Manual Operation of Smoke Vents

[Glennman CBO]

2009 IBC 410.3.7.1 and section 910 states that both automatic and manual methods of operation are required for smoke vents.

What kinds of manual operations have you all seen in the field, and how is it typically set up? I've never seen this kind of an operation and I'm asking on behalf of an adjacent jurisdiction.

Any comments are appreciated!

We have several that are rope or chain or mechanical linkage to a point where someone can operate it from a floor surface....

most have a pull handle that hangs down into the building.

not much use, especially 30 feet up.

Have seen a very long time ago, one ahj require a cable to be run in conduit to the side of the building. That way no one had to get on the roof, and all they had to do was put a ladder up to the d rings and pull them.. Not to sure of that set up, and code to back it up.

Maybe get with the fire department to see if they want any extra, besides the release hanging down into the building

Thanks,

Now that you guys mention a pull handle, it seems that I have seen something of the sort. I'll check out the various links that North Star posted as well.
