Data centers’ intricate design: Fire and life safety

Data centers are important structures that hold vital information for businesses, schools, public agencies, and private individuals. Fire suppression systems must be carefully designed.

CSE: What unique fire suppression systems have you specified in data centers?

Chadwick: Our most common data center design includes dual-interlock preaction fire suppression, however, in some areas we have specified a mist fire suppression system to minimize or eliminate potential water damage to expensive infrastructure elements.

Hogge: We have seen clients trending back toward more traditional solutions, opting for a double-interlock, preaction system using a nitrogen charge. Many jurisdictions require a sprinkler with an unlimited discharge, in theory, so at a minimum that cost must be invested. Using early-warning smoke detection to proactively react to an event before a fire alarm, coupled with the double-interlock scheme involving a smoke detector and sprinkler head melt, can give the client a reasonable confidence there will not be an accidental water discharge in the space.
