That is simple. Look for one or more air pumps at the sprinkler system riser. The pump(s) will have a gauge, also, in the line showing what the current air PSI may be at any given time. The gauge may be labeled on its face "Air" but it may not be so marked. A sprinkler contractor's test report to the customer will also show whether the whole system is an air system or if it has both air and "wet" systems present in the building.

What's the difference between a wet and dry fire sprinkler system?
The difference is what the pipes normally contain while standing by for a fire.A wet sprinkler system has pressurized water inside the system 24/7 for extinguishing a fire when any sprinkler head gets hot enough to open.A dry sprinkler system has pressurized air or nitrogen inside the piping. This keeps a dry-valve closed, and water out of the system. When a sprinkler fuses (opens), it allows the air to escape; then the dry valve opens and allows water to enter the system. Wherever there is an opened sprinkler, water will flow through it and put out the fire.Dry systems are used in areas where water filled piping could freeze, such as unheated warehouses, freezers, unheated buildings, etc.Additional precautions can also be taken to avoid accidental flooding when a sprinkler head is damaged. For example, a dry-valve controller may wait for a signal from a fire alarm panel before turning on the water.
What is in the piping of a dry sprinkler system?
Normally it is filled with compressed air. A dry sprinkler system is used in areas exposed to temperatures that would freeze water. When a fire is sensed the soft metal link of a sprinkler head melts , releases the compressed air which in turn opens a valve to a fire main allowing the system to flood with water and extinguish the fire. Parking ramps in the northern US have dry systems, for example, because of the weather.
What is a dry pipe sprinkler system?
This system is used in a non heated space. Parking garages, warehouses, carports and so on. The system has pressurized air in the pipeing from the sprinlker head to the water source. Water does not enter the system untell a sprinkler head is set off.
What is a sprinkler system for a house?
A sprinkler system is a device that waters your plants or grass
Will you get a discount on homeowners insurance if you install a sprinkler system?

How often should you replace freon in home sprinkler system?
There is no freon in a home sprinkler system.
Which type of fire sprinkler system is installed wherever the system is subject to freezing?
To avoid problems of freezing water and broken pipes, a "dry sprinkler" system can be installed. The sprinkler heads can be sealed shut with temperature-sensitive valves, as in most wet systems, but the pipes are put under air pressure instead of water pressure, until one of the heads is activated by a fire. Water rushes into the system and sprays out of the open sprinkler head(s) within seconds, if all goes according to plan.
Where is the sprinkler irrigation system found?
Sprinkler irrigation is mostly found in farms.
How does dry riser sprinkler system works?
The heat of the fire causes sprinklers to trip, releasing nitrogen or some other gas held under pressure in the system through the sprinklers. This action activates a dry pipe valve within the sprinkler system which releases fire protection water which has been restrained within the system, through the sprinklers with the intention of dousing if not extinguishing the fire.
How much water is needed for a sprinkler system?
The most common fire sprinkler system is a wet pipe system wich always has water in it. The sprinkler heads have a heat sensitive element, most commonly a glass bulb filled with liquid that expand when exposed to heat, after a certain temperature is met , usually 160 degrees or more the glass bulb breaks and allows water to flow on the fire in a uniform water density. The sprinkler system may have an alarm device that sounds an audible alarm in the building, and/or call the fire department. The system may have a connection for the fire department to add to the automatic water supply. there are other types of systems, dry-pipe, preaction, and others which are similar but do not have water in the piping initally due to concerns of freezing water in the system, or sensitive areas where accidental water damage would be a greater problem than fire.(museums, computer rooms, etc)
