Product Overview
The Dwyer CMS300-FC Carbon Monoxide Transmitter and Switch provides proportional carbon monoxide monitoring for underground parking garages, vehicle repair shops, loading areas, and mechanical rooms. Its field-selectable 4–20 mA or 2–10 V output allows connection to building automation or ventilation controllers, while the built-in SPDT relay can be used for alarm or fan control.
The electrochemical CO sensor provides a 0–300 PPM measuring range, 1 PPM resolution, and a typical 5-year lifespan. The unit covers up to 7,500 ft² (700 m²) or a 50 ft (15 m) radius. The -FC version is supplied with a factory calibration certificate.

Who This Product Is Best For
- Underground parking garages and loading areas requiring CO monitoring
- Vehicle repair shops and automotive service facilities
- Mechanical rooms requiring carbon monoxide detection
- Building ventilation systems requiring an analog CO signal
- Applications where one device needs to provide both CO measurement and relay switching
How to Specify & Commission It
- Mount the CMS300-FC within its 50 ft (15 m) coverage radius and away from direct air currents.
- Select the required 4–20 mA or 2–10 V output using the onboard jumper.
- Select the required relay alarm set point of 25, 60, or 150 PPM.
- Wire the analog output and relay contacts to the appropriate controller, ventilation fan, or alarm system.
- Perform field calibration using the zero and span potentiometers, A-507 calibration adapter, and appropriate calibration gas when required.
Frequently Asked Questions
What is the measuring range of the CMS300-FC?
The CMS300-FC measures carbon monoxide from 0 to 300 PPM with 1 PPM resolution.
What outputs are available?
The transmitter provides a jumper-selectable 4–20 mA loop-powered output or 2–10 V voltage output, along with an SPDT relay.
What relay set points are available?
The relay set point can be selected for 25, 60, or 150 PPM using the onboard jumper.
How long does the CO sensor typically last?
The electrochemical sensor has a typical lifespan of approximately 5 years, with output drift below 5% per year in air.
What does the -FC suffix indicate?
The -FC version is supplied with a factory calibration certificate. Its electrical and mechanical specifications are otherwise identical to the standard CMS300 configuration.
Where can the CMS300-FC be used?
Typical applications include underground parking garages, vehicle repair shops, mechanical rooms, loading areas, and ventilation control systems.
