Top 5 Installation Mistakes to Avoid with Micro Fire Suppression Systems

Even the best fire suppression systems can underperform if they’re installed incorrectly.

At FIRESCI, we’ve worked with installers, engineers, and facility managers around the world, and we’ve seen firsthand where simple mistakes can compromise protection.

Here’s a breakdown of the top five most common fire suppression installation mistakes — and how to make sure your system is ready to perform when it matters most.

1. Improper Detection Tubing Placement

The Issue:
Detection tubing that’s routed too far from critical ignition sources — or tubing that’s loosely installed, sagging, or pinched — can delay activation or even miss a fire entirely.

The Right Way:
Route the detection tubing neatly and securely across key ignition points such as breakers, transformers, terminals, and batteries. Maintain smooth curves without sharp bends. Ensure the tubing is supported, taut, and unobstructed to allow a clean rupture exactly where heat is detected.

2. Incorrect System Pressure or Pressure Loss

The Issue:
Systems that are under-pressurized during installation, or that lose pressure due to unnoticed leaks, may not activate correctly in an emergency.

The Right Way:
Always verify the system pressure before and after installation.
Use the cylinder’s integrated pressure gauge to confirm it matches the labeled operating pressure (example: 195 psi for FK5-1-12 systems).
Perform a 24-hour pressure check to confirm system integrity after installation.

3. Using the Wrong Fittings or Connectors

The Issue:
Swapping FIRESCI-approved fittings with generic alternatives can lead to leaks, ruptures, or pressure failures under fire conditions.

The Right Way:
Only use fittings designed, rated, and pressure-tested for your specific micro suppression system.
This includes T-fittings, elbows, couplings, and end-of-line fittings that are rated for the agent and system pressure.

4. Ignoring Cabinet Ventilation and Volume

The Issue:
Protecting a heavily ventilated or oversized cabinet with an incorrectly sized system can result in the agent dissipating too quickly — leaving hot spots vulnerable.

The Right Way:
Always assess the protected volume and account for ventilation losses.
If ventilation is significant, adjustments in agent quantity or cabinet modifications may be necessary to ensure complete, effective suppression.

5. Poor Cylinder Mounting

The Issue:
Mounting cylinders loosely, at incorrect angles, or without proper support can damage system components over time and impact performance during discharge.

The Right Way:
Secure all cylinders to stable surfaces using the approved mounting brackets provided.
Cylinders should be installed vertically (valve facing upward) unless otherwise specified.
Ensure mounts are tight and that cylinders are not exposed to vibrations or mechanical stress.

Quick Installation Checklist ✅

• Detection tubing routed across ignition points

• System pressure verified before and after installation

• Only FIRESCI-approved fittings used

• Cabinet volume and ventilation properly assessed

• Cylinders securely and correctly mounted
