Description / Abstract:
Foreword
Proper Use of Smoke Detectors in Duct Applications
The purpose of this guide is to provide much needed information concerning the proper use of smoke detectors in duct applications. Duct mounted smoke detectors are designed to provide a specific type of protection that cannot be duplicated by any other type of system. However, there has been a tendency to misapply these devices—attempting to use them as a substitute for an early warning smoke detection system. This fact, coupled with new methods of detecting smoke in ducts, has prompted the writing of this industry guide.
