CASE 5: Vertical Acting with Egress
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.
Typically, the elevator car or elevator shaft door is fire rated but does not carry a UL 1784 smoke rating. The SmokeFighter® D150E is a listed and labeled UL 1784 assembly with a complying egress feature. Located at the point of access to the elevator car, this assembly protects the opening mitigating smoke migration.
