Overview

A defined scope across specialty suppression.

Lee provides support across a wide range of special hazard fire suppression systems — from inspecting and servicing existing installations to in-house design of clean agent systems.

Inspection & Service of Existing Systems

Inspect and service a broad range of installed systems so you can maintain performance, stay aligned with inspection requirements, and address deficiencies as they arise:

  • Clean agent systems
  • CO2 systems
  • Dry chemical & foam systems
  • Water mist systems
  • Releasing panels & associated controls

Design & Installation of Clean Agent Systems

Lee performs in-house design and installation for clean agent systems — including system design, coordination, installation, and ongoing service:

  • FM-200
  • Novec 1230
  • Ecaro 25

Commonly used where water isn’t appropriate — data & server rooms, electrical equipment spaces, and critical control environments.

Design

Clean agent systems, designed in-house.

Lee designs clean agent systems in-house, sized to the room they protect and coordinated with detection and releasing controls. Design includes:

  • Hazard and room evaluation
  • Agent selection: FM-200, Novec 1230, or Ecaro 25
  • Agent quantity and nozzle placement calculations
  • Detection and releasing panel coordination
  • Room integrity considerations so the agent holds

For other specialty systems, design is completed through qualified partners, with Lee handling installation and long-term support.

Design · Applications

Selected by hazard — not by building type.

Special hazard systems are typically used where water-based suppression isn’t appropriate, where equipment or assets need additional protection, or where the hazard is tied to a specific process or condition. That includes data centers and computer rooms, clean rooms, and industrial applications such as CO₂ protection for bearing housings.

Installation

Specialty systems, executed and supported.

For more complex or specialized suppression systems, Lee provides installation execution, project coordination, system integration, and ongoing inspection and service. In these cases, system design and material procurement may be completed through a specialty partner — while Lee remains responsible for installation and long-term support.

  • FOAM SYSTEMS
  • HIGH & LOW PRESSURE CO2
  • WATER MIST SYSTEMS
  • INERGEN & INERT GAS
  • DRY CHEMICAL SYSTEMS

Installation · Integration & Controls

Suppression is only part of the response.

Special hazard systems rely on more than suppression hardware. Proper integration ensures systems activate correctly and function as part of a complete life safety response. Because Lee’s fire alarm and suppression teams are both in-house, detection, releasing controls, and suppression are coordinated by one team. Lee coordinates across:

  1. Releasing panels: control of system actuation
  2. Detection systems: early, reliable initiation
  3. Fire alarm integration: a coordinated building response
  4. Shutdown sequences & control logic: safe, correct operation

Inspection

Kept effective over time.

Like all fire protection systems, special hazard systems require ongoing inspection and service to remain effective. Clean agent systems need a full inspection and test every year, agent checks every six months, and an annual review of the protected room for new openings. CO₂ systems add a monthly inspection and semiannual cylinder weighing. Lee supports the full cycle:

  • Routine inspection & testing
  • Ongoing service & maintenance
  • Recommended corrective actions
  • Identification of deficiencies
  • System condition evaluation

Already have a system but unsure of next steps?

Lee can review system condition, identify performance concerns, evaluate inspection findings, and plan upgrades or replacements.

Long-Term Support

Supported for the life of the system.

Protected spaces change: new equipment, relocated racks, new openings in walls and ceilings. Lee stays with the system after installation:

  • Service and repairs
  • Recharge coordination after a discharge
  • Adjustments when the protected space changes
  • Releasing controls and fire alarm integration support
  • Planning for upgrades or replacement

With detection, releasing controls, and suppression handled by one team, one call covers whatever changes.
