Product Overview
The Dwyer Series GSTC-N-D-FC Nitrogen Dioxide Transmitter is designed for monitoring nitrogen dioxide (NO₂) in ducted ventilation systems serving mechanical rooms, underground parking garages, loading docks, and other areas requiring diesel engine exhaust monitoring.
The GSTC-N-D-FC is the nitrogen dioxide version in a duct-mount configuration and communicates over RS-485 using BACnet MS/TP or Modbus® RTU protocols. This enables integration with building management systems and ventilation controllers.
The transmitter uses an industrial-grade, field-replaceable sensor. Field calibration can be performed using the A-449 remote LCD service display. When the sensor reaches the end of its service life, the service display indicates that replacement is required.
The GSTC-N-D-FC includes a factory calibration certificate. For applications that do not require factory calibration documentation, the standard GSTC-N-D configuration is available without the certificate.

How to Specify & Commission It
- Select a suitable duct installation location for the GSTC-N-D-FC and confirm that nitrogen dioxide (NO₂) is the required gas being monitored.
- Install the transmitter in the ventilation duct according to the manufacturer's installation requirements.
- Connect the power supply and 2-wire RS-485 communication wiring.
- Configure the required BACnet MS/TP or Modbus RTU communication settings, including the appropriate protocol and address.
- Verify communication and readings with the building management or ventilation control system.
- Perform field calibration using the A-449 remote LCD service display as required.
- Monitor the sensor status and replace the field-replaceable sensor when the service display indicates that replacement is required.
Frequently Asked Questions
What gas does the GSTC-N-D-FC detect?
The GSTC-N-D-FC is designed to detect nitrogen dioxide (NO₂), which is associated with diesel engine exhaust.
How does the GSTC-N-D-FC connect to a building management system?
It communicates over a 2-wire RS-485 connection using BACnet MS/TP or Modbus® RTU protocols.
Is the GSTC-N-D-FC a wall-mount or duct-mount model?
The GSTC-N-D-FC is a duct-mount model designed for in-duct gas monitoring.
Does the GSTC-N-D-FC have a built-in LCD display?
No. The GSTC-N-D-FC does not have an integral LCD display. The A-449 remote LCD service display can be used for setup, calibration, and service functions.
Can the sensor be replaced in the field?
Yes. The transmitter uses an industrial-grade field-replaceable sensor.
How is the sensor calibrated?
Field calibration can be performed using the A-449 remote LCD service display.
What does the -FC suffix mean?
The -FC version is supplied with a factory calibration certificate. The standard GSTC-N-D configuration does not include the factory calibration certificate.
Where can the GSTC-N-D-FC be used?
Typical applications include underground parking garage ventilation systems, loading dock ventilation, mechanical rooms, and other ducted ventilation applications requiring nitrogen dioxide monitoring and BMS integration.
