  • Patent number: 9384673
    Abstract: An emergency simulation device has a housing, at least one light, a smoke machine, and a controller for controlling the light and the smoke machine. The housing has a divider with a generally enclosed area underneath for holding the smoke machine. The divider has a hole and is angled so that water sitting on the divider flows in at least one direction. The housing extends upwardly beyond the divider, and apertures positioned in the housing dispel water from atop the divider. The housing has a duct extending upwardly from the hole in the divider. The light is mounted to a mounting plate separate from and positioned above from the divider and the duct and below a top end of the housing. The smoke machine outputs smoke through the hole in the divider and the duct. The mounting plate causes the smoke to billow outwardly around the light.
