The U1-HS is a modern one-channel superheterodyne remote control set, designed as a continuation of the UMB100HS model. This set includes two single-button key fob transmitters (UMB100HT) and a compact, high-sensitivity superhet receiver (U1HR). It is ideal for wireless control of alarm systems, access control, and other automation applications, offering advanced security with dynamic KEELOQ® code encryption.
