D3D wireless door and window sensor mounted on a home window

Real-Time Protection

Know the second a door or window opens.

The sensor's two halves — the magnet and the transmitter — sit flush against each other while closed. Separate them, and the transmitter instantly radios your D3D alarm panel, which fires off a mobile alert or call before an intruder gets past the threshold.

Compatibility

Built for the 433MHz standard.

Designed to pair with the D3D Smart Life alarm system (model ZX-G12), this sensor also works with most third-party alarm panels that operate on the 433MHz radio frequency — check your existing system's specs before ordering to confirm the match.
