Automatic fire sprinkler systems are the most common type of suppression system. They are reliable and cost effective.

There are four types of sprinkler systems: wet, dry, pre-action, and deluge.

Wet systems are the most common and are typically found in office buildings, retail establishments, and climate controlled warehouses.
Dry systems are used in environments subject to freezing such as loading docks, attics and parking garages.
Pre-action systems are typically activated by automatic early warning detection and provide an added safeguard against unwanted release. Applications include frozen storage freezers and computer rooms.
Deluge systems utilize open sprinkler heads for hazards requiring the entire system to discharge at the same time for areas like outdoor transformers and fuel loading racks.
