Fire, life safety: Multi-criteria detectors

April 5, 2023

Multi-criteria detectors, which combine multiple detection technologies, have become more common in the fire detector market. Multi-sensor detectors use a combination of more than one type of sensor — smoke, heat or carbon monoxide — to detect the presence of a fire. Fire detection systems are specified for the safety of the building’s occupants in the event of a fire. They may also be specified to address property protection and continuity of operations goals.

Codes and standards, including those developed by the International Code Council and the National Fire Protection Association, provide design and installation provisions for fire detection systems in the event of a fire or other emergency event.

Learning objectives:

  • Explore the challenges and solutions of designing with multi-criteria detectors.
  • Understand why fire detection systems are selected and what is driving the installation.
  • Apply fire detection system requirements to meet the objectives of the building’s fire and life safety system.
  • Review examples of multi-criteria detectors, with various fire scenarios.
