Patent 7471049 was granted and assigned to SimplexGrinnell on December, 2008 by the United States Patent and Trademark Office.
Optical element driving circuits flexibly configure energy sources to cause a flash tube to produce illumination at one of multiple output intensities. The driving circuits allow a single strobe alarm to take the place of multiple strobe alarms individually dedicated to specific output intensities. The driving circuits may also mitigate or eliminate high voltage arcing within the driving circuit.
