When the video studio where I work was relatively new it had an infrared beam smoke detector with an emitter in one corner and a detector in the opposite corner. Our engineer rigged a red strobe light for an "on air" light and when he tested it it set off the smoke detector, and the fire alarm in the whole building. It was a stupid design. Whenever we moved a light batten it performed the same trick. They eventually replaced it. I don't know if a regular camera flash would do the same but it might under the right circumstances.
