Thank you for helping me.

As long as listed for use, yes. I have used plenty of EC sprinklers in preaction systems.

Is there any specification in NFPA or FM Datasheet

You need the manufactures data sheet for the specific sprinkler you are using,,,

Like this, read the listing and does and donts

https://docs.johnsoncontrols.com/tycofire/api/khub/documents/bib6upf534yLIhjuqkfzTA/content

Plus, I am not a FM person but you need to read the entire data sheet does and donts

Final product storage in the same building??? If so how high to the top of the storage?

Final product will stored on rack protect by ESFR K25.2 in other area , for raw materials in production process not exceed 1.8 meter in high and no more 64 sq.m (approximately four pallets) per 2.3.2 in FM, I can treat it as incidental storage to use Table 2.3.1.10 for protect this area.
Thank you for your advise.

You need to dig into your standards, requirements and datasheets. Most EC are not listed for EH (HC-3) use. There are some K25.2 sprinklers that cover >100 sq ft. You need to do the leg work to find out what is required for your project.
