The compact IP55-rated enclosure has a separate battery compartment, allowing for quick replacement of the CR123A power cell without accessing the electronics.

The device uses a reed switch with an activation distance of 7–15 mm and a mechanical life of over 1,000,000 activations. The sensor also has a built-in temperature sensor, an input for connecting an external sensor, and an output for an LED indicator for arming/disarming. Power is supplied by one CR123A battery, with a service life of up to 5 years. The radio module operates in the 868–868.6 MHz range (EU/Ukraine) or 916.5–917 MHz (Australia) with two-way encrypted communication, power up to 20 mW, and a range of up to 4800 m in open areas.

The sensor supports over-the-air (OTA) firmware updates and has tamper protection. The operating temperature range is from −20 to +50 °C, with permissible humidity up to 95%. The model is available in several housing colors: white, black, dark brown.
