Semiautomatic standpipe systems

[JBI]

Question came up at work today about when a semiautomatic standpipe would be an appropriate choice.
The IBC defines them, but does not 'require' them anywhere and Annex A of the (NFPA 14) Standard provides no specific guidance on when they might be appropriate.

Can any of my esteemed colleagues here provide any information or guidance?

I realize it is the DPR that will specify, but would like to know when it would be an appropriate choice...

I have seen them in open parking garages.

Would say about anywhere you would install a dry pipe, you could install a semi automatic.

Both work about the same.
