Remote CO2 Storage Safety 3 Alarm (RAD-0102-6)

The Remote Carbon Dioxide (CO2) Storage Safety Alarm is designed to protect individuals who tend to be in close proximity to stored carbon dioxide. This fixed gas safety monitor measures CO2 levels and detects leaks, protecting facilities from overexposure.

These types of alarms are vital in restaurants, wineries, breweries, beverage dispensing areas, dry ice storage, laboratories, cultivation facilities, or anywhere more than 100 lbs. of CO2 is stored or produced. 


  • 3 relays automatically control fans to ventilate spaces (default: 5,000 ppm TWA, 5,000 ppm, and 3% CO2)
  • 88 dB audible and visual alarms
  • Programmed to meet fire code compliance for all states
    • Meets EH40, AS5034, and UK Health and Safety Act
    • Meets OSHA and NIOSH TWA standards
    • Meets NFPA, IFC, and NBIC requirements
  • More flexible - extend remote up to 300 feet from the main unit
  • 4-20 mA output to allow for remote display of values
  • UL listed for compliance

The CO2 Storage Safety Alarm is easy to install and use. The use simply needs to mount both units on the wall (all cables and hardware included), plug the monitoring unit into a standard wall outlet, and the alarms are ready to protect your customers and employees.

The CM-1027 add-on kit comes with cables and two extension strobe lights.


CM-1027 - Dual Strobe Add-On Kit: 

Install a flashing strobe on both the Sensor Unit and the Remote Display Unit to enhance visual alarms, particularly effective in high-noise environments. Some local fire codes also require this.

CM-0126-5, 6 - Strobe Tower Add-On Kit: The Strobe Tower provides a visual indicator of which of the three alarms were triggered and offers a louder alarm for enhanced alerting capabilities.

CM-1029 - Industrial Strobe Siren: The industrial strobe siren is specifically engineered to offer an additional flashing indicator of a potential gas leak in indoor areas where compressed gases are being used or stored.

RAD-0104 - Additional Remote Display: The Sensor display unit includes one remote display, which can be positioned up to 300 ft. away using a Cat5 or greater Ethernet cable (28 ft. included in the box). Additional remote displays can be purchased separately, and up to two can be daisy-chained as long as the total run is less than 300 ft.

SV-1029 Solenoid Safety Shut-Off Valve: The remote display unit is designed to be compatible with any of CO2Meter's remote storage safety alarms and can be directly wired to the SV-1028 24/DC safety shut-off valve.

RAD-0102-6-OUT - Outdoor Enclosure: Designed to be utilized with any of CO2Meter's remote storage safety alarms, this unit can be directly installed outdoors near aggressive environments where the enclosure protects against dust, debris, and splashdown.

Calibration Gas: Due to MDOT regulations, calibration gases must be sourced and shipped from a certified gas supplier.
