Wireless relay unit (new)



Designed for manual control of actuators by the user through a mobile application


  • one three-contact power relay 250 V, 5 A;
  • ability to connect external wired sensors, the wire length shall be not more than 1,5 m;
  • registration in the Security Hub controller after installing the battery using Setup Wizard in the mobile application.;
  • battery size CR123 included;
  • battery life up to 1.5 years;
  • ability to connect an external 12 V power supply (backup power supply);
  • automatic switching from the battery to the external power supply when the latter is connected, when it is disconnected - back to the battery;
  • supply voltage control.


Works as part of the Security Hub GSM alarm system to protect an apartment (house) and serves for remote control of any executive devices. For example, turning on the heater at the country house in advance so that there is a comfortable temperature in the room when you arrive

Operating principle

Upon user's command from the mobile application, the relay unit receives the command from the Security Hub controller over the radio channel and turns on or off (depending on the command) the built-in power relay. Relay status is displayed in the user's mobile application.

Installation and setup

  • fastening with wall plugs (self-tapping screws);
  • it is installed close to an executive device;
  • executive device wires are connected to the relay terminals.
