![]() 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. The system will deploy only when the smoke detector in front of that particular elevator opening goes into alarm.ĪThis assembly was tested without an artificial bottom seal. System Operation: The Smoke Guard system is designed specifically to protect elevator openings and the shaft from vertical smoke migration. Additional installation components are required for openings greater than 55-1/4 inches wide. The Smoke Guard M400 and M400B System application designs are for a maximum hoistway opening of 70-1/2 inches wide, and a maximum ceiling height of 144 inches. When opening the doors of the elevator shaft, this draft is clearly felt. The M400B System uses standard building power and an integral battery backup system to maintain operation during building power failure. Smoke detector activated elevator door smoke containment curtain and control system designed to provide a tight-fitting, smoke- and draft-control assembly. The M400 System uses standard building power. The curtain and the operating system, including the controls, junction box, and reserve battery. The Smoke Guard M400 and M400B Systems include a control system consisting of a printed circuit board containing the control, alarm and diagnostic logic. Cookson Door now offers custom elevator smoke curtains. Elevator car doors are typically fire-rated but cannot comply with smoke and draft. The elevator hoistway shall be pressurized in accordance with Section 909.21. CASE 2: Side Acting Accordion with Manual Egress. The film edge is connected to flexible magnetic strips which adhere to ferrous metal rails as the system deploys creating a tight seal. Such door shall comply with the smoke and draft control door assembly requirements in Section 716.2.2.1.1 when tested in accordance with UL 1784 without an artificial bottom seal. The Smoke Guard System screen consists of a reinforced, transparent, polyamide or polyimide film. It may, therefore, be necessary to construct an elevator lobby as is allowed by Section 1020. ![]() the already fire-rated elevator hoistway door to form a smoke- and draft-control.

Smoke-Tech provides the absolute best smoke barrier protection and draft control available, and provides you with a high quality, functional, aesthetically pleasing opening. ![]() Curtains like Smoke Guard’s elevator smoke containment systems can easily create the code equivalent of an enclosed elevator lobby.Ĭlick here to read about the use of Smoke Guard curtains in Ocean Towers, a luxury residential high-rise in Santa Monica, California and learn how architects were able to meet building codes without sacrificing much-needed space.System Description: The Smoke Guard Model 400 and Model 400B (M400 and M400B) Systems create a code-compliant smoke and draft control assembly when paired with common fire-rated elevator doors. The Smoke Guard System is designed to temporarily seal an elevator. ![]() Today, installing smoke and fire curtains at the elevator jamb can protect the elevator shaft without the need of an enclosed lobby, saving important design space. To meet this air leakage test, the doors or opening protectives that serve as smoke and draft control assemblies must be designed to fit snugly in the space. But this was often costly to design and difficult to plan around when it came to traffic flow and space requirements. Penetrations in addition to those permitted in section 27-353.3 (smoke barrier) shall be provided with smoke dampers as defined in reference standard RS 13-1, except that a package pass through or communication opening not exceeding one square foot in area need not be provided with smoke dampers.
