Introduction

1. INTRODUCTION

The City Mall is protected with the following Fire Protection System.

1. Automatic Sprinkler System.

2. Fire Hose Reel System

3. Portable Fire Extinguisher.

4. Fire Alarm System.

5. Fireman Intercom System.

6. CO2 Fire Extinguishing System.

A. AUTOMATIC SPRINKLER SYSTEM

An Automatic Sprinkler installation is a device contrived for the detection and by the application of water,

extinguisher a fore in its initial stages. It is designed to carry out those functions automatically and its operation

simultaneously causes an alarm bell to sound.

The method of its application is by the action of the Sprinkler head inserted into the system of pipework fitted

throughout the building.

At normal temperatures, the sprinkler glass bulb contains the fluid in both liquid and gaseous phase. As heat is

applied, the liquid expands forcing it to push out against the bulb, causing the glass to shatter, opening the water way

and allowing the deflector to distribute the discharging water.

The necessary features of a satisfactory sprinkler head are briefly as follows :

i. The reliability of operation at its rated operating temperature.

ii. Complete and instantaneous release of the valve and operating parts.

iii. Provision of an even distribution of water over an adequate area.

iv. Simplicity and robustness.

B. FIRE HOSE REEL SYSTEM

Hose Reel provides one of the most effective non-automatic means of extinguishing a fire in its early stage or

containing a large fire pending the arrival of the the fire brigade. It is able to scope with larger fire than portable

extinguisher, and is simple and convenient to handle. The floor distance coverage using Hose Reel usually ranging

from 100 ft. The water pressure is 30 psi at which pressure of 30 ft. jet is produced. In principle, Hose Reel are

strategically located in a building. They are normally housed in cabinets with a graphic board symbol 'HOSE REEL'

conspicuously displayed.

C. PORTABLE EXTINGUISHERS INSTALLATION

Portable Fire Extinguishers is useful when initial Fire-Fighting is called. Various type of Fire Extinguishers are

available for different purposes. Among all Dry Powder extinguisher is commonly used as it is effective for class A

(carbonaceous), B (flammable liquid) and C (flammable gas ) fires. CO2 Fire Extinguishers are used to kill fires

involving flammable liquids and gases. It is non-conductive and therefore particularly effective against fires in

electrical plant and equipment.

Introduction

D. FIRE ALARM SYSTEM

This system mainly consists of detectors, control panel battery and charger. Audible and visual alarm and electrical

power supply which will automatically raise an alarm in the event of the fire, and simultaneously transmit an alarm

signal to the fire control station.

Generally the location of the breakglass manual call point together with 6" Alarm Bell are installed at the passage

way leading to lobby and corridor of the building. The Smoke Detectors are located in the lift lobby area, lift motor

room and air handling unit room. Heat Detectors are normally installed in places where Smoke Detectors are

discouraged e.g. Diesel Generator room and workshop.

An alarm can be activated in the following way:

1. The breaking of manual call point glass

2. The activation of Smoke Detectors or Heat Detectors or both by the presence of fumes smoke created by

combustion.

3. The activation of Heat Detectors due to the accumulation of predetermined heat level in the environment of

burning fires.

4. The activation of the sprinkler system flow Switch.

E. FIREMAN INTERCOM SYSTEM

This system consists of a Master Handset in the main panel control room which is linked to other remote handsets

located at every floor of the building. The purpose of this system is to enable the Fireman to communicate at

different floor level and control station while fighting a fire within the building.

F. CO2 FIRE EXTINGUISHING SYSTEM

CO2 (carbon dioxide) is an odourless and colourless gas. The particular characteristics of this gas make it the

cleanest fire extinguishing method known to date. Carbon dioxide is electrically non-conductive. It is neither caustic,

corrosive nor contaminating. It evaporates without any chemical influence and leaves no residues. The extinguishing

effect is based on the fact that the oxygen content of the air is reduced, thus, choking the fire. This system is installed

in the substation.

This system has been installed, tested and commissioned according to the specification of the Local Fire Authorities.

The Hose Reel system covers the whole building and is installed along the sideway of the building.

This system comprises of the following:

a) Two sets of electric pumpsets.

b) Hose Reel.

c) Shut-off Nozzle

1. HOSE REEL

The Hose Reel is of the swing type. Each Reel is complete with 1" x 50 ft. long non-link rubber hose. The

Hose Reel is finished in black colour which can be easily identified.

2. SHUT-OFF NOZZLE

The shut-off nozzle assembly is constructed from a non-corrosive resistant material conforming to BS336.

