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

6/28/2011 DOC.NO.: 150D - 1 P/N RE 150D Rev. No. 1

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

Local Buzzer
A piezo buzzer provides separate and distinct sounds for
alarm and trouble conditions:
 Alarm – steady
 Fault – pulse 0 5sec ON and 0 5sec OFF
2.3.2 Controls
SELECT, TEST and ISOLATE Keys: The SELECT is used to select any
particular zone for isolation or for test When it is pressed, zone 1
will be selected first with the identification of ISOLATE LED
blinking; consecutive SELECT key presses can change the zone
selection to 2 The particular zone can be isolated by pressing
ISOLATE key or tested by pressing TEST key
When pressing the ISOLATE by selecting the zone, the
previous status of isolate LED will be interchanged, i e it may go
from ON to OFF or OFF to ON The ON status indicates that the
zone has been isolated By the time, no voltage will be there in
the isolated zone loop And the OFF status indicates that the
zone has been normalized
After the selection of particular zone, if the TEST key is
pressed, that particular selected zone is tested with buzzer
sound
Note:
a. We strongly recommend to avoid isolating any particular
zone unless it is essential for maintenance purpose.
b. For zone isolation and their normalization, use IS LATE key.
ACK Key: During fire/fault condition, ACK key is used to silence
the external Sounders (NAC) and the internal buzzer tone
RESET Key: This key is pressed to reset the entire system and
While in reset condition, all detector loop voltages are cut off
up to 3 seconds for Detectors and MCPs, Then voltages are put
on to the loop
Note: The zone loop voltage will cut off only in fire
condition during reset.

Verify that wire sizes are adequate for all initiating and Indicating
device loops Most devices cannot tolerate more than a 10% I R drop
from the specified device voltage
Adherence to the following will aid in problem-free
installation with long-term reliability:
Like all solid-state electronic de ices, this system may operate
erratically or can be damaged when subjected to lightning-induced
transients Although no system is completely immune from lightning
transients and interferences, proper grounding will reduce
susceptibility verhead or outside aerial wiring is not recommended,
due to an increased susceptibility to nearby lightning strikes. Consult
with the Technical Services Department if any problems are
anticipated or encountered
Disconnect AC power and batteries prior to removing or inserting
circuit boards Failure to do so can damage circuits
Remo e all electronic assemblies prior to any drilling, filing, reaming,
or punching of the enclosure When possible, make all cable entries
from the sides or rear Before making modifications, verify that they will
not interfere with battery, transformer, and printed circuit board
location
Do not tighten screw terminals more than 9 in-lbs
Over-tightening may damage threads, resulting in reduced terminal
contact pressure and difficulty with screw terminal removal
Though designed to last many years, system components
can fail at any time This system contains static-sensitive
components Always ground yourself with a proper wrist strap before
handling any circuits so that static charges are removed from the
body Use static-suppressive packaging to protect electronic
assemblies removed from the unit
Follow the instructions in the installation, operating, and programming
manuals These instructions must be followed to avoid damage to the
control panel and associated equipment FACP operation and
reliability depend upon proper installation by authorized personnel
