This presentation will focus on the various types of sprinkler systems, their basic components, and functions. Additionally, common failures are discussed as well as methods for recovering from the loss. Two case studies are presented. This seminar will detail how to investigate claims related to these types of events to help determine coverage and extent of damage.
