Special Hazard Suppression Systems

Overview

Clean Agent Fire Suppression Systems are advanced life safety systems designed to quickly detect and suppress fires without damaging sensitive equipment or leaving residue. These systems are ideal for protecting mission-critical environments such as data centers, server rooms, telecommunications facilities, control rooms, and high-value assets where water-based suppression is not suitable.

Sophos Fire Systems provides comprehensive inspection, testing, and maintenance services for all types of clean agent fire suppression systems. Our NICET-certified technicians are experienced with all major manufacturers and clean agent types, ensuring systems operate reliably, comply with applicable NFPA standards, and are ready to perform when needed.

Inspection, Testing & Maintenance

Monthly/Quarterly Inspections

• Visual inspection of cylinders/containers, brackets, and signage
• Verify cylinder pressure/gauge readings (or weight checks where applicable)
• Inspect piping/nozzles for damage, obstructions, or unauthorized modifications
• Control panel status verification (normal condition, correct indicators)
• Inspect releasing devices and detection interfaces (smoke/heat, manual release, abort)
• Check batteries and power supply status (voltage/charging indicators)
• Trouble and supervisory signal review and resolution
• Confirm protected area integrity items (door closers, penetrations, dampers where applicable)

Annual Testing

• Functional testing of releasing control panel and associated circuits
• Test system sequence of operation (pre-discharge, alarms, time delay, and release logic)
• Test manual release and abort (in accordance with system programming and site procedures)
• Verify notification appliances and monitoring signals (local and central station where applicable)
• Inspect/verify solenoids, actuators, and releasing devices (without agent discharge)
• Test batteries under load and verify charging performance
• Inspect pressure switches and supervisory devices
• Verify interface functions (HVAC shutdown, door holders, shunt trip/ESD where required)

Common Deficiencies

• Low cylinder pressure or out-of-tolerance cylinder weight
• Missing caps, damaged cylinders, loose brackets, or inadequate seismic restraint
• Obstructed, painted, or misdirected discharge nozzles
• Improper room integrity (unsealed penetrations, door gaps, or failed dampers) impacting concentration hold time
• Trouble/supervisory conditions ignored (ground faults, open circuits, disabled points)
• Expired or missing hydrostatic test dates / required recertifications
• Incorrect programming, time delays, or disabled abort/manual release features
• Missing signage or unclear instructions at cylinder locations and control panels
