Clause: Pre Action Sprinkler System. Contract Type. Computer System You must purchase and use any computer system that we develop or select for the Restaurant, including all future updates, supplements and modifications (the "Computer System"). When installing a fire sprinkler system there are three general types, wet-pipe, dry-pipe, and pre-action. A wet-pipe system contains water under pressure at all times and utilized closed sprinkler heads.

Pre-action fire sprinkler systems are best suited for water-sensitive areas such as museums, computer centers, laboratories as they prevent accidental A pre-action sprinkler system is basically a hybrid between different sprinkler systems, particularly wet and dry-pipe systems.

Pre action sprinkler system diagram

Step 3: The pre-action control panel turns into alarm condition and sends a signal to open the solenoid valve. Simultaneously FACP and BMS receives the fire signal (Trouble signal goes to the FACP/BMS at power failure, battery failure and low system pressure in the pre-action control panel) from pre action panel. Preaction systems, particularly the double interlock system, are normally used to protect properties where accidental water discharge is a significant concern. Even though premature or accidental sprinkler system discharge is extremely rare, some property owners prefer these types of systems.
