Fire sprinkler system

There are several different types of sprinkler systems, depending on the application. These include
Deluge sprinklers—sprinkler heads are always open and the pipes fill with water when activated. Good for hazardous material storage or other areas with high hazards, like aircraft hangars.
Dry pipe sprinklers—pipes fill with water when the system is activated. Since the pipes are dry, this system works well for unheated buildings, like warehouses, where full pipes might burst in cold temperatures.

• Wet pipe sprinklers —pipes are constantly full. These systems are used in high-traffic, high-occupancy buildings like hotels, office buildings, and high-rises.
• Pre-action sprinklers —activated by supplemental fire detection system. Used to mitigate damage of sensitive areas that could be caused by accidental activation. This includes museums, libraries, and the like.
