What makes this deal worth a look

  • Easy to Install

    The receiver is simply plugged into a power outlet. The magnetic sensor is attached to a door or window (distance between the two parts ≤ 1 cm). When the contact is triggered, the receiver emits a ringing melody accompanied by a flashing LED signal.

  • Function Settings

    The receiver has 48 different ring tones with a maximum volume of 97 dB. It also supports a silent mode, in which only an LED light bar flashes – the brightness of which can be adjusted in 6 levels.

  • Long Range

    The transmission range between the receiver and the door/window sensor is up to 180 m/600 ft. A perfect connection is guaranteed even with obstacles such as walls. The receiver has a memory function, and the original setting is retained after a power failure.

  • Switchable Contact

    Our door/window sensors have an internal toggle switch. In the “KS” position, the sensor works as a normally closed (NC) contact and triggers when opened. In the “1527” position, it works as a normally open (NO) contact and triggers when closed. This allows you to flexibly adapt the trigger method to your requirements.

  • Expandability

    The receiver has a programming function and can be linked to door contacts, motion sensors, or push-button doorbells—up to 32 devices are supported in total. In addition, it enables specific operations in which dedicated channels are assigned to individual doorbells.
