The FC 120 ferrite antenna is a passive element of the disoriented patient control system.
It does not require any additional power supply, it is connected to the position indicator IDT 129,
which via connection cable transmits a field
of 17Khz inside the FC 120 antenna.
The said antenna is placed on the edge of the gateway or door subject to control and has a maximum circular radius of 120cm.
In areas where the gateway to be controlled exceeds 120cm in width, it is possible to install 2 Fc120 antennas thus extending the detection coverage up to 240cm.
