I would like to dedicate this report
to my parents, Sarah and Joe Wills,
for their lasting love and support for
me and for my aspirations.
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.
