Ask a Question
  • Does the sensor need any gateway to work? And does it work with amazon alexa?

    The sensor needs to be used with the alarm host and cannot connect to alexa.

  • Does the "Magnetic Door" send a signal when open and close, or only when open?

    The Magnetic Door is two-way, it will alarm when it is opened. When the door is not closed, the host will remind you that it is not closed.
