Manual
Automatic Sprinkler
• Listed spray pattern• Sensitive to obstruction
Automatic Sprinkler
• Listed temperature rating
• Listed discharge coefficient
Wet Pipe
• Continuously charged• Immediate discharge
Preaction
• Continuously monitored by compressed air
• Require fire detection system
Single Interlock
• Water charge in system piping upon operation of alarm device
Double Interlock
• Water charge in system piping upon operation of alarm device and sprinkler opening
Preaction sprinkler
• Upright sprinkler• Dry sprinkler• Pendent sprinkler in
return bends and branch lines are above 4C
• Horizontal sidewall sprinkler installed so that water is not trapped

Hydrostatic test• 200 psi (13.8
bar) without loss for 2 hours
• Test pressure shall be read from a gauge located at the low elevation point of the system
Air test (Preaction)
• 40 psi (2.8 bar) with less than 1-1/2 psi (0.1 bar) in 24 hours
Operational test• Open Inspector’s test
connection• Alarm expected
within 5 minutesPreaction• Activate alarm device• Open Inspector’s test
connection• Water discharge
expected within 1 minute
Operational test
• Open main drain valve and leave open until pressure stabilized
• Close and open each control valves under system water pressure
• Open and flow test all pressure reducing valve
Water Spray System
• Open nozzle• Normally empty pipe
Water Spray Nozzle
• Predetermined pattern• Sensitive to wind draft
Required Information

• Discharge test (Automatic, Manual, Emergency)
Clean Agent System
• Carbon Dioxide• Inert Gases• Synthetic Gases
Clean Agent System
• Normally empty pipe• 10 seconds – 60
seconds discharge• Require Automatic
detection and control
Carbon Dioxide
• Stored in liquid or superheated gas state
• No pressure gauge• Quantity check only by
weighing• Flow in two phases• Very low temperature
discharge• Nominal 60 seconds
discharge
Inert Gas
• Stored in high pressure compressed gas state
• Pressure gauge represent gas quantity
• Flow in gas state• Nominal 60 seconds
discharge
