The McKeon SmokeFighter D100 is manufactured from protective curtain assembly material that has been tested and certified under UL 10B, 10C, 10D and UL 1784; and approved to span unlimited widths and heights up to 24 feet. The test criteria included side guides, however, the test parameters for draft curtains do not require any of the above certifications except to resist the passage of smoke. Thus, the McKeon D100 exceeds the fire and life safety requirements for draft curtains in the building code.
A draft curtain is commonly used in large spaces where smoke management is a challenge. In these type of applications draft curtains typically work in conjunction with smoke and heat vents. These vent systems are not the same as active smoke evacuation systems, rather they are designed to minimize smoke movement and provide temporary tenable environments until building occupants can evacuate during a fire or emergency.
