Wet Systems are the most commonly used sprinkler systems in the fire protection industry. These systems maintain a static water pressure and
are monitored by an alarm device that will actuate if water moves through the pipes. A wet system is your standard fire protection system that
you see in restaurants, office buildings and homes, etc. The alarms on these wet systems are to be tested regularly to assure that if there were
a real fire the system will operate and the alarms will actuate in a timely fashion alerting the fire department of a problem in the building.
