Acknowledgements T he Chief Donald J. Burns Memorial Grant provided by the Society of Fire Protection Engineers and funded by Bentley Systems supported this research. Siemens provided equipment and resources such as a customized Fire Alarm Control Panel. The Maryland Fire and Rescue Institute provided resources and facilities to accomplish full-scale fi re testing. Dr. Darryl Pines, Dean of the Clark School of Engineering, provided seed funding in support of this research. I would like to thank my thesis advisor, Professor André Marshall, for his sup- port and guidance throughout the duration of this project. I appreciate his ability to envision the future goals of the project while also providing clear guidance on cur- rent specifi c tasks. I would also like to thank Professor Arnaud Trouvé and Professor Stanislav Stoliarov for being on my committee and providing me valuable guidance. None of this would have been possible without the support of Professor Jim Milke for the past 5 years. I sincerely thank him for his genuine encouragement, insightful advice, and great sense of humor. vii Contents 1 Introduction
