A pre-action system would generally contain the same fluids as any other sprinkler system for those conditions. The "pre-action" merely refers to the method of triggering fluid pressurization prior to activating individual heads.
Wet pipe sprinkler
The best type of well pump for a sprinkler system is a submersible pump. Submersible pumps are efficient, reliable, and can handle the high pressure and flow rate requirements of a sprinkler system. They are also quieter and have a longer lifespan compared to other types of well pumps.
A "deluge" system floods the entire system when sensors detect smoke or heat, and the sprinkler heads do not have individual valves, as would be found in most systems.
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)
Sprinkler glass bulbs typically contain a glycerin-based liquid. This liquid expands when heated, causing the bulb to shatter and activate the sprinkler system. The glycerin is chosen for its reliable thermal expansion properties, ensuring the system responds effectively to fire conditions.
To program a Rain Bird sprinkler system, you will need to follow the instructions provided in the user manual. Typically, you will need to set the watering schedule, duration, and frequency using the control panel on the sprinkler system. Make sure to input the correct settings based on your specific watering needs and the type of plants in your garden.
A site plan or landscape drawing would typically show the location of a sprinkler system. These drawings provide a detailed layout of the property, including irrigation zones, sprinkler heads, and piping. They help visualize the coverage areas and ensure efficient water distribution across the landscape. Additionally, it may include notes or symbols indicating the type and specifications of the sprinkler system used.
To mark sprinkler heads for proper identification and maintenance, use a labeling system that includes the location, type, and maintenance schedule of each sprinkler head. This helps ensure they are easily identifiable and properly maintained.
Could be either, depends on the type of system.

The most efficient system would be to get an under ground drip system. this system used burried lines that feed the roots water.
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.
