It is a very simple user friendly system. And can be installed on Wireless System. EyeT offers the option of setting up call systems for toilets for the disabled in all public areas. The system is also ideal for areas in which people with a mobility handicap or others in need can call for assistance. By pressing the emergency call button an alarm message is generated in the form of a continuous audible signal and a flashing signal light outside the toilet. The LED (relief light) integrated into the button indicates to the person needing help that her/his call has been recognized and that help is on the way. Pressing the stop pushbutton, which is preferably installed next to the WC door, acknowledges the alarm and the relief light as well as the acoustic and optical signal go out. The call system can easily be extended by further signal buttons and remote signalling if required.
