    Key features
    Triaxial accelerometerIt works next to the reed switch and tells a 40 mm movement from a tilt of up to 25°.
    Shock detectionIt sets the shock threshold at three levels: high, normal and low.
    Temperature measurementIt shows the range from –15 °C to +65 °C indoors with ±1 °C accuracy.
    Long battery lifeA single CR123A battery lasts 3 years on the NO input when triggered twice a day.
    Stable communicationFrequency hopping and two-way communication hold the link up to 1000 m in open space.
    Jamming detectionIt spots jamming attempts and encrypts the communication with AES128.
