I would be cautious mixing then. If a fire event were to occur where it
activated both, you could get into issues with pressures.
Just throw a calc on the area and see if you get minimum pressures/flows
required. The system will balance to the higher pressures so something
will over discharge and that may kill your sizing.
However, after a long holiday break, I could be totally crazy as well.

We do it when we have high bays that require the larger k-factor and then
lower roof areas that the smaller works.

Looking at a 400,000 sq.ft. building with multiple storage
arrangements, on the floor, on single and double row racks. Each about
half the building.
Can you use K25 ESFR heads for the rack storage (exposed expanded
Group A
plastics) and K17 heads for the storage on the floor (class 4
commodities)?
Thoughts as I cannot find anything that says you can't.
Thank you
