More specifically, backflows are not fire protection devices, which is why they are not prescribed by the sprinkler standard. The local health and water departments are the enforcing agencies with regard to backflow prevention and cross-connection control, and generally speaking a backflow appliance is only required to be installed on a private connection to the public water system that will supply a non-potable demand. So in 99+% of scenarios, the installation of a strainer would be governed by the serving water agency since it occurs on the public side (and often in the public right-of-way) of the backflow appliance. Questions you have about such equipment should be directed to the cross-connection control department of the water purveyor.

They are included in-so-far as municipalities dictate them. Therefore, the data sheet is the only real refuge for the info. As per yours below, do not use a strainer on our systems.

I found on the backflow submittal where it states it, but is it in NFPA 13 and possibly UFC 03-600-01?
