WHAT LEE SUPPORTS
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.

INSTALLATION SUPPORT
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.

SYSTEM 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. Lee coordinates across:
- Releasing panels: control of system actuation
- Detection systems: early, reliable initiation
- Fire alarm integration: a coordinated building response
- Shutdown sequences & control logic: safe, correct operation
WHERE THESE SYSTEMS ARE APPLIED
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.
