A total-coverage smoke detector system. Note: 1. The above applies to ALL BUILDINGS 2. The above matches 2001-CBC Section 713.10  NO CHANGE

Smoke Control Required Locations 2007-CBC - UL Damper Requirements Smoke Control Required Locations 2001-CBC 404.3.3 – Covered Malls 403.4 – High-Rise Buildings (B & R-1) 402.2 – Atria 405.3.3.1 – Stages & Platforms 2007-CBC 402.9 – Covered Malls 403.13 – High-Rise Buildings 404.4 – Atriums 405.5 – Underground Buildings 408.8 – Windowless Buildings (I-3) 410.3.7.2 – Stage & Platforms 1025.6.2.1 – Assembly (Means of Egress)

2007-CBC - UL Damper Requirements Summary 2007-CBC  Big Changes CAUTION  CSFM vs. NON-CSFM Regulated Buildings CSFM Bldg  Similar to 2001-CBC NON-CSFM  Big Difference New Format  Barrier Driven + Detail + Trade-Offs 350°F Single Temp Closure  Simple + Cost + Safety
