Types of FDAS Fire Detection & Alarm System

Addressable (FDAS) Fire Detection and Alarm System

Addressable alarm systems display the location of each initiat-ing device on the FACU and an annunciator panel if provided. This connection enables emergency respond-ers to pinpoint the specific device that has been activated. Addressable systems reduce the amount of time that it takes to respond to emergency situations. These systems also allow repair personnel to quickly locate and correct malfunctions in the system.
