High-Line MA code switch 3-channel 868 Mhz bi-linked

Description The Wireless Code Switch lets you open automatic doors by entering a 4-digit PIN. It works on the 868 MHz frequency and uses secure Bi-linked technology, which confirms your command and gives updates. You can set up three personal PINs, one temporary code usable three times, and one master code for managing the system. A red LED indicates that a signal has been sent successfully. The device uses strong encryption for high security. It is splash-proof and dust-resistant, making it suitable for outdoor use. The switch works with all Marantec operators and can also be used with other systems when a Bi-linked receiver is added. It runs on two AA 1.5V batteries and is easy to install.
