response time index (RTI) of 50 or less.
Recessed Sprinkler ANSWER>>A sprinkler all or part of the body, other than the shank
thread, is mounted above the ceiling.
Res Home Sprinkler ANSWER >>A type of quick-response sprinkler that is specially
listed for enhancing survivability in the room of fire origin and for listing for use in
dwelling units.
RTI Answer >> A measurement of the thermal sensitivity of a sprinkler head expressed
in meters-seconds (m-s )1/2.
Supervisory signal - A signal indicating the need for action in connection with the
supervision of guard tours, fire extinguishing systems or equipment, fire alarm systems
or the maintenance features of related systems.
Small orifice sprinklers - A sprinkler head with and orifice size smaller than 1⁄2"
Solder Link Sprinkler ANSWER>>Operated by a metal link being melted, there are a few
,sizes and arrangements of these, quick response as well as standard response
sprinklers. The lesser the size the quicker the working of the sprinkler.
Spray Sprinkler ANSWER>>A sprinkler listed on the basis that it can assist in fire control
of a high number of possible fire hazards, most commonly installed since 1953.
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, water level indicator, or low-air pressure switch on a dry-pipe or
pre-action sprinkler system, that initiates 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 A sprinkler which is to be installed in a position such that the water
spray is directed upward onto the deflector.
Water Spray Fixed System A fixed pipe system connected to a dependable fire
protection water supply and equipped with water spray nozzles for specific water
discharge and distribution over the surface or area to be protected. The piping system
shall be connected to the water supply through an automatically or manually actuated
valve that opens to admit water into the system. An automatic valve shall be actuated by
the operation of automatic detection or manual release equipment installed in the same
areas as the water spray nozzles. Special applications may locate the automatic
detection system in another area.
PREACTION SPRINKLER SYSTEMS - 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 automatically opens if a fire detection system sees that
there is a fire or smoke condition. The fire detection system trips the preaction valve
before any of the sprinkler heads open. A supervisory device signals when the valve is
opened. Operation of the preaction valve can also be manual.
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.
Sprinkler heads in deluge system open at all times. There is no water under normal
conditions inside the piping, and air is not under pressure. The flow of water inside the
system is prevented by the closed control valve. Upon determining a fire the fire
detecting device automatically opens control valve. Upon opening, valve supervisory
device sends out the signal. Water flows into the system when the valve is opened. The
water then discharges 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 as needed by pumping water into system thru the Fire Department
connection. Some of these systems are supplied by manual operation of a water control
valve, and may be equipped with either automatic sprinklers, or other type sprinklers,
with, or without, fusible links.
Non-automatic systems include: 1) Perforated pipe systems - a single line of piping
drilled at intervals for water discharge. These systems are usually found in basins or
other areas difficult to reach in fire fighting operations. 2) Fixed spray nozzles, open
type, for transformer vaults or other hazardous areas; 3) Exterior exposure sprinklers
(or window sprinklers) use open sprinkler heads to form an external water curtain on
the walls of a building, and 4) Foam supply systems are used for the protection of
special hazardous occupancies.
Curb Valves - ANSWER>>Gate valves of the non-indicating type are provided in water
distribution systems. Gate valves allow for the sprinkler system to be shut off to be
repaired or maintained. Such valves are usually a non-rising stem type. They are
operated with a special key wrench. A valve box is located over the valve to keep dirt
from the valve. The valve box also provides for a convenient access point for the valve
wrench to the valve nut. A full record should be made for each valve in the system. The
record should include the exact location, the date it was installed, the make, the
direction of opening, number of turns to open, and any maintenance that was
, performed.
The control valve for the building may also be on the outside wall or attached to an
upright post, known as a post indicator valve (PIV). The building or portion of the
building served by the valve usually is identified on the post. The status of this valve,
open or closed, is shown through a telltale opening in the post. On some posts, a
padlock must be opened before the operating wrench or wheel handle can be released.
Fire Department Connections for Pumper Use - ANSWER>>Fire Department
connections shall be available at all times. Each connection shall have a lower check
valve. The lower check valve prevents the private water supply from flowing back into
the Fire Department connection. Figure shows the typical components of a Fire
Department connection.
Fire Pumps - ANSWER>>used as the main source of water supply in sprinkler systems.
They can also be installed with gravity tanks to feed sprinkler systems. Fire pumps take
the water from a supply source and then discharge the water into the fire protection
system under pressure. The amount of pressure the water is discharged from the pump
is called the total head. The total head is measured in pounds per square inch. the
greater the
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 sees changing water
supply pressure must have an alarm retarding device. This prevents false alarms when
a temporary pressure surge lifts the check valve clapper off its seat. Vane type water
flow switches sensitivity may also be set to vary with changing water pressures.
The Centrifugal Pump - ANSWER>>The centrifugal fire pump is the standard pump
currently being used in fire protection systems. It is preferred in fire protection systems
because it is reliable, compact, requires low maintenance, and it can be powered by a
