Think about it, how many different keys do you
have in circulation? And who has a copy of each key?
With multiple keys for every door, it's easy to see
how key control management has become a primary
concern when it comes to life safety and security.
Today, most environments have a mixture of both open
and closed areas, which require different forms of
security – and different forms of secure access. The
development of innovative security solutions is
driven by the performance criteria that higher
levels of security require.
Access control is vital to providing a safe and
secure environment. Restricting access at specific
entry points to authorized people is the basic
definition of access control. Grizzly Security

Basic Principles
The User presents their Card or Token to the Reader.
This information is sent to the Controller. The
Controller then Validates the Card, by checking
Is the Card is Valid on its Card Database.
Is it authorized to open the door (Access Group)
Is the Card authorized during this particular time
period (Time Zone).
Once the criteria of all three are met it then
releases the Lock to allow access through the door,
and the opening of the contact is ignored
The Card number and the Reader number is then sent
to the Computer and found on its database, which is
listed with a Users Name. The Users name, Card
number, Reader, and time it was used is sent to the
"History File" or "Transactions Log", to be stored
and also displayed on the monitor screen.
Should the door be forced open, the contact is
therefore opened without a Valid Card. The
Controller would then send this information to the
Computer indicating "door forced" and generate and
Alarm Condition on the screen and/or a sounder
alarm.