3. SYSTEM OPERATION

Opening of any of the Hose Reel nozzle results in a pressure drop in the system. This, in turn, starts the

electric duty pumpset. Should the duty pumpset fails to start, a further pressure drop will operate the

standby pumpset.

Care should be taken to ensure that no Hose Reel can be permitted to be operated for any other purposes. Should the

Hose Reel be used freely, the duty electric pumpset will start and stop frequently thereby increasing maintenance

costs, not to mention the frequent false alarms.

efficiently, the following instructions should be followed :

a. Turn on stop valve to release nozzle.

b. Run out hose.

c. Turn on water at nozzle.

d. Hose Reel should be fully charged with water before winding it into the Drum.

OPERATION OF HOSE REEL STARTER PANEL

GENERAL INFORMATION

The basic function of the Fire Pump Starter Panel for electric motor driven fire pumpsets is to automatically start &

run the motor upon a drop in pressure in the water line.

When water pressure drops below a level which is preset on the internal pressure switch. the pressure switch will

open. The preset pressure switch will trigger the starter panel to start the duty pumpset. Should the duty pumpset

fails to start, a further pressure drop will operate the standby pump. At any time, only one pumpset shall operate. To

stop the pumpset, place the selector switch to 'OFF' position and press the red button 'STOP'. Therefore, the selector

switch must always be restored to 'AUTO' position.

FUNCTION

Equipment is provided in the starter panel to provide the following functions.

AUTOMATIC STARTING FROM Drop in water line pressure.

CONTROL SWITCH A (3) THREE position switch is provided marked 'AUTO—OFF-

MANUAL', to enable motor selection.

DUTY HOSE REEL PUMP

'AUTO OPERATION'

Select A-O-M selector switch to 'AUTO' position. When the pressure in the

water pipelines drops to the preset pressure, the pressure switch will cut in

and the pump will run for a preset time. After the preset time (0-60 sec) if

the pressure increases, the pressure switch will cut off and pump will stop.

DUTY HOSE REEL PUMP

`MANUAL OPERATION'

Select A-0-M selector switch to 'MANUAL' position. Depress the start push

button, the run light will switch on and pump will run. Depress the stop

push button, the pump will stop. During operation, if the pump is

overloaded, the thermal overload relay will trip and the pump will stop. The

trip light will then switch on.

STANDBY HOSE REEL PUMP

'AUTO OPERATION'

C) PORTABLE FIRE EXTINGUISHERS INSTALLATION

a) ABC Dry Powder Extinguisher

This extinguisher is free flowing powder with a composition based on ammonium phosphate and

ammonium sulphates with special additive to improve fluidity and storage.

When discharge, the heat from the fire is greatly reduced. Firstly, because a cloud of powder provides an

effective heat-shield. Secondly, there is an immediately knockdown of the flames. Hence, the flames are

suffocated and any embers are extinguished by a layer of melted powder.

b) CO2 Dry Powder Extinguisher

Carbon Dioxide gas is an efficient Fire Extinguishing agent which offers unique properties to user. The

colourless and odourless gas is heavier than air and works by smothering the flames and reducing the

oxygen content of the air around the fire.

Carbon Dioxide is the ideal agent for use on Class B (flammable liquids) and Class C (flammable gas) fire.

It is non-conductive and therefore particularly effective against fires in electrical plant and equipment.

Carbon Dioxide Extinguisher are used throughout industry as a protection against complex industrial fires

where dangerous chemicals and gases are involved. Carbon Dioxide does not deteriorate with storage or

freeze in the container.

After use carbon dioxide disperses without leaving any contamination or corrosive residue but if used in a

confined area normal ventilation procedure should be followed.

D) FIRE ALARM SYSTEM

Statistic proves that more and more fire are being detected too late for the fire fighting action to be innate in

time. It is the function of the fire alarm system to detect a fire, if possible in its incipient stage and

automatically alert an emergency service to isolate the source of a fire by means of fire protection and local

extinguishing facility.

Quick and reliable automatic alerting depends on the detection element of the automatic fire detectors. To

ensure the proper functioning of fire detectors, the response criterion must be based on the expected

characteristic of an incipient fire.

a) Alarm and Detector

The installation of alarms and detectors-alarm bells of 6" Ø size and operated on 24V DC supply is

such that the system can be actuated by either automatic means or manual means. For automatic actuation,

breakglass or smashing glass callpoint are included. The alarm bell is an audible device which sound in the

event of a fire.

b) Manual Call Point (Breakglass)

'Breakglass' is a device in which a piece of glass needs to be broken or smashed before an alarm can be

initiated in the event of a fire.

