Direct & Indirect Release Electrical Cabinet Fire Suppression System with Detection Tube
Products Description
The PRI-SAFETY Electrical Cabinet Fire Suppression System is an automatic fire protection solution designed specifically for electrical panels, control cabinets, distribution boards, server racks, and other enclosed equipment spaces.
Using a heat-sensitive detection tube, the system can independently detect fire at the earliest stage and release extinguishing agent immediately and automatically, without external power or human intervention.
The system is available in two configurations:
Direct Release System – The detection tube bursts at the fire source and discharges the agent directly at the ignition point.
Indirect Release System – The tube only detects heat; extinguishing agent is released through dedicated nozzles for full-cabinet coverage.
It is a reliable, fast-acting, and cost-effective solution widely used in modern electrical and industrial automation environments.
Features & Benefits
Automatic & Fast Response: Highly sensitive detection tube reacts quickly to heat rise or open flame. Rapid activation ensures suppression at the earliest stage.
No Power Required: Entirely mechanical activation-no electricity, wiring, or electronics required.
Precise Point Detection (Direct System):
In direct release systems, the tube ruptures exactly at the fire source, maximizing suppression efficiency and minimizing agent consumption.
Flexible Installation: Detection tubing can be routed freely inside cabinets with complex layouts. Easy to retrofit on existing equipment.
Clean & Equipment-Friendly Agent: Uses clean extinguishing agents such as FK-5-1-12, FM200
Low Maintenance & Cost-Effective: Simple structure, long service life, minimal maintenance.
Lower overall cost compared to traditional centralized gas systems.
High Reliability, No False Alarms: Mechanical activation avoids false triggers caused by sensors or electronic interference.
Resistant to vibration, dust, and electromagnetic environments.
Working Principle
Direct Release System:
The detection tube is installed inside the cabinet.
When a fire occurs, heat softens the tube at the ignition point.
The tube ruptures, turning the rupture location into a discharge nozzle.
The extinguishing agent is released directly onto the fire, extinguishing it instantly.
Best for:
Small cabinets, localized fire risks, and installations requiring point-source suppression.
Indirect Release System:
The detection tube senses heat and ruptures at high temperature.
Pressure drop triggers the cylinder valve.
The extinguishing agent is discharged through metal nozzles designed for full-area coverage.
The entire cabinet interior is protected evenly.
Best for:
Larger control cabinets, densely packed equipment, and systems needing complete coverage.
