Questions and Answers 100% Pass
Alarm Notification Appliance - ✔✔A fire alarm system component that issues an

Eg. A bell, horn, speaker, light, text display or vibration device
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. The antifreeze solution
is 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 valve. It automatically reopens when pressure ceases, permitting this

Concealed Sprinkler - ✔✔A recessed sprinkler with a cover plate
Control Mode Specific Application Sprinklers (CMSA) - ✔✔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 do not include hose valves, trim valves for dry
pipe, preaction and deluge valves, check valves, or relief valves
OS & Y valve (outside stem and yoke valve) is an indicating type of control valve
