Elevator shaft enclosure

[sprinkler1000]

Gentlemen:

We are working in a 12 floor office and hotel building.

I understand that elevator shafts constitute a vertical opening that must be protected to provide fire and smoke barrier between the shaft and the floors.(8.6.4 NFPA 101 ed 2012).

Elevator door comunicates directly to the space in underground floors with car parking.

What is the typical way to protect this shaft? I believe that smoke curtains activated by smoke detector is not the standard.
Are the elevator doors intended to be fire rated when the elevator is closed?

Building will have sprinklers.

New or existing building?

Does the ahj consider it a high rise???

This is outside US. The client is following our guidelines.
We are following NFPA 101. The local codes are not very specific on this issue.
Building is new.

not much of an elevator or high rise person

the doors carry a rating built in, but not smoke rating

I am thinking you are in a high rise situation and would need elevator lobby with rated doors

per nfpa 101 2012 check 9.4, and 7.2.13

and also:::


Table 8.3.4.2
Elevator hoistway enclosure has fire resistance rating of 2 hours if connecting four or more stories, and 1 hour of connecting less than four stories

Easy:

Rated elevator lobby with opening protectives that are both fire-resistant and listed as smoke barriers. Provide smoke detection in the lobby with magnetic hold-open devices that release opening protectives (doors) upon smoke detector activation and also recall the elevator.

Thanks all for answering.

The solution is either the swing door or the rolling magnetic gasketing system, in front of the fire rated elevator door, conected to the fire detection system.

Thanks cdafd, very good article.

I work in hospitals a lot and we are supposed to be providing a smoke detector on each floor in the elevator lobby but also a smoke guard needs to be installed. Smoke guard is interconnected with the smoke detector which releases the guard when the smoke detector goes off.
