Standard Response Sprinkler Head - ANSWER- A sprinkler having a fusible link with a response time index (RTI) of 80 or more. Supervisory signal-initiating device - ANSWER- An initiating device, such as a valve supervisory switch,that triggers a supervisory signal. Testing - ANSWER- A procedure used to determine the status of a system as intended by conducting periodic physical checks on water based fire protection systems such as waterflow tests, fire pump tests, alarm tests, and trip tests of dry pipe, deluge, or preaction valves. These tests follow up on the original acceptance test at intervals specified in the appropriate chapter of NFPA #25, 2002 edition. Upright Sprinkler - ANSWER- A sprinkler designed to be installed in such a way that the water spray is directed upwards against the deflector. Water Spray Fixed System - ANSWER- A special fixed pipe system connected to a reliable fire protection water supply and equipped with water spray nozzles for specific water discharge and distribution over the surface or area to be protected. PREACTION SPRINKLER SYSTEMS - ANSWER- designed for situations where there is danger of serious water damage. Water damage is usually caused by damaged sprinklers or broken piping. Under normal conditions there is no water in the piping. The air in the piping may or may not be is under pressure. A preaction valve prevents the water from entering the system. The valve is
preaction valve is tripped by the fire detection system before any of thesprinkler heads open. A supervisory device signals when the valve is opened. The preaction valve can also be operated manually. DELUGE SPRINKLER SYSTEMS - ANSWER- equipped with open sprinkler heads designed to wet down an entire area involved in a fire. This system is needed when there is danger of a fire rapidly spreading throughout the building. The deluge system will slow down the spread of the fire. Deluge systems are suitable for hazardous occupancies. This includes buildings in which flammable liquids or other hazardous materials are handled or stored. The sprinkler heads in the deluge system are open at all times. Under normal conditions there is no water in the piping. The air in the piping is not under pressure. A closed control valve prevents water from flowing into the system. A fire detection device automatically opens the control valve when a fire is identified. A supervisory device signals when the valve is opened. When the valve is opened water flows into the system. The water is then discharged out all of the sprinkler heads. The water control valve may also be opened manually. NON-AUTOMATIC DRY SPRINKLER SYSTEMS - ANSWER- ll pipes are normally dry. Water is supplied when needed by pumping water into the system through the Fire Department connection. Some of these systems are supplied by manual operation of a water control valve and may be equipped with sprinklers with or without fusible links. There are several non-automatic systems: 1) Perforated pipe systems - a single line of piping drilled at intervals for water discharge. These systems are usually found in basements or other areas difficult to reach in fire fighting operations. 2) Open
fixed spray nozzles for transformer vaults or other hazardous areas; 3) exterior exposure sprinklers (or
Fire Pumps - ANSWER- used as a main water supply source for sprinkler systems. They may also be used in combination with gravitytanks to supply sprinkler system. Fire pumps are designed to take the water from a supply source and then discharge the water into the fire protection system under pressure. Waterflow Alarm Valves - ANSWER- The basic design of most water- flow alarm valves is that of a check valve which lifts from its seat when water flows into a sprinkler system. This alarm then starts an audible signal to alert the occupants in the building that the sprinkler system has been activated. Vane type waterflow - ANSWER- Switches have a paddle inserted inside the main supply piping perpendicular to the direction of flow. Upon waterflow, the paddle switch transmits an alarm. Vane type waterflow switches cannot be installed to monitor waterflow in dry pipe sprinkler systems. Alarm Retarding Devices - ANSWER- An alarm check valve that is exposed to changing water supply pressure needs an alarm retarding device. This is required to prevent false alarms when the check valve clapper is lifted from its seat by a temporary pressure surge. Vane type water flow switches sensitivity can also be adjusted to changing water pressures. The Centrifugal Pump - ANSWER- The centrifugal fire pump is the standard pump currently used in fire protection systems. This is the preferred pump because it is reliable, compact, requires low
maintenance, and it can be powered by a variety of drivers including: electric motors, internal combustion engines, and steam turbines The Vertical Turbine Pump - ANSWER- A vertical turbine pump is really a modified centrifugal pump that has the capability to draw water from streams, ponds, wells etc. Unlike the standard centrifugal pump, the vertical turbine pump does not need the suction supply to be under pressure for it to operate. Instead it draws the water into the pump by suction. The water is drawn into the pump. When it reaches the rotating impellers the water pressure is increased and then forcefully discharged into the fire protection system. Pump Activation - ANSWER- A fire pump can be started automaticallyor manually. The pump can be started automatically by an electric controller or an engine controller. These controllers activate the pump when there is a drop of water pressure or water flow in the fire protection system. Pressure Maintenance Pumps (Jockey Pumps) - ANSWER- Pressure maintenance pumps, Some times referred to as jockey, or makeup pumps, are often found on sprinkler systems. These pumps are designed to automatically operate when there is a slight drop in pressure due to the leakage in the system or a pressure surge. The jockey pump restores the pressure in the fire protection system to the desired level. When the drop of pressure in the system greater than the capacity of the jockey pump the fire pump is activated.
fire hydrant - ANSWER- A valve connection on a water supply system having one or more outlets and that is used to supply hose and fire department pumps with water. Control valve - ANSWER- A valve controlling flow to water base fire protection system. Control valve do not include hose valves Fire pump locations - ANSWER- the fire pump should be located in a place that is noncombustible or fire resistant. has to be heated to a minimum of 40 degrees Fahrenheit.

Fire Hydrant - ANSWER- A valve connection on a water supply system having one or more outlets and that is used to supply hose and fire department pumps with water. Fire Pump - ANSWER- A pump that is a provider of liquid flow and pressure dedicated to fire protection. A fire pump is a part of a fire standpipe system's water supply and can be powered by electric, diesel or steam. The pump intake is either connected to the public underground water supply piping or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at higher pressure and volume to the standpipe system risers and hose standpipes. A Fold is a - ANSWER- A transverse bend (fold) occurring where the hose is lengthwise double over on itself, as on a pin rack.
