A fire alarm
control panel
(FACP), or fire
alarm control
unit (FACU), is
an electric
panel that is
the controlling
component of a
fire alarm
system. The
panel receives
information from
environmental
sensors designed
to detect
changes
associated with
fire, monitors
their
operational
integrity and
provides for
automatic
control of
equipment, and
transmission of
information
necessary to
prepare the
facility for
fire based on a
predetermined
sequence. The
panel may also
supply
electrical
energy to
operate any
associated
sensor, control,
transmitter, or
relay. There are
four basic types
of panels: coded
panels,
conventional
panels,
addressable
panels, and
multiplex
systems. A fire
alarm control
panel is
required under
the building
code for a
majority of new
commercial
building
construction in
most countries.
Conventional Fire Alarm Systems, in their various forms, have been around for
many years and have changed little in that time in terms of technology; although
design and reliability have improved significantly. However, Conventional
Systems are a well-proven technology protecting many hundreds of thousands of
properties worldwide. A Conventional Fire Alarm System is often the natural
choice for smaller systems or where budget constraints exist.
A fire
extinguisher is
an active fire
protection
device used to
extinguish or
control small
fires, often in
emergency
situations. It
is not intended
for use on an
out-of-control
fire, such as
one which has
reached the
ceiling,
endangers the
user (i.e. no
escape route,
smoke, explosion
hazard, etc.),
or otherwise
requires the
expertise of a
fire department.
Typically, a
fire
extinguisher
consists of a
hand-held
cylindrical
pressure vessel
containing an
agent which can
be discharged to
extinguish a
fire
A heat detector
is a device that
responds to
changes in
ambient
temperature.
Typically, if
the ambient
temperature
rises above a
predetermined
threshold an
alarm signal is
triggered. In
the case of
sprinkler
systems, water
will be released
to extinguish
the fire. Heat
detectors can
also be further
broken down into
two main
classifications
of activation,
"rate-of-rise"
and "fixed." The
most
sophisticated
units are
activated by
both conditions.
Conventional
Photoelectric
Smoke Detector
and Smoke cum
Heat Detector
All of Agni
AD333 series
detectors meet
the requirements
of UL 268 and EN
54-7/5 for use
in Fire Alarm
signaling
systems. They
are intended for
use in 2-wire/4
wire Class A or
B supervised
zone circuits.
The AD 333
Series detectors
are subject to
panel
compatibility
limits and
compliance with
corresponding
NFPA 72E
standards, local
codes, and
ordinances.
AD-333 series
include 2-wire
and 4-wire
detectors, which
provide fast and
reliable
response to
photoelectric
smoke and heat
(1350F)
detection. While
the smoke and
heat detection
circuits operate
independently,
their outputs
being "OR"
connected. The
detector provide
the fire
detection
A smoke detector
is a device that
detects smoke.
Commercial,
industrial, and
mass residential
devices issue a
signal to a fire
alarm system,
while household
detectors, known
as smoke alarms,
generally issue
a local audible
and/or visual
alarm from the
detector itself.
A fire alarm
pull station is
an active fire
protection
device, usually
wall-mounted,
that, when
activated,
initiates an
alarm on a fire
alarm system. In
its simplest
form, the user
activates the
alarm by pulling
the handle down,
which completes
a circuit and
locks the handle
in the activated
position,
sending an alarm
to the fire
alarm control
panel. After
operation, fire
alarm pull
stations must be
restored to the
ready position
using a special
tool or key in
order to
deactivate the
alarm sequence
and return the
system to
normal.
Primitive manual
stations
requiring only a
single action or
hand motion to
activate, can be
subject to
unwanted
activation by
jarring or
accidental
contact. Early
strategies to
cope with this
problem included
requiring the
operator to
break a pane of
glass to release
an internal
spring operated
mechanism.
Manual pull
stations that
require two hand
motions such as;
lift up and pull
down or push in
and pull down
have since
replaced the
break glass and
single action
models in many
modern
installations
fire alarm
sounders from
Klaxon Signals
have been
designed to
provide
effective
warning,
ensuring the
safety of people
they are
intended to
protect. The
range of fire
alarm sounders
incorporates
Sonos sounders
for small to
medium
commercial
applications and
Nexus sounders
for high out put
industrial
application
Electronic
equipment
containing
transistors, and
particularly
equipment
containing
integrated
circuits (e.g.,
personal
computers,
television
receivers,
videotape
recorders), are
vulnerable to
damage by
transient
overvoltages
(also called
"surges") on the
ac supply mains.
In the absence
of a surge
suppressor, such
transient
overvoltages may
have peak
voltages as high
as 6000 V, which
can destroy
transistors,
integrated
circuits, and
other electronic
components.
These transient
overvoltages are
commonly caused
by lightning and
switching
reactive loads
on the ac supply
mains. As a
result of the
threat and
vulnerability,
it is good
engineering
practice to plug
every personal
computer or
other electronic
system into a
surge
suppressor.
Fire Hose Reels
are located to
provide a
reasonably
accessible and
controlled
supply of water
to combat a
potential fire
risk. The length
of a fully
extended fire
hose is 36
meters with a
diameter of 19mm
(Outside
Diameter). These
appliances are
designed to
deliver, as a
minimum,
0.33ltrs of
water per
second. A
control nozzle
attached to the
end of the hose
enables the
operator to
control the
direction and
flow of water to
the fire.
Sprinkler
Irrigation is a
method of
applying
irrigation water
which is similar
to rainfall.
Water is
distributed
through a system
of pipes usually
by pumping. It
is then sprayed
into the air and
irrigated entire
soil surface
through spray
heads so that it
breaks up into
small water
drops which fall
to the ground.
Sprinklers
provide
efficient
coverage for
small to large
areas and are
suitable for use
on all types of
properties. It
is also
adaptable to
nearly all
irrigable soils
since sprinklers
are available in
a wide range of
discharge
capacity. Jain
Sprinkler system
is an unique
irrigation
system. It is
designed to
ensure maximum
water saving,
combining high
quality,
affordability
and ease of
installation.
