The APMD-250 wireless detector operates as part of the ABAX 2/ABAX two-way wireless system. The device meets the EN 50131 requirements for Grade 2.

For motion detection, APMD-250 uses two types of sensors: infrared (PIR) and microwave (MW). The detector has a modern lens that ensures optimal distribution of IR beams. It can be replaced with the curtain lens (CT-CL) or long-range lens (LR-CL). An adjustable mirror is used so as to also protect the detector's creep zone. Advanced digital signal processing as well as dynamic compensation of changes in ambient temperature are applied in the device. APMD-250 supervises the motion detection system and indicates possible faults in its operation. The detector is characterized by high immunity to false alarms.

Configuration of APMD-250 and updating of its firmware are carried out remotely. Radio communication within the ABAX 2 system is encrypted using is AES encrypted.

The detector is powered by a CR123A 3 V battery, whose status is monitored in real time. The device is characterized by low energy consumption and the "ECO" option (available in ABAX 2 only) enables the device operation time to be extended up to four times without battery replacement.

The LED indicator signals violations in the test mode, thus facilitating the testing process of the detector.

The device can be mounted on an adjustable ceiling/wall bracket. The detector has tamper protection against opening and removal from the mount.