9




(E) FIREMAN INTERCOMMUNICATION SYSTEM MAINTENANCE

Minimum Maintenance required. It is a closed supervisory type of system. Therefore, whenever fault occurred

automatic self detection will sound the buzzer with light indication.

F) CO2 FIRE EXTINGUISHING SYSTEM

The Genset Room, MSB Room, Transformer Room & Switchgear Room are protected with CO2 Extinguishing

System.

CO2 (carbon dioxide) is an odourless and colourless gas. The particular characteristics of this gas make it the

cleanest fire extinguishing method known to date. Carbon dioxide is electrically non-conductive. It is neither caustic,

corrosive nor contaminating. It evaporates without any chemical influence and leaves no residues. The extinguishing

effect is based on the fact that the oxygen content of the air is reduced, thus choking the fire. The liquified gas is

stored in high pressure gas cylinder. This cylinder is equipped with an electrical Solenoid actuator control from CO2

control panel. This actuator open the cylinder valve and the CO2 is discharge into the common manifold as well as

into the control piping from which the desired number of follow-up cylinders are pneumatically opened. The CO2

nozzles are open at all times.

INSTRUCTION MANUAL FOR AUTOMATIC CO2 PROTECTION SYSTEM

A. DESIGN SPECIFICATION

1. The installation is designed for extinguishing of fire involving electrical / electronic equipment

hazards and complied to the requirements of Malaysian Fire Protection Association.

2. The quantity of extinguishing agent is carefully predetermined to ensure the fastest possible

extinction of any fire in the protected area.

3. The protected area is provided with normally 50% @ 70 °F concentration of agent in the space of

protected area.

4. Normally a time delay of 25-30 seconds is set for discharge of gas after both two detector zones

receive alarm.

5. The system comprises the following features : -

a) CO2 containers charged with the required quantity of gas.

b) Automatic electric solenoid actuator, manual keyswitch box and manual pull box.

c) Automatic detectors, Alarm bells, Flashing lights & by pass switch.

d) CO2 control panel with 24V Dry Cell batteries and charger.

e) Discharge nozzles, piping and conduit wiring.

f) Discharge warning signboard.

6. The system is installed with 2.27 KG pilot cylinder used to activate all the slave cylinder when the

pilot cylinder is actuated.

B. SYSTEM OPERATION

The installation is operated from automatic mode using smoke/heat detectors under dual mode operation

and manual mode using electric keyswitch. The system is operated by an input voltage of 240V AC 50Hz

supplied to a power charger module within the panel. The AC voltage is transformed and rectified to 24V

DC. A set of Dry Cell batteries is provided as secondary supply in case of AC failure. These batteries will

automatically and instantaneously be switched into use as soon as the mains supply fails. Such a failure is

shown both visually and audibly at the panel. The batteries is trickled charged during normal operating

conditions. The hazard area is protected by two detectors i.e. one smoke and one heat detector. When one of

these detectors receive an alarm condition, a visual and audible warning bell will be given at the control

panel. In order to discharge the extinguishing agent automatically, both detectors must receive alarm

condition. This mode of operation is called 'Double Knock' system with a time delay of 30 seconds preset in

the control panel to discharge the extinguishing agent. This obviates the possibility of false discharge due to

one detector operating.

The facility to discharge the CO2 agent manually is also been provided via manual keyswitch. Also, in the

event of total failure of the control panel, the CO2 agent can still be discharged through mechanical manual

pull station by double action breakglass and follow by pulling the level. The detectors are continuously

supervised by zone supervisory module of the panel for line fault. Any break of wires, the module will both

visually and audibly inform by a fault lamp and buzzer.

Testing,Services&Maintenance

3. SYSTEMS TESTING, SERVICE & MAINTENANCE


This automatic sprinkler system is designed / installed in accordance with the Rules and Regulations of the Uniform

Building By-Laws 1976, Rules of the loss Prevention Council for Automatic Sprinkler Installation BS 5306 Part 2

1990 and subsequents and Jabatan Perkhidmatan Bomba Malaysia.

