Introduction
CRC Technical Reference Manual 1.3
Introduction to the CRC
The Card Reader Controller (CRC) is shown in Figure 1-1. The
CRC interfaces card readers and door locks to an integrated
system (fire, security, and access control) allowing access to a
protected area only when a cardholder presents a valid access
card, and has access privileges for that area. The intelligence for
controlling access is programmed into the CRC.
Figure 1-1: Card Reader Controller
CRCs are connected by a dedicated RS-485 circuit, called a
SAC bus. The SAC bus allows the CRC to communicate with a
control panel. The control panel can support an integrated
security, access control, and fire alarm system.
Model CRCXM is a version of the CRC with expanded memory
capacity. It has the same physical and functional attributes as the
CRC, but can store a larger database of cardholder and history
records.
For specifications please refer to the installation sheet CRC
CRCXM Card Reader Controller, P/N 387625.

Introduction
1.4 CRC Technical Reference Manual
Physical description
The CRC has a streamlined white housing, designed to blend in
with most surroundings. This lets you install the CRC in plain
sight, which typically requires much less time and effort.
The CRC has terminals for connection to the SAC bus, power,
card reading devices, and door locking mechanism. Space is
provided for a standby battery. The CRC battery continues to
operate the CRC in case of a power failure. Jumpers are
provided for configuring the CRC to use ac or dc power, and to
operate continuous or intermittent operation door locks.

Introduction
CRC Technical Reference Manual 1.5
Overview of operation
Each door being used for access control requires a CRC, a card
reading device, and an electric door lock. Both the card reader
and door lock are wired to the CRC.
An access card is assigned to each person that requires access.
The access card is equipped with a unique code that must be
entered into the database of the CRC. The unique code allows
the CRC to recognize a valid cardholder.
Each cardholder is assigned a set of access privileges that
determine the times and conditions under which access is
granted. The set of privileges is called an access level
When a card is read at the card reader, the following sequence of
events occurs before the person is granted access:
1. The reader interprets the code on the card and forwards this
data to the CRC.
2. The CRC determines whether to grant access. Some of the
questions that must be satisfied to make this decision are:
• Does the card code exist in the CRC database?
• Does the cardholder have disarm privileges for the
security partition assigned to the CRC?
• Is the security partition armed in the area being
accessed?
• Is the time of day within the access level schedule?
• Does the person have an irregular access privilege?
3. If the CRC determines that the person has the correct access
privileges, it releases the door lock, thereby allowing the
person to open the door.
4. The CRC automatically shares entry and exit event
information when there are multiple CRCs within a
partition.
5. Entry and exit event information required by external
integrated gateway connections (such as FireWorks) is
automatically sent to the control panel.

2.2 CRC Technical Reference Manual
CRC features
System integration
The CRC integrates seamlessly with the EST3 fire alarm system.
If a fire alarm occurs, a simple program rule can unlock exit
doors. With fire and security devices installed on the same
network, no degradation in system performance occurs.
Because each CRC makes its own access decisions, very little
network traffic is generated by the access control function. This,
along with the integrated design of the network operating
system, ensures that fire signals always receive the highest
priority. To reduce traffic even further, the SDU optimizes
which event messages the system receives.
Enhanced survivability
In performing its task, the CRC maintains a database of up to
8,000 users with all options and schedules. It also stores the
5,000 most recent access denied (and optionally, access granted)
events.
The CRCXM stores up to 36,000 users and 20,000 events.
If the control panel 3-CPU1 or 3-SAC fails, or if the CRC loses
communication with the 3-SAC, the CRC continues to function
without any degradation.
If power is lost to the CRC, it can continue to operate on its own
internal battery power. The CRC will continue to grant and deny
access for a limited amount of time (refer to battery calculations
in Appendix A), thereby eliminating the need for granting free
access during a degraded period.
When battery power is exhausted the control panel generates a
communication fault event message for the CRC.
System CRC capacity
In an integrated system, security and access control devices are
connected by a dedicated RS-485 circuit, called a SAC bus. The
SAC bus originates at the Security Access Control module
(3-SAC).
Each 3-SAC can support up to 62 CRC or KPDISP (Keypad
Display) devices for Class B wiring (30 CRCs or KPDISPs for
Class A). This is a multiple-drop circuit and does not require a
dedicated run for each device.

