System Description: The Smoke Guard Model 200 (M200) System creates a code-compliant smoke and draft control assembly when paired with common fire-rated elevator doors. The Smoke Guard M200 System screen consists of a reinforced, transparent, polyamide or polyimide film. The film edge is connected to flexible magnetic strips which adhere to ferrous metal rails as the system deploys creating a tight seal.
The Smoke Guard M200 System includes a control system consisting of a printed circuit board containing the control, alarm and diagnostic logic. The M200 uses standard building power and an optional battery backup system if available to maintain operation during building power failure.
The Smoke Guard Model 200 System is designed for application for a maximum hoistway opening of 70-1/2 inches wide, and a maximum ceiling height of 144 inches. Additional installation components are required for openings greater than 55-1/4 inches wide.
System Operation: The Smoke Guard system is designed to protect elevator openings and the shaft from vertical smoke migration. The system will deploy only when the smoke detector in front of that particular elevator opening goes into alarm.

aThis assembly was tested without an artificial bottom seal. The assembly may be installed in areas where pressurization is provided to control smoke movement in accordance with Section 4.3.2 of NFPA 105 (2019) and for hoistway opening protection and lobby doorways as allowed in Chapter 30 of the 2018 IBC.
