Sentra | Funk Tür Fenterkontakt für die QT1 & QT2

The Sentra Wireless Door/Window Contact is a reliable sensor for securing windows and doors. It reliably detects opening and closing and immediately sends a signal to the alarm center in the event of unauthorized access. This enables early alerting in the event of a break-in.

The compact design allows for discreet installation on virtually any door or window frame. Thanks to the generous distance of up to 2.1 cm between the sensor and the magnet, effective monitoring is guaranteed even with wider frames or double-leaf elements.

Installation is incredibly simple: The sensor can be either glued or screwed on. An integrated tamper switch ensures that any tampering attempts are detected and reported. Power is supplied by a long-life button cell (CR2032), whose status is automatically monitored. This ensures the contact's reliable operation at all times.

The sensor is fully compatible with the Sentra QT1 and QT2 alarm control panels.
