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.


4/12

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.


5/12

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.


7/12

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.


9/12

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.


11/12

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.
