I-TROCTIO-
Fire protection systems are used to alert people that a small fre or some
overheating has occurred, and that there is a danger o fre happening
soon. Active fre protection reers to installing equipment, systems, and
devices that require power to unction such as fre detection, fre alarm,
and fre suppression systems. While the cost o proessionally designed,
installed, maintained, and monitored fre protection may seem large, the
cost o not installing them could be even greater. For small to mid-size
institutions, conventional systems that are simple, reliable, and
economical to install and maintain, will suce. !arger institutions withmore comple" requirements will require more comple" systems. !arger
institutions may have in-house sta# who monitor their systems, and may
also have a bac$up power supply in the event o power loss. %nce
installed, systems need to be inspected, tested, and maintained by a
competent person and in accordance with applicable codes.
&he fre triangle'
Fire is the state o combustion resulting rom a chemical reaction that
requires the presence o three elements in proper combination'
- a uel source (anything that burns),
- o"ygen (a component o air), and
- an ignition source such as heat or a spar$ * in order to
begin and develop.
&his is oten reerred to as a +Fire &riangle+.

SPRE8I-1 OF FIRE
Fire is spread by three methods'
i. 4onvection
ii. 4onduction
iii. 8adiation
Fire is spread by three methods'
i. C$n#e%ti$n
• Fire and smo$e spread by convection is the most dangerous and causes
the ma0or proportion o in0uries and deaths.
• When fre starts in an enclosed space such as a building, the smo$e rising
rom the fre becomes trapped by the ceiling and then spreads in all
directions to orm an ever-deepening layer over the entire room space.
• &he smo$e will pass through any holes or gaps in the walls, ceiling and
oor into other parts o the building.
• &he heat rom the fre gets trapped in the building and the temperature
rises
ii. C$nd&%ti$n
ome materials, such as metal can absorb heat readily and transmit it to
other rooms by conduction, where it can set fre to combustible items that are in
contact with the heated material.
iii. Radiati$n
• 8adiation transers heat in the air in the same way that an electric bar
heater heats a room.
• Any material close to a fre will absorb the heat until the item starts to
smoulder and then burn

TYPES OF SYSTEM:
prin$ler ystems'
Wet prin$ler ystems'
prin$ler systems oten rely on water to e"tinguish the blaze. &he water is
delivered by a networ$ o pipes to the sprin$ler heads, which opened to deliver
the water. prin$ler systems are oten integrated to the fre alarm system, which
warns occupants and summons the fre department automatically. Watersprin$lers are common in oce buildings, retail stores, and heated warehouses.

h&man a%ti#it3.
• t is especially useul in unattended buildings.
• &heheart $0 sprinkler s3stem is the sprinkler head.
• When there is a fre underneath a sprin$ler head, the heat rom the fre
will cause the glass bulb in the sprin$ler head to burst.
• &he glass bulb acts li$e a plug or the pressurized water in the piping
system.
• %nce the glass bulb brea$s, the water shoots out rom the sprin$ler.
• &he sprin$ler rose is designed to spread out the water alling over the fre.
• As in the wet riser system, the pipes distributing the water is constantlyunder pressure.
• A di#erent set o pumps is used to maintain the pressure in the system.
• &he sprin$ler pumps are called duty, stand-by, and 0oc$ey pumps.
• &heir unction is e"actly the same as or wet riser pumps.
• &he only di#erence is in the system they serve.
• ince the sprin$ler system serve unattended areas, it is important that
humans can be alerted whenever they are activated.
• For this purpose, ow switches are installed at each sprin$ler zone.
• Whenever a sprin$ler is activated, water ows out rom the pipes to the
sprin$ler head.
• &he ow o the water through a zone pipe activates a ow switch.
• &he electrical signal rom the ow switch activates an alarm at the 9ain
Fire Alarm panel.
• /ach zone is provided with an isolation valve, a ow switch, and a test
drain valve.
• :epending on the size o the building, there may be several water riser
pipes supplying to all the oors o a building.
• 6ressure gauges, chec$ valves, and alarm gongs are installed in each riser.
• &he alarm gong is actuated by the ow o water through the chec$ valve
and not by electrical signal o the individual sprin$ler zones.

