Bulk c02 system guide


If you are reading this, you are most likely aware of the many benefits of a bulk CO2 system and are either considering of have already decided to have a bulk CO2 system installed at your facility.

There are many national, state, and local codes governing a bulk CO2 system. These requirements can vary from one jurisdiction to another. If this is your first experience, or if you have had one in the past, you know it can be overwhelming.

As Arizona’s and Nevada premier leader in CO2 detection, Global Systems United has helped many clients just like you. Our unsurpassed CO2 team of experts will not only guide you through the process, but will show you where you can reduce cost along the way. Page 2 of this guide will show some of the ways we can help REDUCE your overall cost.

While there are many factors to consider, Global Systems United has provided this guide to get you started in the right direction.

Below is a list of the main items required:


Most jurisdictions require both engineered bulk CO2 drawings and CO2 detection drawings.

– The bulk CO2 drawings show the location of the bulk tank, the tank specifications, and how it correlates with the building layout. It also shows the gas tubing, tank cabinet or screening wall, and finally demonstrates the dimensions needed to protect the system installation. GSU’s engineering team can create and submit the drawings to meet the requirements of your jurisdiction.

– The CO2 detection drawing indicates the location of the CO2 detectors, the CPU, power back-up, audio/visual devices, and how it will integrate with the building fire alarm system for monitoring. The submittal also describes the sequence of operation for the different levels of CO2 gas detected. GSU’s engineering team can create and submit the drawings to meet the requirements of your jurisdiction.


Your bulk CO2 system must be monitored with a CO2 detection system. The type of detection system and the quantity of detectors depends on the location of the tank, the carbonators, and the purity of the CO2 throughout the building. GSU can review the location and equipment to provide you the most cost effective option.


Horns, strobes, and sometimes both are required to notify personal in the event a CO2 detector is activated. The placement and quantity are determined by an analysis of the equipment, the floor plan, and the entry/exit points. In some cases, if your fire alarm system has horns and strobes, we may be able to integrate the new detectors with these. GSU will help you find the most economical option.


CO2 detectors are available in 24 volt and 120 volt options. They also require back-up power in the event the primary power is lost. GSU will review the power options with you to determine the best option for your application.


The CO2 detection system will need to be monitored. If you have a monitored fire alarm system, we can most likely accomplish the monitoring by simply integrating the two systems together. GSU will review the fire alarm panel to ensure it has the available capacity to add the new CO2 detectors.


Global Systems United has many ways to drive your bottom line cost to a minimum. When we review the project with you, we will point out proven cost saving ideas to keep things as cost effective as possible. Below are a few of the primary ways we can reduce your over-all expense:


Depending on the dilution, type of gas, and the location, there are different detection options available. GSU is Arizona’s EXCLUSIVE dealer for the LOGICO2 Smart Systems and it is the only system which offers a FIVE-year factory warranty. This means we have the ability to provide you the best detection system at the lowest cost.


If this is a new building or if you will be adding a new fire alarm system, we can provide and install the fire alarm system. By doing this, our engineering group can combine the FIRE ALARM drawing, the BULK CO2 drawing, and the CO2 DETECTION SYSTEM drawing all in one package. When the drawings are created and submitted as a package, you only pay for ONE PERMIT instead of THREE.


Rather than paying a fire alarm contractor to install cabling, then paying the CO2 detection contractor to install cabling, GSU can install the cabling on both systems at the same time. In most cases, this can reduce the overall labor cost as much as 50%!


If you do not have a company already monitoring your fire alarm system, GSU also provides 24/7 monitoring. We have many monitoring options to reduce the initial system cost when you choose to use Global Systems United as your monitoring company.
