Wireless Micro-router/Gateway For Point-2-Point Wireless CO2 Control



  • Designed to relay TR9299-WiFi CO2 readings to a remote location where a 0-10VDC output is generated. Ideal for a low cost implementing of CO2 DCV with existing Economizer or RTU controls without the need for wiring.
  • Three different configuration options:

    1. Stand-alone private network Point-2-Point.

    2. Create private network with multiple units.

    3. Integrated with existing WiFi network.

  • Functionality does not require tapping into an existing WiFi network. Ideal for security conscious IT managers.
  • Can receive signals from up to 4 TR9299-WiFi transmitters and pass through the highest level.
  • Can share the signal from one TR9299-WiFi between multiple output locations.
  • Built-in webserver makes setup easy using a tablet, smartphone or PC. Status of system available at any time via Wifi interface. If connected to a network, automatic text/email messages can be generated to indicate status/alarms.
  • Fast installation. Only connections for the GW4201 are 24VDC/VAC power and CO2 output (0-10VDC).
  • Can be integrated with the AirTest GW4205 WiFi/Cellular gateway that allows connectivity to the Internet. Supports up to 20 GW4201 units.
  • May need a readily available WiFi repeater to penetrate some roof and flooring structures.
