The radio controller set provides a versatile solution for control of alarm systems, automatic opening gates or other devices. In addition to the relay outputs, controlled with key fobs, the receiver is equipped with additional signaling outputs. They can be used to indicate arming/disarming the alarm system, and to warn of low battery of the key fob.

Because of the superheterodyne receiver with narrowband filtering, the RXH controllers provide superior range (up to 200 m) and high interference immunity.
