Fixed Suppression Systems
Specialist fire suppression systems for high-value assets and critical environments where traditional methods are unsuitable
What We Do
Specialist fixed suppression systems protecting critical assets with appropriate suppression methods
Design & Installation
Bespoke suppression system design for server rooms, data centers, archives, and other critical environments. Full hydraulic calculations and agent concentration modeling.
- Room integrity testing and surveys
- Hydraulic calculations and agent sizing
- Professional installation and commissioning
- Integration with fire alarm and BMS
Suppression Agent Types
We supply and install various suppression systems including water mist, Novec 1230, Inergen, and CO2. Each agent selected based on application requirements and environmental considerations.
- Water mist suppression systems
- Novec 1230 (FK-5-1-12) systems
- Inergen (IG-541) inert gas systems
- CO2 systems for unmanned areas
Maintenance & Testing
Regular maintenance to BS 5306 standards ensuring system readiness. Includes cylinder weighing, pressure checks, control panel testing, and room integrity verification.
- Six-monthly and annual inspections
- Cylinder weighing and pressure testing
- Control panel and detection testing
- Room integrity testing
Refills & Upgrades
Agent refills following discharge or cylinder replacement. System upgrades to accommodate room changes or switch to more environmentally friendly agents.
- Emergency refill service
- Cylinder replacement and testing
- System extensions and modifications
- Agent conversion to eco-friendly alternatives

Legal Requirements & Compliance
Understanding your obligations for fixed suppression systems
Regulatory Reform (Fire Safety) Order 2005
Requires appropriate fire protection measures based on risk assessment. Fixed suppression may be necessary where traditional systems are unsuitable.
Assess asset value
Select appropriate system
Maintain regularly
BS 5306 & ISO 14520 Standards
British and international standards for fixed fire-extinguishing systems. Define design, installation, commissioning, and maintenance requirements.
Correct agent concentration
Leak testing and sealing
Six-monthly and annual inspections
Maintenance Requirements
BS 5306 mandates regular inspection and testing to ensure system readiness
Visual Inspection
Visual inspection of cylinders, control equipment, and detection devices. Verify system integrity and check for obvious defects.
Full System Testing
Comprehensive inspection including cylinder weighing, control panel testing, detection system verification, and room integrity checks.
Cylinder Hydrostatic Test
Cylinders must undergo hydrostatic pressure testing every 10 years to verify structural integrity and continued safe operation.
Common Fixed Suppression Issues
Problems we regularly diagnose and resolve
Room Integrity Failure
Leaks through doors, cable penetrations, or ceiling voids prevent achieving required agent concentration. System ineffective if room not properly sealed.
Solution: Integrity testing and sealing worksCylinder Pressure Loss
Gradual pressure loss due to valve leakage or temperature changes. System may not discharge correctly if pressure insufficient.
Solution: Cylinder recharge or replacementControl Panel Faults
Electronic faults, battery failures, or detection circuit issues. System may fail to activate or give false alarms.
Solution: Component testing and replacementRoom Modifications
Building alterations change room volume or layout. Original system design no longer adequate for modified space.
Solution: System recalculation and modificationHow We Work
Our specialist approach to fixed suppression system projects
Site Survey
Detailed survey of the protected space including room dimensions, ventilation, and potential leak paths. Room integrity testing if required.
System Design
Hydraulic calculations to determine agent quantity and cylinder sizing. Selection of appropriate suppression agent based on application.
Detailed Quotation
Comprehensive proposal including equipment specification, installation scope, and ongoing maintenance requirements.
Professional Installation
Installation by specialist engineers with full RAMS documentation. Integration with fire alarm and building management systems.
Commissioning & Testing
Full system commissioning including simulated discharge testing. Verification of agent concentration and system operation.
Handover & Maintenance
Complete documentation package and user training. Ongoing maintenance contracts to ensure continued system readiness.
