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 the current edition of the National Fire Protection
Association Standard 72 (NFPA 72), manufacturer's recommendations,
State and local codes, and the recommendations contained in the
Guide for Proper Use
of System Smoke Detectors, which is made available at no charge to
all installing dealers. A study by the Federal Emergency Management
Agency (an agency of the United States government) indicated that
smoke detectors may not go off in as many as 35% of all fires. 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.

RE / DD / UM / 2508 V1.2- 01

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 photoelectronic 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 devices such as 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 properly
maintained and replaced regularly.
Equipment used in the system may not be technically compatible with
the control. 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 per the manufacturer's
recommendations, and UL and NFPA standards. At a minimum, the
requirements of NFPA 72 shall be followed. 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 NFPA – 72, 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.
To Evacuate the premises:
Press the Evacuate key and enter the password to OPERATE NAC’s
(Sounders).
Fault Indication:
If the control panel indicates a Fault condition, make a note of all
illuminated indicators and proceed as described in chapter 6 (Section
6.4) or call 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.

RE / DD / UM / 2508 V1.2- 01
11
1.5 Routine Testing
In order to ensure that the system is fully operational, and to comply
with the requirements of UL864 Standard & NFPA – 72, 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 the
appropriate actions have been taken e.g. informing to 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 cabinet should be cleaned periodically by
wiping with a soft, damp cloth. Do not use any solvents.
