A Distributor’s Guide: Choosing Between Direct and Indirect Fire Suppression

In high-risk environments like manufacturing plants, engine bays, and CNC machinery, having the right fire suppression system can mean the difference between fast containment and catastrophic damage. 

Fire incidents in these settings can lead to costly downtime and extensive repairs, which is why understanding the differences between direct and indirect fire suppression systems is essential for any distributor.

Understanding Direct vs. Indirect Fire Suppression Systems

Direct and indirect systems each have unique mechanisms and applications, suited to different types of high-risk areas. 

Direct Fire Suppression Systems

Direct systems are designed for targeted response, focusing on extinguishing fires at their source. In these systems, heat-sensitive detection tubing is placed near potential fire risks, to protect critical assets such as high-risk machinery components or electrical panels.

Direct systems deliver the extinguishing agent precisely where it’s needed, making them an efficient choice for smaller, confined spaces. They are especially suitable for high-risk sensitive equipment, such as, enclosed electrical equipment, where fire risks are localised and contained within a concealed space. When Clean Agents are utilised, there is no cleanup, damage or corrosion, allowing for minimal downtime.

Indirect Fire Suppression Systems

Indirect systems are designed to provide a more diverse and controlled coverage across a broader area. Nozzles are utilised to either total flood the enclosure or protected space, or target the at-risk item in a local application fashion, effectively controlling fires that may start at multiple ignition points. 

These systems are ideal for larger, complex areas where a fire could ignite in various locations, such as large engine bays, large CNC Machines, fuel stores and risks that require manual activation. 

When to Choose Direct vs. Indirect Suppression Systems

Understanding when to recommend a direct or indirect system can be challenging for distributors. 

Both systems are designed to operate independently of electrical power. Additionally, both approaches are compatible with multiple suppressant agents. Here are some guidelines to consider:

For Targeted Protection
Direct fire suppression systems are best suited for smaller, high-risk areas such as electrical cabinets or panels, where fires are likely to originate in specific components and have the advantage of a relatively sealed compartment.

For Comprehensive Coverage
Indirect systems are ideal for larger enclosures, such as engine bays, generators and dust collectors, where fires have multiple points of ignition and require larger coverage and/or multiple nozzles.

Cost and Maintenance Requirements
Direct systems tend to be more cost-effective for smaller spaces due to their precise release mechanism, whereas indirect systems provide more comprehensive coverage with slightly higher installation and agent costs.

Comparing Direct vs Indirect Fire Suppression Systems 

Choosing the Right System: What to Consider Before Deciding 

When deciding between direct and indirect fire suppression, consider the unique needs of the environment, potential ignition sources and storage space and access. Here’s how these factors influence system choice:

Size and Complexity of Protected Area
Direct systems are often more suitable for compact, confined spaces where fire risks are concentrated around specific components. Indirect systems work well in larger or open areas, providing coverage for multiple ignition points or where the source of a potential fire may vary across the protected space.

Cost-Effectiveness
Both systems are extremely cost-effective as they look to detect and suppress the fire at its earliest and smallest stage. However, the Direct system is inherently simpler and has a smaller cylinder range so will command a lower price point. It is common to see the Direct systems being used in conjunction with traditional total flood systems as they will typically activate and provide protection for a dedicated risk before the larger, more expensive systems discharge.

Environmental Responsibility
Both direct and indirect systems are compatible with multiple agents, we offer solutions that are non-conductive and leave no residue with the best chances of extinguishing the fire. For businesses aiming to align with sustainable practices, we can work with you to provide a solution that is: low ozone depletion potential (ODP) and minimal global warming potential (GWP) is a responsible choice. Like our Reacton 1230 Clean Agent. 

By evaluating these factors, distributors can confidently guide clients toward the fire suppression system that best meets their needs and provides the highest level of protection.
