Abstract: A system and method is disclosed for providing a simulation of a flashover condition that can occur during the course of suppression of a live fire. The flashover simulation is implemented by selectively supplying and igniting fuel to an auxiliary or flashover fuel burner assembly positioned adjacent the ceiling of the burn room of a firefighter trainer. Preferably, the flashover simulation is implementable only upon attainment of a threshold value of one or more pre-selected trainer operational parameters that are monitored throughout the course of a training scenario. Preferred trainer operational parameters for such monitoring include flame height at a main burner assembly and air temperature adjacent to or near a ceiling portion of the burn room.

Abstract: A system and method is disclosed for providing control of a fuel-operable burner assembly of a firefighter trainer in accordance with a sensed environmental parameter such as the temperature of an object such as a metal grating or prop that is positioned adjacent to the burner assembly. The control system and method are particularly advantageous to simulate fire reflash following substantial extinguishment of the fire, as operational parameters such as the rate of flame growth, maximum flame height, and reflash delay can be selected and varied from one scenario to the other to modify the training scenario in accordance with such factors as trainee proficiency and the type or class of fire. Burner control is preferably accomplished by an automated processing system in accordance with the foregoing environmental and operational parameters.

Abstract: An assembly for guiding movements of the non-pivotally supported one of a pair of hingedly interjoined bifolding panels, or the like, laterally across a door opening which includes a main body non-rotatably anchored in a mounting socket therefor bored inwardly of the upper or top edge of the one guide panel and including a vertically biased, laterally offset track engaging guide means cooperative with an overhead guide track such that the line of engagement between such offset guide means and the track is in proximity to the free or unhinged lateral edge of the guide panel whereby to increase opening movement of the panels and avoid binding between the track and guide means.
