Wireless PIR motion detector with pet immunity up to 20 kg The APD-200 Pet 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. It is provided with a quad pyroelement, advanced detection algorithm and dynamic temperature compensation, which ensure effective motion detection. APD-200 Pet supervises the motion detection system: if the system is malfunctioning, the detector will report an alarm. The device comes with the PET function, so the movement of pets (up to 20 kg) does not trigger an alarm.
