Predicting the Fire Source Location by Using the Pipe Hole Network in Aspirating Smoke Detection System

The aspirating smoke detector (ASD) is one of the most critical pieces equipment for detecting in a protected area when fire occurs. It has more advantages than conventional because it can be used extreme conditions, such as cold storage facilities or hot aisle containment areas. ASD uses fan to draw air from into pipe network system via holes. sucked transported sensing chamber detect smoke. If obscuration greater setpoint, will sound an alarm so that people realize there fire. For this reason, investigating effect hole on critical. In study, Pipe Hole Network Program was developed consider flow parameter. A numerical study based program and experimental performed. results showed had same trend study. further location source was, lower was. addition, correlation between parameter distance also derived. could predict detection system.
