How the System Works

Any Readykey access control system consists of three
components: readers, door controllers and an
administration system.
The readers will detect the unique code in a key and
pass it directly to the door controller. The door
controller compares the code to the information
stored in its memory and, if the key is valid, will
operate the lock and send a report to the
administration system. The administration system is
the means by which the user programs the system
(who is allowed where and when, etc.) and also
where events are reported.

Readers

A reader is a device, usually mounted close to the
door, that detects the unique code in a key or card
and passes it to the door controller where the access
decision is made. There are several types of reader
suitable for different purposes and environments.
Below are some of the special types of reading
devices.
Request to Exit Switch
Sometimes a reader is used on both sides of a door,
controlling both entry and exit from an area.
Normally, however, a Request to Exit motion or
button is used to open a door from the secure side.
This switch, mounted close to the door, when pressed
sends a signal to the door controller to release the
lock. Of course, anyone can press the switch to open
the door when leaving, therefore no identity of the
person can be recorded.

Door Controllers

The door controller is the heart of the access control
system; its main functions are to:
Decide whether a person has access at a
particular door and at a particular time.
Provide power to operate the lock.
Monitor doors for unauthorized access or left
open conditions.

System Overview
In the case of the Readykey K2200 and Readykey
K1200, the administration system is built in to the
door controller and uses the keypad, display and
reader on the front panel. As an option a printer can
be connected to the system that reports events as
they happen, and can also produce listings of
personnel, system setup, past events, etc.
