NO FLOW DUCT
SMOKE DETECTOR
Purpose/Application
National and local safety standards and codes recognize the ability of air duct systems to transfer smoke, toxic gases, and flame from area to area. Sometimes smoke can be of such quantity as to be a serious hazard to life safety unless blowers are shut down and dampers are actuated. The primary purpose of duct smoke detection is to prevent injury, panic, and property damage by reducing the spread (recirculation) of smoke. The detector samples air currents passing through a duct and gives dependable performance for management of smoke and combination fire smoke dampers. Duct smoke detection can also serve to protect the air conditioning system itself from fire and smoke damage.
There are several important documents that provide guidance concerning the performance, application and installation of duct detectors:
1)NFPA Standard 90A, Installation of Air Conditioning and Ventilation Systems
2)NFPA Standard 92A, Recommended Practice for Smoke Control Systems
3)NFPA Standard 72, National Fire Alarm Code
4)NFPA Standard 101, Life Safety Code
5)UL Standard 268A, Standard for Smoke Detectors for Duct Applications
6)ASHRAE Handbook and Product Directory, “Fire and Smoke Control”
7)System Sensor, Guide for Proper Use of Smoke Detectors in Duct Applications.
Duct detectors are:
NOT a substitute for an open area smoke detector NOT a substitute for early warning detection
NOT a replacement for a building’s regular fire detection system
