Engineered Life Safety Systems (ELSS)

Engineered life safety systems (ELSS) or Fire Safety Evaluation Systems (FSES) are alternate life safety concepts which are required to be developed by a registered professional engineer experienced in fire and life safety system design. An ELSS or FSES are allowed by code to be provided in lieu of installing complete fire sprinkler systems in existing residential high-rise buildings in the state of Florida. While we always recommend the installation of a complete fire sprinkler system in high-rise buildings whenever possible, we understand that an engineered life safety system is often a preferable option for owners who want to reduce the cost of compliance with Florida’s high-rise retrofit law before the mandated deadline of 2024. All ELSS or FSES alternatives must also be approved by the AHJ. Neptune has developed ELSS/FSES systems for multiple residential high-rise condominiums throughout the state of Florida using the FSES method.

Fire Safety Evaluation System (FSES)

FSES systems are developed using a prescriptive scoring methodology and require a detailed evaluation of the existing building construction, hazards present within the building, and fire protection systems installed among other variables. Additionally, these systems may include any or all of the following:

  • Partial automatic sprinkler protection
  • Smoke detection systems
  • Smoke control systems
  • Compartmentation
  • Other approved systems