Fire ri'ade S3stem
• When a big fre has occurred in a building, the fre brigade has to be called
in.
• t is important that the road is clear or the fre engines to come in.
• &hereore it is very important or the owner o the building to ensure that
the gates, road, and fre brigade devices are not bloc$ed.
• t is also important that these devices are maintained in good order.
• ome o the fre brigade devices are discussed below'
F$&r"Wa3 rea%hin' Inlets
• A typical high-rise building will have one our-way breaching inlet or
sprin$ler tan$, and one or the wet riser tan$.
• &hey are normally installed near the ground oor or lower ground oor,
where it is easy or the fre engines to come in.
• &hese devices allow the fre brigade to pump water into the tan$s in case
they have been emptied during fre fghting operations.
Street ;3drants
• treet pillars hydrants are provided as an e"ternal source o water besidesthe fre fghting tan$s located in the building.
• &he fre brigade can connect to these pillar hydrants to get additional
pressurized water or fghting the building fre.
Fireman Swit%h
• &here are a ew types o freman switches.
• &hey help to prevent accidents caused by electrical lea$age during a fre
in a building.
• When the frefghters use water hoses to shoot or spray on the fre, it is
rather dangerous or them when the electrical supply is still live.
• &here is a ris$ o electrocution.
• Water can conduct electricity.
• 3isibility is very poor during those times, and the building structures
containing electrical wiring may have collapsed.

:ry prin$lers ystems'
prin$ler systems can also rely on dry chemicals to e"tinguish a fre. &hese are
perect or areas where water might reeze, li$e loading doc$s. For more
inormation on dry chemicals, please see ervices @ pecial 2azards.
6re-Action ystems'
6re-action systems are oten used in storage reezers and computer applications.
&hese systems are activated by an automated detection system. 4harged with
air these pipes prevent the unwanted release o water into the ris$.
&here are several types o 6reaction prin$ler ystems.
;. on-nterloc$
• An automatic sprin$ler control valve (typically a deluge valve) is
activated, by either a sprin$ler head opening or the detection system
activating. Water is discharged into the piping and is discharged out o
the now open sprin$ler (i it has opened).
B. ingle-nterloc$
• &he detection system activates the automatic sprin$ler control valve
(deluge valve), allowing water to ow into the piping system. 2owever,
i no sprin$lers have activated the water remains in the piping without
discharging. sucient heat is created by the fre, on or more sprin$ler
heads will activate. &his wil allow the water to ow out o the sprin$ler
and begin to control or e"tinguish the fre. n addition to a sprin$ler
opening, a supervisory signal is provided to the control panel indicating
a loss o air pressure.
=. :ouble-nterloc$
• Water is only discharged ater two operations have occurred. Coth a
sprin$ler head must open (loss o air pressure) A: a detection device
must activate. When both o these things have occurred, then and only
then with the automatic sprin$ler control valve (deluge valve) open andbegin discharging water into the piping system.
:eluge ystems'
:eluge systems wor$ quic$ly to ood an area with water. &hese are used in areas
where ammable liquids are handled and stored, aircrat hangars, and hazardous
areas where water is the best fre suppression tool. &he rate o water ow is
determined by the predicted fre hazard.

Fire Alarm ystem'
When fre brea$s out, time is o the essence. /arly detection is crucial to save
lives, protect stoc$, and mitigate the damage to your business. Fire alarm
systems can give early warning, allowing or ast evacuation. Automated systems
also contact the fre department, initiate ventilation procedures, and even print a
map to the blaze.
A detection device detects smo$e, heat, and even manual input rom pull
stations. An alarm is then sounded, usually bells or horns. &he alarm device may
be equipped with spea$ers, allowing or voice communications systems.
A typical 9ain Fire Alarm system or a high rise commercial center is designed as
described below'
• A fre control room ftted with a 4entral 6rocessing Dnit ( 46D ) and a
mimic panel.
• &he panel uses !/: to display the location and state o sensors
• i"teen (;E) 8emote 6anel 6rocessing Dnits ( 866D ), mainly located at the
staircases.

