Abstract

Optical smoke detectors must be calibrated in order to accurately determine obscurity levels. Engineers from Tyco International identified several disadvantages with previously utilized methods of calibration. This project investigated several potential improvements to the existing techniques, and developed alternative methods of calibrating optical smoke detectors. After conducting extensive research and systematically comparing multiple processes, the method of inserting a reflective surface with a variable angle of refraction was identified as the most appropriate. This paper provides justification for that selection.
