Early fire detection is critical in data center environments, where even a minor event can threaten uptime and high-value equipment. We layout and service fire alarm and early detection systems that help identify developing fire conditions before they escalate into major operational disruptions.

Systems may include:

• Smoke detection systems

• Heat detection systems

• Air sampling detection technologies

• Fire alarm monitoring

• Emergency notification systems

These systems help facility operators respond quickly to potential fire events and system abnormalities.

Clean agent fire protection systems are commonly installed in:

• Server rooms

• Data centers

• Network operation centers (NOCs)

• Telecommunications rooms

• Electrical control rooms

• Mission-critical equipment spaces

These systems discharge gaseous extinguishing agents designed to:

• Quickly suppress fire at its early stage

• Protect sensitive electronic equipment

• Minimize cleanup and downtime

• Maintain business continuity

Because the agent leaves no residue, systems can return to service faster compared to traditional water-based suppression methods.

Pre-action fire sprinkler systems are commonly installed in:

• Data centers

• Server rooms

• Telecommunications facilities

• Network operations centers (NOCs)

• Critical equipment areas

Pre-action systems use a two-stage activation process designed to verify fire conditions before water is discharged:

• A fire detection system (smoke, heat, or flame) activates

• The pre-action valve opens, allowing water into the piping

• Individual sprinkler heads must then activate from heat before water is released

This dual-action approach ensures water is discharged only during a confirmed fire event, minimizing the risk of false activation and damage.

Pre-action systems provide several advantages for mission-critical environments:

• Reduced Risk of Accidental Discharge – Water is not present in the piping until a fire event is confirmed

• Protection of Sensitive Equipment – Limits water exposure to affected areas only

• Targeted Fire Suppression – Only activated sprinkler heads discharge water

• Improved Business Continuity – Helps minimize downtime and operational disruption

Because of their controlled response, pre-action systems are widely considered a preferred fire protection solution for water-sensitive environments such as data centers and telecommunications facilities.

Ongoing inspection, testing, and maintenance (ITM) are essential for ensuring data center fire protection systems remain fully operational, code-compliant, and prepared to respond. Proper ITM practices help helps facility owners and operators maintain system reliability, document compliance, and reduce the risk of unexpected failures in mission-critical environments.

Our inspection and testing services are designed to verify system functionality and identify deficiencies before they impact operations. Services include:

• Fire alarm system testing (per NFPA 72)

• Sprinkler system inspections (per NFPA 25)

• Pre-action system testing and valve operation verification

• Clean agent system inspections (per NFPA 2001)

• Detection system verification (smoke, heat, or aspirating systems)

• Deficiency reporting and corrective action recommendations

Comprehensive ITM programs provide several advantages for mission-critical facilities:

• Code Compliance – Maintains adherence to NFPA standards and AHJ requirements

• System Reliability – Ensures systems are ready for immediate operation

• Risk Reduction – Identifies potential failures before they occur

• Documentation & Reporting – Supports audits, insurance, and regulatory review

• Business Continuity – Minimizes the risk of unexpected downtime

Data center power infrastructure may include:

• UPS (Uninterruptible Power Supply) battery systems

• Lithium-ion battery installations

• Battery Energy Storage Systems (BESS)

Each of these systems introduces unique fire hazards that require a comprehensive fire protection strategy, including detection, suppression, ventilation, and emergency response coordination.

Fire risks associated with lithium-ion batteries—particularly thermal runaway and fire propagation—require specialized design considerations. Key fire protection components include:

• Early fire detection systems (e.g. smoke detection, off-gas detection

• Fire suppression systems (e.g. clean agent, water-based systems, or hybrid solutions)

• Ventilation and exhaust systems to manage gases and heat release

• Separation and spacing requirements to limit fire spread

• Emergency response planning with local fire authorities

These measures are essential for mitigating hazards associated with data center battery rooms and Battery Energy Storage Systems (BESS).

