ABAX two-way wireless system. It meets the EN 50131 requirements for Grade 2. Effective motion detection is achieved thanks to the double pyro-element, digital detection algorithm and dynamic compensation of temperature in protected premises. APD-200 has a state-of-the-art lens with unique beam distribution. It can be replaced with the curtain lens (CT-CL) or long-range lens (LR-CL).
