IMPORTANCE OF SAFETY AND
SECUIRTY IN OUR DAILY LIVES:
• Ensures the well-being of
individuals
• Protection of assets
• Prevents crimes
• Creates a safe environment

1. DEFINING ALARM SYSTEMS
3
1.1. Alarm system is a network of interconnected devices designed to
detect and alert individuals or authorities to specific events or
potential threats.
Alarm systems play a vital role in safeguarding property, lives and
valuable assets, offering a peace of mind and protection in our lives
1.2. These systems are used to enhance security and safety in many
settings such as: homes, businesses, property and public spaces such
as malls or plazas.
They detect events such as break-ins , fires, medical emergencies or
environmental hazards and triggers audible or remote alarms to
prompt a rapid response.

2.1. Examples of alarms:
• Burglar alarms:
• Heat alarms;
• Car alarms;
• Phone alarm;
• Carbon monoxide detector
• Earthquake detector
Types of alarm systems:
• Fire alarm
• Wired alarm
• Wireless alarm
• Monitored and unmonitored alarms

2.2. DIFFERENCES BETWEEN ALARM SYSTEMS
WIRED ALARM SYSTEM
• Uses wires to connect various
components
• Has a central control panel
• Components include: keypad,
sensors, cameras, and sirens
• Requires a power source and a
phone line to operate
Alarm System
FIRE ALARM SYSTEM
• Device or network of devices
that detects and warn people
of a fire or other emergencies
• Can be automatic, semi –
automatic or manual
• Has ability to monitor itself for
any problems

2.2. DIFFERENCES CONTINUED
MONITORED ALARM SYSTEMS
• Connected to a central
monitoring stations [CMS]
• During emergencies it sends a
signal to the CMS
• Includes sensors such as, motion
detectors, smoke detectors
• When triggered, the control panel
informs the CMS then they call
you.
Alarm System
6
UNMONITORED ALARM
SYSTEMS
• Does not have a professional
monitoring service [relies on
owner]
• Includes a control panel, motion
sensors, door and window sensors
• When triggered, it produces local
noises to alert on-site users about
possible danger

3. COMPONENTS OF AN ALARM SYSTEM
SENSORS
• Active ultrasonic sound waves
at a frequency above the
range of human hearing
• Waves bounce off objects in
the immediate vicinity and
return to the sensor
• Transducer within the sensor
acts as a waypoint for the
signal
Alarm System
7
CONTROL PANEL
• Programmed to perform an
automatic shutdown if certain
conditions warrant.
• When activated under
parameters , it will shut down
the equipment in area then
activate the alarm
10/20/2023
COMPONENTS OF ALARM SYSTEMS
SIREN
• Generates a loud, piercing
sound when activated
• It can also be motion activated
using infrared signal
• They can also emit light to
attract attention to the
property
Alarm System
8
INFRARED
• Reacts when there is a change
in temperature in the
parameter.
• They also have pet sensitive
detectors as standard to
ensure you do not get false
alarms

HOW ALARM SYSTEMS WORK
10
4.1.1. PROCESS OF DETECTION
• The detection component of an alarm system is called a sensor.
• Common types of sensors that may be used to protect your home
include motion detectors, door and window contacts, glass break
detectors, and smoke detectors.
• When a sensor detects activity, it sends a signal to the alarm
system control panel, which is the brain of the system.
• The control panel determines if the event poses a threat and then
sends a notification about the event.

4.1.2 RESPONSE
• An Alarm Notification System is a technology designed to monitor the performance
and functionality of crucial networked systems and equipment, alerting appropriate
personnel when issues arise.
• It serves as an early warning system, detecting irregularities and potential problems
before they escalate into major disruptions or failures.
• An alarm panel responds to a triggered alarm by activating physical alarms such as a
siren and/or strobe lights.
• Alarm Management standards define that a necessary attribute for any alarm is its
response procedure. If an alarm does not warrant a response, then it does not have a
purpose and should be removed from the alarm system.
• An example of an alarm response procedure for a fire alarm is to ensure the
immediate safety of anyone within the vicinity of the fire, raise the alarm, phone
security, and evacuate the immediate area.

DEMONSTRATION OF SIMPLE CCTV SYSTEM
12
1. Set up the CCTV system: install the cameras in a strategic locations
2. Set up the alarm: Install the sensors in areas that need to be
monitored
3. Intergrade the CCTV and alarm systems: Connect the alarm to
control panel to the CCTVs systems recordings
4. Test the system: test by simulating an intrusion or triggering an
alarm sensor
