A magnet will adhere to or be attracted to a frame constructed of ferrous materials. Iron and steel are examples of ferrous materials. The Smoke Guard system (SGS) curtain requires a 2-inch wide continuous flat ferrous metal surface for deployment.
Stub rails are short versions of our full-length ferrous metal rails used to span the distance between a ferrous metal elevator door frame and the bottom of a Smoke Guard System (SGS) housing to maintain the continuous ferrous metal surface required for system deployment.
No. The Smoke Guard system (SGS) provides a smoke- and draft-control assembly for the fire-rated elevator door frame. The SGS is a smoke resistant gasket mounted on the face of the elevator doorframe which allows the elevator to function without interfering with elevator door operation.
The release mechanism of the Smoke Guard system (SGS) is connected to a UL listed smoke detector (UL Standard 268) required by code at the elevator landing. When smoke is detected, the release mechanism activates SGS deployment. The SGS curtain covers the elevator openings on the floor where smoke was detected.
