Canned radio receiver ROP-21 is the final element of EXTA LIFE system that allows you to control all devices in the home or office. The output in the form of a single normally open contact makes it possible to control the low voltage circuit (e.g. 12/24 V AC / DC) and high voltage (230 V AC). ROP-21 works well for remote triggering of other devices, and the administration signals. The receiver can also be successfully used to control solenoid valves in heating systems. The current state of the device controlled by ROP-21 is shown in the mobile application through the bi-directional communication between the receiver and controller. Such a way of communication also allows the receiver and remote parameterization adding transmitters (without physical access to the receiver).Frame encoding algorithm ensures security control. ROP-off controller 21 can be operated in parallel from the system transmitters EXTA LIFE. The receiver can enter more transmitters which enables independent control of several places. The device is designed for installation in installation boxes underground and surface-mounted. Additional, configurable inputs wired enhance the functionality of the control.
