Some features described in this manual are available depending on the
firmware version of your controller. For details, refer to the CK721-A Software
Release Notes.
KEY TERMS
NOTE: Throughout this manual, the S300-DIN modules and the S300 modules
are also referred to by their short name version. Refer to S300-DIN Modules on
page 1-7 for details.
The following terms are used throughout this manual:
Access Control System (ACS) – In general terms, an access control system
controls access to a location or a resource. When used in conjunction with a
P2000 integration, the access control system includes the P2000 Server and the
CK721-A devices.
Advanced Encryption Standard (AES) – Encryption standard adopted by the
U.S. government in 2002; it supersedes DES. AES uses a symmetrical key
algorithm.
Cardholder – An individual that has rights in the security system. The
individual typically possesses a badge (for example, an ID card) that is used to
gain access to physical areas of a facility.
CHUID – Cardholder Unique Identifier.
CK721-A System – This is a general term that refers to a combination of
CK721-A terminals and expansion enclosures that communicate with the
P2000 system.
CK721-A – The CK721-A contains:
• A 10/100Base-T Network Interface
• A Hitachi SH-4 processor
• System memory for storing cardholder records, system parameters, and
history
• A serial connection for communication with the user interface
• An RS-485 connector for communication to the modules
DCS – Destination Selection Control Terminal.

CK721-A Installation and Operation Introduction
24-10025-121 Rev. A
1-3
Encryption – The process of changing data into a form that can be read only
by the intended receiver. To decrypt the message, the receiver of the encrypted
data must have the proper decryption key (generally protected by a strong
password). P2000 v3.11 encryption is implemented using the FIPS 140-2,
validated, certificate number 1336, cryptographic module, from Microsoft
(www.microsoft.com). CK721-A encryption is implemented using the FIPS
140-2, validated, certificate number 1051, cryptographic module, version 1.2.3,
from the Open Source Software Institute (www.oss-institute.org).
Expansion Enclosure – An expansion enclosure contains only a power supply,
a tamper switch and a power indicator. The indicator can be seen when the
cabinet door is closed.
External Device – This general term applies to any device that is wired to the
CK721-A system, such as a reader or input device. A motion sensor is one type
of input device.
FASC-N – Federal Agency Smart Credential Number.
FICAM – Federal Identity Credential and Access Management.
File Transfer Protocol (FTP) – A standard network protocol used to transfer
files from one host to another over a TCP-based network.
GUID – Global Unique Identifier.
IPv4 – Internet Protocol version 4.
IPv6 – Internet Protocol version 6.
LCS – Lift Control System (from ThyssenKrupp).
Modules – The modules provide additional reader interfaces, input points, or
output relays to the CK721-A system. Modules can be installed in the S300
expansion enclosures; RDR2S, RDR2S-A, I8O4, RDR8S, and I32O16 modules
can be installed in the S300-DIN enclosures.
OTIS EMS – OTIS (High Level Interface) Elevator Management System,
serial.
PACS – Physical Access Control System.
PAM – HID pivCLASS Authentication Module.
Panel – This generic term refers to an enclosure with the CK721-A and power
supply installed. The panel contains a tamper switch, a power indicator light,
and an optional battery backup.
PIN – Personal Identification Number.

CK721-A Installation and Operation Introduction
24-10025-121 Rev. A
1-4
PIV – Personal Identity Verification.
PIV-I – Personal Identity Verification - Interoperable.
Secure FTP (SFTP) – A program that uses SSH to transfer files. Unlike
standard FTP, it encrypts both commands and data, preventing passwords and
sensitive information from being transmitted in the clear over the network. It is
functionally similar to FTP, but because it uses a different protocol, you can't
use a standard FTP client to talk to an SFTP server, nor can you connect to an
FTP server with a client that supports only SFTP.
Secure Shell (SSH) – A network protocol that allows data to be exchanged
using a secure channel between two networked devices.
Telnet – A network protocol used on the Internet or local area networks to
provide a bidirectional interactive text-oriented communications facility using
a virtual terminal connection.
ThyssenKrupp Serial Elevator – ThyssenKrupp High Level Interface
Elevator Access Control, serial.
User Interface – The CK721-A User Interface provides access to the CK721-
A panel configuration graphical user interface (GUI) via a serial connection to
a laptop (or other computer) running common terminal emulation software or
via a Telnet/SSH/SFTP network connection.
UUID – Universal Unique Identifier.
UNPACKING THE EQUIPMENT
Carefully inspect the shipping containers as soon as you receive them (with the
delivery agent present). Some shipping companies want to have an agent
present when a damaged container is opened. If a container is damaged, open it
immediately, inspect the contents, and have the agent make note on the
shipping document. Check the purchase order against the packing slips to
ensure the order is complete.
If the contents of a container are damaged in any way, notify the carrier and
your Johnson Controls® representative immediately. Report any discrepancies
to your Johnson Controls representative. Save the packing materials for
possible return shipments.

GENERAL DESCRIPTION
All CK721-A panels are connected via a 10/100Base-T Ethernet network to the
P2000 system. The CK721-A is intended to be mounted in an S300-DIN
enclosure (large or small). Each model has a total capacity 200,000 cards and a
8000 off-line transaction base memory.
NOTE: When the number of badges exceeds 120,000, the number of access
groups should be limited to 50,000.
CK721-A panels are connected via standard 10/100Base-T cabling and 10/
100Base-T hubs. The CK721-A is programmed and monitored via the P2000.
The CK721-A provides its own user interface through the serial connection
located on the CK721-A. This interface facilitates the initial setup, as well as
commissioning and troubleshooting.
The CK721-A is an advanced, intelligent controller. You can add modules to
connect readers, monitor 2 or 4-state input points, and add output relays to
perform manual or automatic control functions. In addition, input points can be
linked to output relays. Communication between the CK721-A and the
modules is accomplished via RS-485 per Cardkey implementation.
The CK721-A uses the following modules:
•RDR2S-A
• I8O4
•RDR8S
• I32O16
CK721-A MODULE
