JLN has broad fire alarm test experience including hard-wired, and multiplex, addressable. We have tested and specified detection schemes, alarming and notification, signaling, and agent release/safeguards activation systems for industry, transmission & distribution facilities, generation facilities, schools, record storage centers, high-rises, offices, and most every other application. This has included not only fire detection and alarm, but also security monitoring, critical process instrumentation monitoring, gas and vapor detection, and related functions.

JLN inspection and testing services include:

• Smoke, Heat, Flame, and Incipient Fire Detection
• Manual Pull Station, Guard Tour Service
• Local and Distributed Fire Alarm Control Panel
• Audible/Visual/Tactile Notification Test (ADA compliance)
• Evacuation/Voice Alarm
• Gas and Leak Detection

Our team has inspected and specified test programs for dry chemical suppression systems for both fixed and mobile hazards. These systems are generally limited to high hazard, flammable liquid installations and/or various fuel delivery/storage systems.

Similar to our experience with water-based systems, JLN has tested gaseous-based suppression systems for numerous different hazards and occupancies. We understand the benefits and limitations of every type of gaseous system. We also know which systems pose concerns outside of those strictly relating to fire extinguishing effectiveness (e.g., life safety, toxicity, corrosion products deposition, ozone depletion and/or global warming potential, etc.). Given the rapid rate of change in gaseous system and associated replacement agents/technologies, we closely monitor the development and promulgation of standards as well as research into all available options.

JLN gaseous agent system test program development services include:

• Low and High Pressure Carbon Dioxide Systems
• Alternate/Clean Agent Extinguishing Systems
  (e.g., Halocarbons, Inerting Agents)
• Halon 1301 Systems
• Alternate Acceptance Testing Methodologies
• Halon Banking/Recycling Programs

Our team has tested water-based suppression systems of various types and configuration for various types of hazards. We can provide the right suppression system test for systems ranging from rack storage to light hazard office occupancies. We actively follow on-going research and development advancements in suppression technologies so that we can offer our clients state-of-the-art protection appropriate to their hazards/applications.

JLN water-based system test services include:

• Wet and Dry Sprinklers
• Preaction and Deluge sprinklers
• In-rack, ESFR, and High-density Applications
• Water Spray Systems
• Low and High Expansion Foam Systems
• Automated and Manual Monitor Nozzle/Deck Guns
• Standpipe and Hose Stations

Our team has tested stand-alone private water supply systems as well as those supported from municipal or site service water distribution systems. We understand the importance of qualifying supply capacity under both normal and adverse delivery conditions (e.g., MDC or drought conditions), ensuring reliability in the supply system, and ensuring proper operations of components and piping for your service conditions.

We are familiar with both National Fire Protection Association (NFPA) and American Water Works Association (AWWA) standards that apply to water supply and delivery systems and can provide both test plans and procedures and material specifications to meet your site conditions and water supply demands.

JLN services include:

• System commissioning (Acceptance testing)
• Pump and prime mover Testing Programs
• Underground and aboveground fire mains Flushing and Testing
• Hydrant and hydrant hose house distribution/arrangement testing inspection and maintenance.

The JLN team has extensive experience in the assessment of passive barrier systems. This includes structural steel fire proofing, fire walls and through-penetration seal systems, fire doors and fire dampers, conduit and cable tray wraps, fire stops, and smoke seals. We can assess installed configurations against baseline fire tests or design documents to ensure that the as-built configuration is in conformance with its design basis.

We can provide inspection and if required test services for fire resistive barriers in both new facility construction as well as retrofit plant expansions. We work to ensure that all required occupancy separation criteria are met while blending these features into part of the larger integrated whole building plan.
JLN services include inspection and assessment of:

• Fire Wall Location/Construction
• Egress/Exit Enclosure Construction/Separation Test
• Through-Penetration Seal Specification
• Interior Finishes
• Fire Wrap Envelope Systems
• Fire Door, Fire and Smoke Damper
