This Radio Frequency Kit allows the door to be opened remotely through an RF remote control. At the door, a receiver is required that can be located both indoors (ideal for shops and garages) and outdoors. The remote has an exclusive code per user that offers maximum security and reaches a distance of up to 100 meters using the 868Mhz frequency band. And thanks to its advanced APS (Approaching System) transmission system, the remote control can be activated even when it is out of range of the receiver. The signal will be transmitted repeatedly for 15 seconds as the user approaches the door and until the moment it is opened. The kit includes RF receiver ref. 5250 up to 500 codes, feeder ref. 4802 and 3 KeySingle Mini controls ref. 5259.
