A fire fighting simulator includes a projector to project an image of a fire on a screen and a shutter assembly to occlude portions of the image. The extinguishing agent is simulated by an infrared beam and the shutter assembly is controlled to occlude portions at locations impinged by the beam. The control also polls each element of the shutter assembly periodically and opens the elements selectively to simulate reflash of the fire.
