This is a basic training on Fire Detection and Alarm System, created to give my colleagues from non-engineering divisions a comprehensive brief on the system. This is most suitable for individuals with little or no technical knowledge. This training introduces the devices and the system in a whole, not how to design it.

5. Elements of Fire
Fire Triangle
Three elements a fire needs to
ignite:
1. HEAT,
2. FUEL,
3. OXYGEN
Can be prevented or
extinguished by removing any
one of the elements in the fire
triangle
5
6. Elements of Fire
Fire Diamond
Once a fire has started,
the resulting exothermic
chain reaction sustains
the fire and allows it to
continue until or unless
at least one of the
elements of the fire is
blocked.

7. Classes of fire
Class A - fires involving solid materials such as
wood, paper or textiles.
Class B - fires involving flammable liquids such as
petrol, diesel or oils.
Class C - fires involving gases.
Class D - fires involving metals.
Class E - fires involving live electrical apparatus.
(Technically ‘Class E’ doesn’t exists however this is
used for convenience here)
Class F - fires involving cooking oils such as in
deep-fat fryers.

and certification company
UL is one of several
companies approved to
perform safety testing by the
U.S. federal
agency Occupational Safety
and Health
Administration (OSHA).
What is “UL Listed”?
15
16. What is “FM Approved”?
independent testing arm of
international insurance carrier,
FM Global.
FM approvals uses scientific research
and testing to make sure products
conform to the highest standards for
safety and property loss prevention.
Products that pass get the “FM
APPROVED” mark. Think of it as like
the Good Housekeeping seal of
approval, only better.

18. The Origin of Fire Alarm
Long ago, as an early method of spreading
the word of fire danger, people shouted
"Fire!"
The Town Bell Or Other Noisemaker Was
Also Used.
Electricity was discovered
and electrical (and electronic) fire alarm
systems were developed.
18
19. How a Fire Alarm Works
Basically, to activate it, a fire alarm system uses
manually operated devices (pull stations), or
automatically activated devices (smoke and heat
detectors, waterflow switches, etc.).
Once a fire is discovered by the fire alarm
system, it tells the occupants of a building about
the fire (by making lots of noise and flashing
lights), and calls the fire-fighters (through
automatic communication).
After that, it is up to the occupants to defend
themselves from the fire, and the firefighters to
try to extinguish it.

32. INITIATING DEVICES
• Manual initiating devices – break glass station, buttons,
pull stations and the like are all considered manual
initiating devices. They should be located near the exits of
your building and should be easily accessible, identified and
operated.
• Automatic initiating devices –wide variety of automatic
initiating devices, including heat detectors, smoke
detectors, flame detectors, CO detectors, water flow
detectors, etc.
• Sense changes in the environment and react automatically
• May use cameras and computer algorithms to analyze
visible effects of fire and movement in ways that other
detection devices can’t.

37. PHOTOTECTRIC DETECTOR
Light Scattering Principle
• These detectors use a Light-Emitting
Diode (LED) that sends a beam of light into a
dark chamber. A photo diode sits on the other
side of a partition within the chamber.
• Smoke particles entering the chamber deflect
some of the light rays into the photocell. The
photo cell generates a current when exposed to
light, and if the current reaches a certain level,
the smoke detector alarms.
37
38. Typical Range
Simplex TrueAlarm photoelectric sensors use a
stable, pulsed infrared LED light source and a
silicon photodiode receiver to provide consistent
and accurate low power smoke sensing. Seven
levels of sensitivity are available for each
individual sensor, ranging from 0.2% to 3.7% per
foot of smoke obscuration. Sensitivities of 0.2%,
0.5%, and 1% are for special applications in
clean areas. Standard sensitivities are 1.5%,
2.0%, 2.5%, 3.0%, and 3.7%. Application type
and sensitivity are selected and then monitored
at the fire alarm control panel.
38
41. A smoke detector is a particle
detector so:
• Do not install in dusty/dirty
environments
• Do not use outdoors
• Do not spray with aerosols.
• Work such as carpentry, welding, and
grinding can cause nuisance events.
SMOKE DETECTOR –
NUISANCE EVENTS
41
42. LASER TYPE DETECTORS
•Used for Early Warning Smoke
Detection
•Uses a Laser Light Source and
receiver
• Sensitivity is higher (0.02% to 2%)
•As per NFPA 318/76 Spot type Laser
Smoke Detectors are for “high value
asset protection”.
42
43. Projected Beam Principle
Smoke from the
fire in the protected
area diffuses the
intensity of the beam at the receiver
Transmitter Receiver
43
44. In a projected Beam Detector, alarms are
generated by diffusing the projected light beam
by a specified percentage of obscuration.
Total beam blockage generally results in a trouble
signal.
Wire the receiver unit as a 4-wire detector
(separate power and sensing connections to
the control panel).

