Last week we explored when duct-detectors are required under the International Mechanical Code (IMC).
While the IMC is the most commonly-applied standard in the United States, it's not the only standard that dictates terms for duct detectors. Many international projects under NFPA 5000 or government facilities under Unified Facilities Criteria (UFC) pull in smoke detection requirements from NFPA 90A.
This week's post covers a cheatsheet for duct-detection requirements under NFPA 90A. Selfishly I've been wanting a quick go-to when covering fire alarm design, and now I'll have a copy for the two most common standards.
Around here we laminate cardstock color prints for these cheatsheets. If you'd be interested in purchasing a set of cheatsheets, let me know by commenting here. If there's enough interest I'll set up something in our store.
Thanks & have a great week!
