Door and window contact with solar cell, radio transmiter, in white/black/EV1.

The closing control is a wireless radio transmitter without battery. Maintenance is not necessary. The integrated solar cell allows the power supply. The closing control consists of a sensor housing and a magnet housing, which are mounted at the window frame and sash. An integrated reed contact in the sensor housing supervises the magnet and reports immediately every status change (window open, window closed). In addition a life signal is sent at least every 30 minutes.
