Is my ”store-bought” detector enough protection?
There are two types of fire to which household fire warning equipment must respond. One is a rapidly developing, high-heat fire. The other is a slow, smoldering fire. -NFPA 72-2010. “The public believes that by buying a common smoke detector off the shelf, that before their house was filled with smoke, that the detector would sound and give them a warning. I think they believe that. That is not what will happen. That is absolutely not what will happen.”

 (Exact quote from Dr. Don Russell, PhD in electrical engineering, Associate Vice Chancellor of Texas A&M University, One of the world’s leading experts on smoke detectors.) (As seen on Canadian TV – W5 “Silent Alarms” #859-31-1143)
