The ML-210E is a mini-style wireless magnetic contact transmitter that monitors door and window status and sends an instant alarm to the connected control panel when the magnetic stripe and transmitter separate by more than 2.5cm. It operates at 433MHz and is compatible with all Defendo control panels, but does not work with older ML-7664 and ML-300 versions.

The detector can convert a wired contact signal to wireless, functioning as a transmitter for existing wired sensors. It automatically reports operating status to the control panel at 30 seconds, 2 minutes, and 6 minutes after first power-up or reset, then every two hours thereafter. A terminal for connecting an external wired contact is included.