Alarm ystem 4omponents'
:etector units rely on a number o clues to determine whether a fre is present.
&hey wor$ to detect heat, smo$e, or ame. ome detect hazardous gases1 others
rely on the rate o temperature increase.
%nce a fre is suspected, a signal is sent to the fre alarm panel. &his panel
receives the alarm signal1 sounds the alarm1 notifes the fre department and
building management1 closes fre doors1 shuts down essential building systems1and starts ventilation devices, i applicable.
An /mergency Warning and /vacuation ystem is designed to evacuate the
building in case o emergency. t is a critical element o any lie-saety system.
&he evacuation alarm is triggered by either a signal rom the fre alarm panel, or
by the activation o a brea$-glass alarm. Warning sirens will sound in relevant
areas, triggering the sae evacuation o personnel.
4onventional-collective'
4onventional-collective detector systems are the most cost-e#ective option. &he
detector units monitor the air or smo$e. 2owever, the detectors can be
conused by non-fre phenomena, li$e tobacco smo$e, steam, and dust. /ach
circuit can contain up to < detectors.
Analogue addressable'
Analog addressable detector systems maintain constant communication with thefre alarm panel. &he protected area is continuously monitored, see$ing changes
7/23/2019 Fire Protector System
http://slidepdf.com/reader/full/fire-protector-system 15/27
in temperature or air quality. the fre is suspected, inormation is sent to the
fre alarm panel which analyzes the signals. &he fre alarm panel decides whether
to trigger the alarm, allowing or sae evacuation o the building. Analogue
addressable systems can also indicate the location o the fre.
pecial 2azard ystems'
Water-based fre suppression systems are the most common and the most cost
e#ective. 2owever, certain applications require special handling. Areas that
contain sophisticated electronics, electrical equipment, or sensitive
documentation require a di#erent system than that used to fght an oil or grease
fre.
Force Fire o#ers a variety o fre suppression systems or any application. We
wor$ with you to design and install a system that meets your needs and budget.
4lean Agent uppression ystem'
4lean Agent suppression system, also called a gaseous system, provides a
waterless alternative to fre suppression. &hat ma$es it perect or areas
containing sensitive electronics and documents, telecommunication and military
equipment. &hereGs no residue, no ood, and no mess to clean up ater. Cest o
all, these gases are sae to breathe, so thereGs no ris$ o su#ocation.
4arbon :io"ide (4%B) uppression ystems'
4arbon dio"ide fre suppression systems are an ine"pensive and e#ective
alternative or large unoccupied areas. &his application is perect or chemical
storage, transormer rooms, turbines, generator plants, and ood manuacturing
acilities. &he gas is stored in tan$s and delivered to the site o the blaze through
a system o pipes.
• 4arbon dio"ide is an inert gas used or putting out fre.
• t does this by displacing the o"ygen that is necessary or combustion.
• Cecause it is a gas, care must be ta$en to ensure that resh air is not
allowed to interere during the process o putting out a fre.
• 4arbon dio"ide is particularly useul when dealing with electrical fres.
• 4arbon dio"ide ooding system is used or switch rooms containing high

• &he rooms will contain live and high voltage electrical supplies.
• &he transormers may contain oil that can burn or e"plode.
• &he only sensible thing to do when fghting this type o fre is to close o#
all the air and displace it with carbon dio"ide.
• With no o"ygen available, the fre will eventually die o#
Carb$n i$(ide Panels
• &hese systems are installed or any room with important electrical or
highly inammable equipment.
• &hey are powered by A4 mains supply.
• tand-by batteries provide ?B hours o operation in case o power

• &hese panels are located near to the rooms to be protected.
• Coth heat and smo$e detectors are installed or such a ooding system.
• &hey have to be activated together beore the 4%B will discharge.
• &his is to prevent alse signals activating the discharging mechanisms.
• &he status o any 4%B panel can be monitored at the 9ain Fire 4ontrol

• &here are two di#erent modes to activate the alarm o the 4%B panels and
subsequent discharge o 4%B rom the cylinders into the room on fre'
8&t$mati% m$de
• Activation o the alarms starts when both the heat and smo$e detectors -
paired up into B zones - have been activated by fre occurring in the

curtain in the room.
• &he curtain above the louver drops down and covers up all o them.
• ometimes the signals may be activated accidentally.
• All the rooms that are so protected have red and green indication lamps
installed above their doors.
• A room that is flled with 4%B does not support combustion.
• Anyone who goes into such a gas-flled room can become unconscious due
to lac$ o o"ygen.
• Whenever gas is discharged, the red lamp above the door will be lighted.
6ersons must enter only when the green light is on.
Waterspray ystems'
Water remains an e#ective and ine"pensive method to fght some types o fre.
Water is cheap and plentiul, and cleanup is easy. &here are no harmul chemicals
to sic$en people. Water spray systems can be delivered using several methods.
%ten, a series o pipes leads to a sprin$ler system.
6re-engineered Foam'
6re-engineered oam fre suppression systems are most commonly used on uel
fres, though are e#ective on a wide range o blazes. &hey create a rothy blan$et

•
6ortable fre e"tinguishers are generally required by code.
• n the hands o trained individuals, they can be an e#ective tool in
e"tinguishing small, contained fres.
• t is important to select the correct type o e"tinguisher or the type o
fre.
• the wrong type o e"tinguisher is used, it could be ine#ective, or even
dangerous, in combating a fre.
• As an e"ample, a water-based e"tinguisher used on a live electrical fre
could result in a serious electrical shoc$ to the person attempting to
e"tinguish the fre.
• used on a ammable liquid or grease fre, the water could cause the
fre to spread.
• &he type o e"tinguisher chosen or a certain area should be based on the
e"pected type o fre or that area.

