Fire Alarm System Limitations
An automatic fire alarm system–typically made up of smoke
detectors, heat detectors, manual Call Points, audible warning
devices, and a fire alarm control with remote notification capability–
can provide early warning of a developing fire Such a system,
however, does not assure protection against property damage or loss
of life resulting from a fire The Manufacturer recommends that smoke
and/or heat detectors be located throughout a protected premise
following the recommendations of of IS 2189: 1999 and any other local
codes of practice that are applicable While fire alarm systems are
designed to provide early warning against fire, they do not guarantee
warning or protection against fire A fire alarm system may not provide
timely or adequate warning, or simply may not function, for a variety
of reasons:
Smoke detectors may not sense fire where smoke cannot reach the
detectors such as in chimneys, in or behind walls, on roofs, or on the
other side of closed doors Smoke detectors also may not sense a fire
on another level or floor of a building A second-floor detector, for
example, may not sense a first-floor or basement fire
Particles of combustion or "smoke" from a developing fire
may not reach the sensing chambers of smoke detectors because:
• Barriers such as closed or partially closed doors, walls,
or chimneys may inhibit particle or smoke flow
• Smoke particles may become "cold," stratify, and not
reach the ceiling or upper walls where detectors are
located
• Smoke particles may be blown away from detectors by
air outlets
• Smoke particles may be drawn into air returns before
reaching the detector
The amount of "smoke" present may be insufficient to alarm smoke
detectors Smoke detectors are designed to alarm at various levels of
smoke density If such density levels are not created by a developing
fire at the location of detectors, the detectors will not go into alarm

Smoke detectors, even when working properly, have sensing
limitations Detectors that have photo electronic sensing chambers
tend to detect smoldering fires better than flaming fires, which have
little visible smoke Detectors that have ionizing-type sensing chambers
tend to detect fast-flaming fires better than smoldering fires Because
fires develop in different ways and are often unpredictable in their
growth, neither type of detector is necessarily best and a given type
of detector may not provide adequate warning of a fire
Smoke detectors cannot be expected to provide adequate warning
of fires caused by arson, children playing with matches (especially in
bedrooms), smoking in bed, and violent explosions (caused by
escaping gas, improper storage of flammable materials, etc )
While a fire alarm system may lower insurance rates, it is not a
substitute for fire insurance!
Heat detectors do not sense particles of combustion and alarm only
when heat on their sensors increases at a predetermined rate or
reaches a predetermined level Rate-of-rise heat detectors may be
subject to reduced sensitivity over time For this reason, the rate-of-rise
feature of each detector should be tested at least once per year by a
qualified fire protection specialist Heat detectors are designed to
protect property, not life.
IMPORTANT! Smoke detectors must be installed in the same room as
the control panel and in rooms used by the system for the connection
of alarm transmission wiring, communications, signaling, and/or
power. If detectors are not so located, a developing fire may
damage the alarm system, crippling its ability to report a fire
Audible warning de ices such as hooters and bells may not alert
people if these devices are located on the other side of closed or
partly open doors or are located on another floor of a building Any
warning device may fail to alert people with a disability or those who
have recently consumed drugs, alcohol or medication

Please note that:
• Strobes can, under certain circumstances, cause seizures in people
with conditions such as epilepsy
• Studies have shown that certain people, even when they hear a fire
alarm signal, do not respond or comprehend the meaning of the
signal It is the property owner's responsibility to conduct fire drills and
other training exercise to make people aware of fire alarm signals and
instruct them on the proper reaction to alarm signals
• In rare instances, the sounding of a warning device can cause
temporary or permanent hearing loss
A fire alarm system will not operate without any electrical power If AC
power fails, the system will operate from standby batteries only for a
specified time and only if the batteries have been maintained
properly
Equipment used in the system may not be technically compatible with
the control panel It is essential to use only equipment listed for service
with your control panel
The most common cause of fire alarm malfunction is inadequate
maintenance To keep the entire fire alarm system in excellent working
order, ongoing maintenance is required as per the manufacturer's
recommendations Environments with large amounts of dust, dirt or
high air velocity require more frequent maintenance A maintenance
agreement should be arranged through the local manufacturer's
representative Maintenance should be scheduled monthly or as
required by National and/or local fire codes and should be performed
by authorized professional fire alarm installers only Adequate written
records of all inspections should be kept

1.3 Fire Alarm Procedures
In accordance with IS 2189: 1999, written procedures should be laid
down for dealing with alarms of fire, fault warnings, and the isolation of
any part of the system The responsible person should ensure that users
of the system are instructed in its proper use and are familiar with the
procedures
On hearing the fire alarm:
CARRY OUT THE PRESCRIBED PROCEDURE Subsequent actions will
depend on the circumstances, and may include silencing the audible
alarms and resetting the system, as described later
Fault Indication:
If the control panel indicates a Fault condition, make a note of all
illuminated indicators, refer to the chart on Page 27, and call the
service engineer
1.4 User Responsibility
In addition to the routine testing described on routine test, the user has
a responsibility for ensuring certain actions are taken following a fire or
fault, and for implementing remedial action following a specified
incidence of false alarms As a minimum, the user shall record any
incident and inform the service organization, who may be required to
retest the system The user's responsibilities are described fully in IS
2189: 1999

1.5 Routine Testing
In order to ensure that the system is fully operational, and to comply
with the requirements of IS 2189: 1999, the following routine attention is
recommended:
Daily - Check the panel to ascertain that it indicates normal
operation If any fault is indicated check that it has been recorded
and that the appropriate actions have been taken, e g informing the
maintaining company
Weekly - Test at least one detector or call point to confirm the
operation of the panel and the audible alarms Test a different zone
each week and, if possible, a different device Keep a record of the
device and zone tested each week Record and report any
malfunction
Quarterly - The responsible person should ensure that every three
months the system is checked by a competent person Check the
standby batteries and the charger voltage Test at least one device in
each zone to check the panel functions Check the operation of the
audible alarms and any link to a remote manned centre, Central
Station, etc Carry out a visual inspection of the installation to check
for alterations or obstructions and issue a certificate of testing
Annually - The responsible person should ensure that, in addition to
the quarterly checks, each device on the system is tested and that a
visual inspection is made of the cable fittings and equipment
Note: The control panel case should be cleaned periodically by
wiping with a soft, damp cloth Do not use any solvents