Data center fire protection systems, server room fire suppression systems, fire alarm systems, clean agent systems, and pre-action sprinkler systems may be designed, installed, inspected, tested, and maintained in accordance with several nationally recognized NFPA standards, including:

• NFPA 75 – Standard for the Fire Protection of Information Technology Equipment, commonly used for data centers, computer rooms, and IT equipment spaces

• NFPA 76 – Standard for the Fire Protection of Telecommunications Facilities, commonly applied to telecom rooms, network facilities, and communications infrastructure

• NFPA 72 – National Fire Alarm and Signaling Code for fire alarm design, detection, monitoring, notification, and emergency signaling

• NFPA 13 – Standard for the Installation of Sprinkler Systems, including automatic sprinkler and pre-action sprinkler system design considerations

• NFPA 25 – Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, including sprinkler system ITM programs

• NFPA 2001 – Standard on Clean Agent Fire Extinguishing Systems for clean agent fire suppression in server rooms, data halls, and mission-critical equipment areas

• NFPA 855 – Standard for the Installation of Stationary Energy Storage Systems, where UPS battery systems, lithium-ion battery systems, or battery energy storage systems are present

Together, these NFPA standards help guide code-compliant data center fire protection layout, fire alarm planning, clean agent fire suppression, pre-action sprinkler protection, battery energy storage system protection, and ongoing inspection, testing, and maintenance for mission-critical facilities.

In addition to NFPA standards, data center fire protection systems must also comply with the International Building Code (IBC) and International Fire Code (IFC) as adopted by state and local jurisdictions. These codes establish critical requirements for data centers, server rooms, UPS rooms, and battery energy storage systems (BESS) areas, addressing key fire protection and life-safety considerations.

Applicable provisions may include:

• Fire-resistance-rated construction for generator, UPS, and electrical rooms

• Occupancy classifications and separation requirements for mixed-use facilities

• Hazardous materials compliance, including diesel fuel and stored energy systems

• Lithium-ion battery fire protection and ventilation requirements for BESS installations

• Emergency responder access and fire department access provisions

• Fire department connections (FDCs) and water supply requirements

• Automatic sprinkler systems and fire alarm system requirements

• Means of egress and overall life-safety provisions

Compliance with IBC and IFC requirements—along with local amendments and Authority Having Jurisdiction (AHJ) interpretations—is essential to ensure that data center and power-generation facilities meet regulatory expectations, protect life safety, and maintain operational continuity in mission-critical environments.

A fire event in a data center or server room can have immediate and far-reaching consequences, including:

• Equipment damage to critical IT and electrical infrastructure

• Data loss impacting business operations and client services

• Operational downtime resulting in service outages

• Business interruption affecting revenue and customer trust

• Regulatory and compliance consequences

• Significant financial impact due to recovery, replacement, and lost productivity

An effective fire protection strategy is essential to safeguarding both physical assets and digital infrastructure in modern data center environments.

Data center fire protection systems must comply with applicable local building and fire code requirements and are subject to review and approval by the Authority Having Jurisdiction (AHJ). The AHJ may include local fire marshals, building officials, or other regulatory authorities responsible for enforcing fire and life-safety codes and approving system layout, installation, and operation.

In addition to AHJ oversight, many data center owners and operators must also meet fire protection requirements established by insurance carriers, risk-management organizations, and property insurers. These requirements often extend beyond minimum code compliance and are focused on property protection, business continuity, and risk mitigation. In certain facilities, organizations such as FM Global (Factory Mutual) may establish additional fire protection criteria that directly influence:

• System layout and performance requirements.

• Fire detection and suppression strategies.

• Inspection, testing, and maintenance (ITM) programs.

• Fire-resistance-rated construction and firestopping.

• Overall risk reduction and loss prevention strategies.

Because code requirements, insurance standards, and facility-specific risks can vary significantly by project, each data center must be evaluated based on a comprehensive set of criteria, including:

• Applicable NFPA standards (e.g., NFPA 13, 72, 75, 110)

• Adopted IBC and IFC codes, including local amendments

• Insurance and property protection requirements

• AHJ interpretations, approvals, and inspection requirements

A coordinated approach that aligns code compliance, AHJ approval, and insurance-driven risk management is essential to delivering reliable, compliant, and resilient fire protection systems for data centers and other mission-critical facilities.