2ydrants and 2ose 8eel ystems'
Fire hydrants and hose reels provide a ast, e#ective way to deliver largequantities o water to the scene o a fre.
Force Fire starts by analyzing your needs and building to determine the solution
that is right or you. Dsing that inormation, we design a hose reel system that
provides ma"imum protection or your business. We install all necessary
equipment @ water tan$s, pumps, pipes, hose reels, and5or hydrant outlets.
:etectors'
&here are a ew types o detectors that can be chosen to install as a fre
precaution.
6oint :etectors
6oint detectors give the most choice o all systems in the method o operation,
with heat (f"ed temperature and5or rate o rise) smo$e (ionisation or optical),
combined heat and smo$e, or 4arbon mono"ide detection being readily
available. &his enables the system to be tailored to the ris$ being monitored, to
give the best coverage whilst avoiding alse alarms :etectors that are recessed,
or placed above holes in the ceilings, or hidden behind beams and lights are alsoine#ective.

mo$e :etector'
A smo$e detector is a device that detects smo$e. &he smo$e detectors send a
signal to the fre alarm system. 9ost smo$e detectors wor$ by either optical
detection using photoelectric cell or by ionization. &he smo$e detectors are
usually powered by the central fre alarm system which is powered by the
building power with a battery bac$up. &he smo$e detectors will automatically
send a signal to the fre alarm control panel whenever smo$e is detected at the
specifc area so that urther action can be ta$en.

Fire e"it route is the most simple fre protection system. %ccupants are required
to escape rom the building according to the direction o the fre e"it route during
fre emergency. /mergency fre drills will be held rom time to time to ma$e sure
the occupants are amiliar with the fre e"it route.

/"it ign'
/"it signs are signs in a building which show location o the emergency e"it. &he
sign is permanently illuminated as visibility may be reduced due to smo$e or
electrical lighting ailure. Figure B shows an e"ample o e"it sign above the fre
door.
taircase 6ressurization ystem '
&he staircase pressurization system is an important element in the building fre
saety system. &his ob0ective o this system is to create a sae environment in
egress staircases, allowing building occupants to escape the building in a sae
manner. &he main mechanisms by which the stairs are made sae are by
guaranteeing structural protection o the stair enclose and by elevating the
pressure within the stairwell to ensure that smo$e cannot enter. &his can be done
by f"ing a an on the top oor o the stairwell. &he an can be controlled rom the
fre alarm control panel and it will be activated when there is a fre in the buildingso that the staircase will be ree rom smo$e.
Fire !it'
Fire lits are lits that can be used by fre fghters during emergencies to access to
di#erent oors o a building. t is di#erent to a passenger lit as fre lits have
independent power supply. 2ence, when there is a fre outbrea$, the power to
the lobby lits will be shut down and the fre fghters will use the fre lit to
transport themselves and also equipment to the location o the fre.
Fire :oor'
A fre door is a door with a fre-resistance rating (sometimes reerred to as a fre
protection rating or closures) used as part o a passive fre protection system to
reduce the spread o fre or smo$e between compartments and to enable sae
egress rom a building. Fire doors are usually made up o a combination o
materials such as timber, steel, gypsum, vermiculite boards and glass sections.
&he construction o the fre door should comply with 9alaysian tandardsrequirements. Fire doors di#er rom conventional doors as the edges o a fre
door requires fre rated seals such as an intumescent strip which e"pands when
e"posed to heat. All the fre doors are supplied with automatic door closers o the
hydraulic spring operated type. All fre doors have a fre rating which indicates
the fre resistance duration. &here is usually a certifcation nailed on the top right
corner o each fre door.
Fire 2ose 8eel ystem'
A fre hose reel system consists o hose reels normally =<m in length f"ed on
specifc locations on all oors connected to a fre pump set. &he hose has a
control nozzle to control the water direction and water ow. &his system is
7/23/2019 Fire Protector System
http://slidepdf.com/reader/full/fire-protector-system 26/27
pressurised with a purpose o fghting any fre that might occur until the Fire K
8escue ervices arrive. A hose reel is usually provided near to the lit lobby o
every oor enclosed in a door.
4onclusions
Fire is a one o the sub0ect that is always mistreated and ignored as ar as
heritage building is concerned. &hereore, the most e#ective method to eliminate
the ris$s o fre is to conduct a fre ris$ assessment regularly with close
monitoring and reviewing1 i.e. Lprevention is better than cureG. ndeed, academic
bloc$ building owner or manager should play an important role in saeguarding
their building and must possess a good fre saety management.