ASD (Aspirated Smoke Detection)
ASSD (Air Sampling Smoke Detection)
VESDA (Very Early Warning Aspirating Smoke
Detection)
FAAST (Fire Alarm Aspiration Sensing
Technology)
Works much like a vacuum cleaner. Sucks air
from the protected environment via purpose
built aspirating pipe and fittings and samples
the quality of air passing through the detection
laser chamber.
46
48. ASD PRINCIPLE
ASD technology utilizes
collective air sampling vs.
point detection
A sample of air is collected
from multiple sampling holes
Areas of coverage and spacing
are the same for both
=Sample Hole
48
51. Reliability Benefits
Excellent false alarm immunity to dust,
steam, insects, objects and structural
movement
Eliminates false alarms by automatically
compensating for building movement
No moving motor parts eliminates hardware
failures
Operates in all ambient lighting conditions
Not affected by nearby reflecting surfaces
No false alignment due to reflecting on fog
Ability to compensate for high air movement 51
52. Financial Benefits
Low implementation costs because of simple
and fast installation and alignment
-Only the Imager unit has to be
wired (battery powered Emitters)
-Power can be supplied from panel
-Fast and simple coarse manual
alignment
Lower maintenance cost for larger areas
-Test filter at the Imager or Emitter
-No intervention costs for misalignment

55. Duct Detectors
Photoelectric detector mounted in
housing outside the ductwork that has
probes that extend into the duct to
sample the air inside the duct.
Primarily used as a smoke control device
to control the flow of air in ductwork.
55
58. Heat Detectors
Heat detectors are the oldest type of automatic
fire detection device.
Not considered direct Life Safety devices, these
detectors do contribute to the detection of a fire.
58
60. Heat Detectors
FIXED TEMPARATURE
Initiates alarm when the sensing element reaches
a certain set point.
Two common ones have 135 and 200-degrees F
range. The Fixed element is generally a non-
restorable type, and when activated, must be
replaced.
Typical Range: Fixed temperature sensing is
independent of rate-of-rise sensing and
selectable to operate at 135° F (57.2° C) or 155°
F (68° C).
60
61. Respond when the rate of temperature increase
is greater than an allowable limit
Typical Range: Rate-of-rise temperature
detection is selectable at the control panel for
either 15° F (8.3° C) or 20° F (11.1° C) per
minute.
In a slow developing fire, the temperature may
not increase rapidly enough to operate the rate-
of-rise feature. However, an alarm will be
initiated when the temperature reaches its
selected fixed temperature setting.
Heat Detectors
RATE OF RISE TEMPARATURE
61
63. LINEAR HEAT DETECTOR
There are many situations when
conventional heat or smoke fire detectors
only work to a limited degree, if at all.
For example; dusty or dirty areas, areas
with exhaust fumes, areas with high
humidity, freezing fog, or areas subjected
to high vibration.
Also, if there is no access to the detectors
after installation, a maintenance-free
sensor would be desirable.
