CASE 4: Side Acting Accordion with Power-assisted Egress

Elevator Separation

Elevator car doors are typically fire-rated but cannot comply with smoke and draft requirements. Smoke & draft rated assemblies eliminate the passage of smoke and are usually located at the point of access to an elevator car as an alternative to the elevator lobby.

The single track 3-hour rated accordion will accommodate 18″ radius to custom curves. Along with complying egress, McKEON resolved a very difficult challenge without life safety or design compromise.
