Opening indicator - Reed switch

The Roto E-Tec Control MVS opening indicator (Reed switch) is an additional window protection connected to the alarm system or monitoring.

The operation principle of the system is very simple. The sensors with magnets are located in the groove of the sash, integrating it directly with the fitting. This way a magnetic field is created to "supervise" the window. When the window is closed, the field is continuous, but with open window, incorrectly closed or pried from the outside, the magnetic field is interrupted. Information is sent to the control device of the automatic system or to the integrated alarm system.

It is a great addition to mechanical anti-burglary protection installed in the windows.
