Transmitter


Last update: June 20th, 2026.

Tramsmitter is a module for integrating a third-party wired device into the Roombanker system.
Transmitter allows you to connect the detectors, keypad, panic button, or any other device with the NC / NO contact type to Roombanker. Transmitter links to the gateway via the RBF protocol, once transmitter receives a signal from the third-party device, it will send this message to gateway, gateway will arrange the next action.
Tramsmitter can output a 3.3 V / 30 mA power to the third-party device.
Tramsmitter can output a NC / NO signal to the third-party device to achieve a certain function.

2. Features​

Remote setting and testing​

Setting and testing from RB Link App

Advanced features​

  • Power up enrolling When device is powered up, it will automatically start paring to the hub nearby

  • Find me When enabled, the device starts flashing green, which can help identify the sensor from numerous devices.

  • Signal strength detection When enabled, senor starts flashing green/orange/red showing the wirelesssignal strength between the hub at current installation site.

  • Low battery notification

Indicators​

  • Alarm: Flashing Red
  • Find me: Flashing Green
  • Signal strength:

    Flashing Green: signal strength is strong, and is recommended to install devicehere
    Flashing orange: signal strength is medium and device can be installed here
    Flashing Red : signal strength is bad or no signal, and device can not be installedhere
