Effectiveness Analysis of Unwanted Fire Alarm Using Carbon Monoxide Sensors

Abstract

A carbon monoxide sensor was applied with smoke detectors, which trigger unwanted fire alarms, to improve detection reliability. Standardized fire and unwanted fire tests according to UL 268 and scenario-based tests for unwanted fire alarms were performed to analyze the detection effectiveness in fire and unwanted fire situations. Studies on improving unwanted fire alarms using carbon monoxide sensors have been conducted in various fields. However, additional concentration measurements using carbon monoxide sensors in various fire and unwanted fire conditions should be performed for institutional approval of detection effectiveness. Further research is required to determine the carbon monoxide concentration that can clearly distinguish unwanted fires from actual fires.
