• Alarm Signal -✓✓a signal indicating an emergency requiring
immediate action, such as a signal indicative of fire
• Antifreeze Sprinkler System -✓✓A wet pipe sprinkler system
employing automatic sprinklers that are attached to a piping system
that contains an antifreeze solution and is connected to a water supply;
discharged followed by water, immediately upon operation of
sprinklers opened by heat from a fire
• Automatic Ball Drip -✓✓An automatic drain valve horizontally
installed at the low point in the piping between the lower check valve
and the FD connection of automatic sprinkler systems. Water pressure
from a FD pumper automatically closes this value. It automatically re-
opens when pressure ceases, permitting this piping to drain and
thereby preventing freezing
• Central Station -✓✓facility that receives alarm signals from a
protected premises and retransmits or otherwise reports such alarm

• Controle Mode Specific Application Sprinklers -✓✓Control mode
sprinkler systems are designed to control a fire until its original fuel
source is depleted or until fire-fighting activities can commence. A fire
is controlled by cooling the ceiling-level air temperatures, reducing the
fire's rate of heat release and pre-wetting adjacent combustibles
• Control Valve -✓✓a valve controlling flow to water-based fire
protection systems. Control valves do not include hose valves,
inspector's test valves, drain valves, trim valves for dry pipe, reaction
and deluge valves, check valves, or relief valves
• OS & Y Valve -✓✓an indicating type of control valve used for fire
sprinkler system
• Curb Valve -✓✓non-indicating gate valve equipped with a cast iron
