Wireless magnetic sensor

The sensor is installed on a door, window or hatch and reacts to its opening.

The sensor consists of the following parts:
- a wireless transmitter that is installed on the stationary part of the door/window.
- a magnet that is installed on the moving part of the door/window.

When the magnet and the transmitter move away from each other, the transmitter LED flashes red and sends an alarm signal to the security device. The sensor is powered by one CR1632 battery.