Features and functions
CRC Technical Reference Manual 2.3
Should network communication be lost, the CRC will continue
to grant access based on the database stored in its memory,
without loss of any security feature.
(Applications that rely on communication between CRCs are the
exception. For example, anti-passback and two-person rule
applications, requiring more than one door, may not work in
degraded mode.)
Controls for readers and locks
Each CRC provides the power and electronics required to
control and monitor a single door. The CRC can accommodate
two card readers (entry and exit) plus an associated electric door
lock. The CRC can use an external 24 Vdc power supply or a
CRCXF CRC Transformer (a 16.5 Vac transformer) to power
continuous-duty locks.
If desired, all entry and exit events can be reported to the
FireWorks Guard Workstation. It is also possible to determine
the current location of an individual and obtain a list of all
people who are in the premises.
The CRC can monitor the door contact and activate an optional
sounder if the door is opened without first badging out. This can
act as a reminder to badge out, and ensure that management
knows who is in the building. It can also act as a simple form of
exit control in the event of an unauthorized exit.
LED and CRC sounder drivers
The CRC provides LED driver terminals for the card readers.
Thus, the readers can visually indicate whether access is granted
or denied.
The CRC provides different LED flash rates for applications that
require a PIN number or a second card. Examples: two-person
rule or escorted visitor.
A driver for an audible sounder is also provided by the CRC.
Refer to the installation sheet for the CRCSND CRC Sounder,
P/N 3100033 for additional information.
CRC dry contact relay connections
The CRC includes common, N.O., and N.C. outputs from a
Form C relay. These can be used to control auxiliary fire alarm
devices such as fans and dampers, as well as devices that
support handicap functions

Features and functions
2.4 CRC Technical Reference Manual
CRC input circuits
Each CRC has two input circuits for use with access control and
security devices. These are typically used for a door position
sensor and a request to exit device. The input circuits can be
configured for use with a switch, controlled by a receptionist,
that manually unlocks the door. Finally, the input circuits can be
used as security input points.
Access cards
The CRC is compatible with a large variety of access cards.
These cards do not require a specially-ordered facility code. EST
offers access cards that are prenumbered and ready for use. The
EST cards have nonrepeating, unique numbers. This makes it
easy for administrators to add new cards to the access control
system.
When a site has an existing access control system, the CRC is
flexible enough to integrate with most cards and card readers
already in use. To determine which cards and card readers are
compatible with the CRC see Chapter 3, Hardware and
Equipment.
Card readers
The CRC is compatible with a variety of card readers that
communicate using the Security Industry Association (SIA)
Wiegand output format. These include:
• Proximity
• Wiegand pin
• Magnetic stripe
• Smart card
• Keypad
To determine which cards and card readers are compatible with
the CRC, see the CRC installation sheet.
Database storage
Each CRC stores a complete database within its memory. It
retains all the data necessary for complete operation of the
devices it controls. This distribution of intelligence maximizes
the speed at which access decisions are made and provides
survivability in the event that the CRC is disconnected from the
network.
Cardholder data is created and maintained by the Access Control
Database (ACDB) program, which runs on the end user’s PC.
Technical Manuals Online! - http://www.tech-man.com
firealarmresources.com

Features and functions
CRC Technical Reference Manual 2.5
This information is encrypted and sent to the CRCs, via either
direct connection or modem (dial-up) connection.
With modem connection, the ACDB program can dial up the
system and send the encrypted database information to
individual CRCs. This allows a single access control database to
serve multiple sites.
Modem connection also permits multiple tenants to share a
common access control system without sharing a common
database.
Access levels and schedules
An access level is a predefined collection of access and security
privileges. One or more cardholders can be assigned the same
access level, and thus would have the same set of privileges.
Access levels consist of a list of doors, each with a specified
schedule. Any combination of doors and schedules can be
assigned to an access level. The access level determines whether
or not a cardholder can access a given door at a given time.
Each cardholder can be assigned two access levels. This helps
the administrator quickly assign multiple access rights to a
single person. For example, a female manger could be assigned
two access levels, one access level for mangers and one access
level for females. This grants the employee access privileges for
the manger-level doors and for all women’s restrooms.
Each access level can have an active date and an expiration date.
This means the two access levels can be used to control rotating
shifts, parking lots, or temporary schedules.
When used for rotating time shifts, the first access level is the
current schedule and the second access level the future schedule.
The first expire date and the second active date reflect the date
of the change of shift.
In parking lots, dual access levels allows for canceling parking
privileges without canceling building access.
In temporary schedule use, the second schedule overrides the
first schedule when active and returns control to the first
schedule when it expires.
Schedules and holidays
The CRC stores the schedules and holidays created in the ACDB
program. Each schedule identifies specific times (in 15-minute
increments) and days when access is granted.
Technical Manuals Online! - http://www.tech-man.com
firealarmresources.com

