Thanks to all for helping me with my question, according to your valuable
comments I concluded that I should try the followings:
I think an option is talking to a well known sprinkler manufacture to see if
they can offer an extended coverage sprinkler suitable for my application,

One more thing, make sure that your churn pressure on the pump plus
the elevation gain going down the two levels does not exceed 175 psi.
This may be the pressure the system feels when the system first trips
(or in the case of an accidental trip)

Hi All,
Dears friends Craig, Travis, Kurt Todd,
Many thanks for your detailed answer, your answers were very helpful,.
I will use the sprinkler piping for my fire hoses to save some pipe, after
calculation, the water velocity in piping is about 20 ft/s and the capacity of
sprinkler piping in each

It's not often that we all get to see the fruits of our labors.
In 1986 I designed a dry pipe system for a 7-8 level parking garage for a

Reza,
If it doesn't work and you have to install two extra dry valves, that
would most likely be a very expensive operation. Is it worth the
chance? As Clint Eastwood once said, Do you feel lucky?

Consider low pressure DPVs if you have no way to determine trip time
(the expensive program). low pressure DPVs work on about a 30:1
differential rather than the more typical 6:1.

A few random comments:

(like EC-11) have worked out well on a few recent jobs but you really
start accumulating over discharge on the branch lines quickly with the
higher end head pressures. That issue also tends to fight
Reza,
1- What is your recommended Area of sprinkler operation and Density
for my application after determining from the Density/Area curve?
ANSWER: .15/1500 works but don't forget to increase the design area by
30% due to it being a dry system. So you would have .15/1950 sq. ft