SYSTEM OPERATION AND CONTROL

This automatic sprinkler system is using a deluge system with wet pilot actuation utilizes the deluge valve in

conjunction with open sprinkler nozzles. The system piping contains no water under normal conditions. Water is

held back by the deluge valve. With "wet pilot” actuation, a network of ½” or ¾" piping with closed ½" orifice

sprinklers is spaced throughout the area of coverage. This "pilot" piping is under water pressure and is connected to

the "wet pilot" (basic) trim of the deluge valve. When the "wet pilot” piping is pressurized / filled with water, the

diaphragm chamber of the deluge valve is also pressurized. This pressure in the diaphragm chamber is exerted to a

piston which forces the clapper lever against the clapper, holding it closed. When a fire activates a pilot sprinkler

detector, water pressure is released through the pilot sprinkler faster than it can be restored due to the restricted

orifice located at the inlet of the diaphragm chamber. This drop in pressure in the diaphragm chamber releases the

lever, allowing the valve to trip. Water enters the system piping and discharges from all of the sprinklers.

It is possible to isolate the sprinkler system via the insolation Rate value.

VISUAL INSPECTION

1. Check all hoses fully charged with water-monthly.

2. Check swivel joint of drum of leakage and ease of movement-monthly

3. Check all stop valves in fully 'open'-weekly.

4. Check for air lock in the system and rectify accordingly.

TESTING PROCEDURES

The Hose Reel system is pressurized by means of pumpsets. Opening of the Hose Reel nozzle result in a

pressure drop in the system. This in turn starts the electric Pumpset.

In order for the user to operate the system efficiently, the following step must be followed:

1. Turn on stop valve to release nozzle.

2. Run out hose.

3. Turn on water at nozzle.

4. Hose should be fully charged with water before it into the Drum.

Each Hose Reel has a minimum flow rate of 6 igpm at 13 psi. Normally 2 sets of Hose Reel are tested at

one time for this specified duty.

A test valve is connected to each of the Hose Reel system in the pump room. Testing of pumpset operation

sequences can be carried out as follow:

1. Operating the test valve slowly and note the system pressure drops.

2. Check the electric Pumpset cut in pressure against the pressure switch setting.

3. Drop the system pressure further until Pumpset cut in.

Maintenance

General Introduction

The indicating panel is available for use in open or closed circuit system, and in either case continually

supervise external wiring to associate alarm initiating devices and alarm sounders.

Control and indicating panel allows the system to be tailored to meet particular requirements by the

addition of standard modules.

Panel interconnection diagram is supplied with each panel and shows panel interconnections and also

typical external wiring to bells, detectors, remote indicators, etc.

NOTE

When installation is completed, the system must be checked by qualified personnel before power is

supplied.

The following text and illustrations explain the operation of a representative control. Though individual

system may differ, all standard features are describe in this publication.

Normal Condition

"Power On" LED illuminated. Should the "Power On" becomes extinguished at any time, this will indicate

a failure of the power supply to the panel or a failure of the LED itself.

Alarm Condition

When an alarm initiating device is operated, the following signal will be given by the control panel.

1. The external alarm sounders will operate.

2. The built in supervisory buzzer will operate.

3. The red LED associated with the zone in which the alarm originated will light.

4. Any ancillary equipment required to be operated for an alarm in that zone will operate e.g. fire

station link. Fan shutdown staircase pressurization, door closed, etc.

23




Alarm Control

a) Fault Buzzer Switch

Operation of this switch silences the external sounders leaving the supervisory buzzer and LED in

operation.

b) General Alarm Switch (Bell Cut off Switch)

This switch is used to convert a local alarm warning in the zone of the alarm to a general alarm

warning throughout the premises.

c) Reset Switch

Operation of this switch resets the control panel after an alarm providing that the alarm initiating

device has been restored to normal.

NOTE

In case of smoke detectors or ionisation type detectors it is important to ensure that all smoke or

product of combustion are purged from the detector before the "Reset Alarm" switch is operated.

d) Trouble Condition

When any one of variety of faults occurs, signals given by the control panel, either singly or

combination, assist in tracing the nature of the fault. These indications are as follow:-

System Trouble Lamp

When the "System Trouble” lamp only is illuminated together with the audible warning from the

built-in supervisory buzzer, it signifies trouble within the panel.

Battery Test

To assist anticipation possible battery deterioration, a battery test facility is provided. If operation

of the "Test Battery" voltage switch produces a battery trouble indication, an inspection of the

battery should be carried out.

e) Possible Causes

1. Open or short circuit on warning to alarm sounders.

2. Low insulations resistance between system wiring and earth.

3. Main supply to charger disconnected or charger faulty.

4. Condition of battery requires investigating.

NOTE All above visual warning indications are accompanied by an audible warning from the built-in supervisory buzzer.
