Overview

A defined scope across fire alarm systems.

Lee Mechanical supports fire alarm system planning, installation, upgrades, and service with a focus on system performance, coordination, and long-term reliability.

Fire Alarm Systems as Part of Life Safety

Fire alarm systems do not operate in isolation. They are part of a broader life safety framework that may include:

  • Fire sprinkler systems
  • Monitoring services
  • Special hazard suppression systems
  • Inspection and testing programs

System performance depends not only on installation, but on how well these elements work together over time.

Fire Alarm System Capabilities

Lee supports a wide range of fire alarm system needs, including:

  • New system planning and installation
  • System upgrades and retrofits
  • Control panel replacement
  • Device upgrades and system expansion
  • Inspection & testing to NFPA 72
  • 24/7 fire alarm monitoring
  • Ongoing service and support

This allows customers to address both immediate needs and long-term system performance within a single service relationship.

Design

New System Design and Planning

For new installations or major system changes, proper design and planning is essential. Lee designs fire alarm systems to NFPA 72 with a focus on:

  • SYSTEM DESIGN COORDINATION
  • NOTIFICATION AND COVERAGE NEEDS
  • LONG-TERM SERVICEABILITY
  • FUTURE EXPANSION AND ADAPTABILITY
  • INTEGRATION WITH OTHER BUILDING SYSTEMS

The objective is not just a compliant design, but a system that performs reliably and remains supportable over time.

Design · Assessment

Evaluating Existing Systems and Defining Next Steps

Not every situation starts with a clear project plan. Many customers are working with existing systems and need guidance on what to do next. This may include:

  • Aging or unreliable systems
  • Recurring trouble conditions
  • Inspection deficiencies
  • Expansion or reconfiguration needs

Lee helps assess system condition and define the next step—whether that is inspection, service, upgrade planning, or replacement.

Already have a system but unsure of next steps?

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

Installation

New Fire Alarm System Installation

Lee installs complete commercial fire alarm systems, from the control panel to every detector and notification device, and works with your fire official through acceptance testing. Installation includes:

  • Fire alarm control panels and power supplies
  • Smoke, heat, and duct detection
  • Horns, strobes, and voice evacuation
  • Wiring, programming, and system integration
  • Acceptance testing and closeout documentation

Every system is turned over ready for inspection, monitoring, and long-term service.

Installation · Upgrades & Retrofits

Upgrades, Retrofits, and System Improvements

Many fire alarm systems require updates due to age, changing building conditions, or performance concerns. Common upgrade scenarios include:

  1. Aging or obsolete control equipment
  2. Recurring service issues
  3. Building renovations or expansions
  4. Increased notification or coverage requirements
  5. Desire for improved reliability and support

Lee helps evaluate existing systems and determine the most practical path forward—whether that involves targeted upgrades or broader system improvements.

Installation · Applications

Supporting More Complex System Applications

Fire alarm systems can vary widely in scale and complexity. Lee supports a range of applications, including:

Facilities requiring coordinated life safety systems

Factory 1

Multi-level and larger buildings

Shield 3

Systems with voice evacuation

Server Rack 1

Integrated system environments

The focus is on delivering solutions that match system demands while maintaining clarity, reliability, and serviceability.

Inspection

Fire Alarm Inspection & Testing

Recurring inspection and testing keeps your system ready and your building compliant. Service scope may include:

  • RECURRING FIRE ALARM INSPECTIONS
  • FUNCTIONAL TESTING
  • DEVICE AND NOTIFICATION VERIFICATION
  • CONTROL EQUIPMENT REVIEW
  • DOCUMENTATION OF FINDINGS
  • DEFICIENCY IDENTIFICATION AND RECOMMENDATIONS

Lee inspects and tests fire alarm systems to NFPA 72, which sets a schedule for each component. Most devices are tested every year, while some, such as sprinkler flow and tamper switches and backup batteries, are checked more often, and your local fire official can require additional testing.

Inspection · Follow-Up

Deficiencies, Follow-Up, and Ongoing Support

Inspections often lead to additional actions, including:

Server Rack 1

Corrective work

Factory 1

Ongoing maintenance

Shield 3

System Repairs

Zap 1

Upgrade planning

Equipment replacement

This is a normal and valuable part of maintaining life safety systems. A strong inspection program helps shift from reactive fixes to a more proactive service model.

Monitoring

24/7 Fire Alarm Monitoring

Lee monitors fire alarm systems around the clock and connects every signal to the right response. Monitoring covers your fire alarm system on its own, whether or not Lee services your sprinklers.

  • 24/7 signal monitoring
  • Event response and communication
  • Online access to system activity and reports
  • Connected to inspection and service

Monitoring works best as part of a complete fire alarm program — not a standalone service.

What happens after an alarm event?

You’ll know how the event was communicated, what action is needed, how follow-up service is handled, and who to call. Every event leads to a clear next step.

Monitoring · Multiple Locations

Monitoring Across Systems and Locations

Monitoring requirements can vary depending on system complexity and the number of locations involved. Support may include:

Server Rack 1

Coordinating monitoring across multiple systems

Factory 1

Providing visibility across multiple locations

Shield 3

Organizing system activity and records in one place

This helps create a more consistent and manageable approach to fire alarm oversight.
