What is a SYSTEM?
System is a set of interacting or
interdependent entities forming an
integrated whole.
A system is a collection of parts that
interact with each other to function as
a whole.

Characteristic of a System
Objective
Every system has a predefined goal
or objective towards which it works.
For example: an organization would
have an objective of earning
maximum possible revenues, for
which each department and each
individual has to work in coordination.

Standards
It is the acceptable level of
performance for any system.
For example take a sorting problem.
There are various sorting algorithms.
But each has its own complexity. So
there should be a standard or rule to
use a particular algorithm.

Environment
Every system whether it is natural or
manmade co-exists with an environment.It is very important for a system to adaptitself to its environment.
For example, humans live in a particular
environment. As we move to otherplaces, there are changes in thesurroundings but our body graduallyadapts to the new environment.

Feed Back
Feedback is an important element of
systems.
The output of a system needs to beobserved and feedback from the
output taken.

Boundaries Every system has defined boundaries within which it
operates. Beyond these limits the system has to
interact with the other systems.
Example: Personnel system in an organization has its
work domain with defined procedures. If the financial
details of an employee are required, the system has
to interact with theAccounting system to get the
required details.

Interface
Interfaces are another important
element through which the system
interacts with the outside world.
System interacts with other systems
through its interfaces. Users of the
systems also interact with it through
interfaces.

Most systems share common characteristics
Systems have structure, defined by parts
and their composition
Systems have behavior, which involvesinputs, processing and outputs of
material, energy or information.
Systems have interconnectivity: thevarious parts of a system have functional
as well as structural relationships
between each other.

Some functions of a system
Modular Design, Expandability, Flexibility
Modular hardware and software design providesthe ability to adapt and expand the system tocater for virtually any configuration or applicationrequired - small or large.
Configuration options within the programmingallow Security, Access Control and Building
Automation to exist as separate entities withinthe same system or to be integrated to whateverextent required.
Overall system dimensions can be expandedbeyond the capacity of a single control panelusing powerful system management software.

Integration
The various Concept Module components canbe installed to offer independent Intruder Alarm
or Access Control or Building Automationfunctionality or these functions can be integratedto whatever degree is desired.
All common 'integrated' functionality is
embedded in the system programming simplyrequiring Installers to select an option.
