“Inside Hose” is generally defined as 3/4 or 1 inch rubber hose that may be connected to the sprinkler system for initial fire attack by trained occupants. It's should not be confused with standpipe system which is defined in NFPA-14.
US Approach: It is not common to find inside hose stations these days, unless the owner requires. Most buildings are not required to have such connections. It's not a good idea to install hoses which are usually used by untrained occupants. Americans prefer to only use standpipe system for fire department that is designed in accordance with NFPA 14, whether it is a Class I system with 2-1/2 inch connections or a Class II system with 1-1/2 inch connection or a Class III system with both will have its own water supply and its own calculations. So no need for inside hose stations! European Approach: 3/4" hose reels are commonly used in Europe. I think they accept 60psi. Why is that? I don't know! Which approach do you follow in your country and why? Cheers!
