ABSTRACT
Automatic Smoke and Burglar alarm
systems are intended to notify the building occupants to evacuate in the event
of a fire , Call, and send Telephone messages to report the event to an off-premises
location in. order to summon emergency services, and to prepare the structure
and associated systems to control the spread of fire. A key aspect of fire
protection is to identify a developing fire emergency in a timely manner, and
to alert the building’s occupants and fire emergency organizations.

1.1 INTRODUCTION
A
Security Alarm is a system designed to detect intrusion-unauthorized entry-into
a building or area. Security alarms are used in residential, commercial,
industrial, and military properties for protection against burglary (theft) or
property damage, as well as personal protection against intruders. Car alarms
likewise protect vehicles and their contents. Prisons also use security systems
for control of inmates, Also fire alarm systems having hard wire layout and
normally opened warning devices like heat detector and smoke detector.
Some
alarm systems {2J serve a single purpose of burglary protection; combination
systems provide both fire and intrusion protection. Intrusion alarm systems may
also be combined with closed-circuit television surveillance systems to
automatically record the activities of intruders, and may interface to access
control systems for electrically locked doors. Systems range from small,
self-contained noisemakers, to complicated, multi-area systems with computer monitoring
and control.
There
this Project Focus on the combination of Smoke Detection in the early stage of
Fire and Burglar protection should there be any intruder with the help of G-SM
Dialer to notify the house/office management in advent of either case which is
achieved through connection between warning devices and personal computer are
dealt with microcontroller we Automatic Smoke and Burglar alarm systems are
intended to notify the building occupants to evacuate in the event of fire or
other emergency, report the event to an off-premises location in order to
summon emergency services, and to prepare the structure and associated systems
to control the spared of fire A key of fire protection is identifying a
developing fire emergency in timely manner, and to alert the building’s
occupant and fire emergency organizations.
1.2 PROJECT OBJECTIVES

Detect smoke before fire outbreak
b.
Detect any form of unauthorized
Intrusion into an area
c. Sound

d. Dial
pre-assigned Telephone numbers to alert the situation i.e. occupant of the area
whether far or near, Fire lighter and the neighbouring Security office (Police
Station, Vigilante, etc.)

ALARM SYSTEM GENERAL OVERVIEW
The
most basic alarm consists of one or more sensors to detect intruders, and an
alerting device to indicate the intrusion. However, a typical premises security
alarm employs the following components:
Premises
control unit (PCU), or panel: The brain” of the system, it reads sensor inputs,
tracks arm/disarm status, and signals intrusions. In modern systems, this is
typically one or niore computer circuit boards inside a metal enclosure, along
with a power supply.
1.3.1 SENSORS:
Devices which detect intrusions. Sensors maybe placed at the perimeter of the
protected area, within it, or both. Sensors can detect intruders by a variety
of methods, such as monitoring doors and windows for opening, or by monitoring
unoccupied interiors for motions, sound, vibration, or other disturbances.
1.3.2 ALERTING DEVICES:
These indicate an alarm condition. Most commonly, these are bells, sirens, and/or
flashing lights. Alerting devices serve the dual purposes of warning occupants
of intrusion, and potentially scaring off burglars.
1.3.3
KEYPADS: Small devices, typically wail-mounted, which function
as the human-machine interface to the system. In addition to buttons, keypads
typically feature indicator lights, a small mulch-character display, or both.
Interconnections
between components. This may consist of direct wiring to the control unit, or
wireless links with local power supplies.
1.3.4 SECURITY DEVICES:
Devices to detect thieves such as spotlights, cameras & lasers.
In
addition to the system itself, security alarms are often coupled with a
monitoring service. In the event of an alarm, the premises control unit
contacts a central monitoring station. Operators at the station see the signal
and take appropriate action, such as contacting property owners, notifying
police, or dispatching private security forces. Such signals may be transmitted
via dedicated alarm circuits, telephone lines, or Internet.