Features and functions
2.6 CRC Technical Reference Manual
Holidays are exceptions to normal Monday through Sunday
schedules, when different access requirements are desired. Many
holidays can be programmed using rules rather than fixed dates.
This minimizes year-to-year programming required to update
holidays.
For example, schedules for fixed holidays such as January 1,
which can fall on a Saturday or Sunday, are assigned to take
place on the previous Friday or next Monday respectively.
Database capacities
All access decisions are made locally in the CRC. The CRC’s
non-volatile memory holds the cardholder, schedule, and holiday
information required.
A total of 8,000 cardholders can be stored in each CRC. The
CRCXM has additional memory, and supports 36,000
cardholders.
The CRC or CRCXM can store 1,200 access levels (255 per
company). Each cardholder can be assigned two access levels.
The CRC or CRCXM can store 1,200 schedules (255 per
company) and 1,200 holidays (255 per company).
The CRC stores up to 5,000 events per door, ensuring no loss of
history. The CRCXM has additional memory and stores up to
20,000 events. This history information can be uploaded to the
ACDB program on demand, for use in a variety of reports.
User-defined logged attempts
By using a suppression schedule in the ACDB, you can
determine when normal access events are to be logged. Logged
events always include irregular events and unsuccessful
attempts. Determining what you want to be logged helps
eliminate unnecessary events from entering the history buffer.
User-defined PIN schedule
A schedule can be used to define when a PIN must be entered to
verify each card swipe. To use this option, a combination card
reader and keypad must be installed. The use of a PIN decreases
the possibility that a recently lost or stolen card can be used to
gain entry. A schedule defines when a PIN must be used. This
can be during business hours, outside business hours, or at all
times.
The card is always presented first. If the schedule determines
that a PIN is required, the red LED on the card reader will flash

Features and functions
CRC Technical Reference Manual 2.7
at 1 Hz. This is an indication that the user must enter a PIN. The
user then enters the PIN to gain access.
This option is selectable per door. If no schedule is defined for a
door, that door will not require a PIN. For this application the
keypad used must provide output in standard Dorado 8-bit
Wiegand data format.
User-defined unlock and open times
Using the ACDB program, the administrator can control how
much time a person has to enter or exit through a door. The CRC
controls both the unlock time and door open time, and these can
be set in the ACDB program.
Unlock timers control the number of seconds that the door stays
unlocked when a user badges in. When the unlock timer expires
the door lock locks. The ACDB has three unlock timers:
• Standard unlock
• Handicap unlock
• Manual unlock
The CRC relay can be used to control a door opener. Door open
timers control the number of seconds that the relay stays active.
The ACDB has two door open timers:
• Manual open time
• Relay open time
Refer to Chapter 6: Programming for more information on these
fields.

Features and functions
2.8 CRC Technical Reference Manual
CRC functions
Construction mode
The CRC can operate in a construction mode. In this mode, the
building contractors use specially coded cards for gaining access
before the system is fully operational.
This mode is in effect before the CRC is programmed by the
ACDB. As soon as a card record is downloaded into the CRC,
the construction card stops working.
Remember that temporary cards can be included in the access
control database and downloaded into the CRC. This allows
workmen to continue installation and testing, even after the
ACDB database has been downloaded. The ACDB user can
define an automatic deactivation date for such cards.
The ACDB cannot be used to restore a CRC to its original
condition. This can only be done with the SDU, using the
Remove from 3-SAC download action (found in the
Communication Functions dialog box).
Security partition disarming
A partition is an area of an alarm system that can operate and be
controlled independently. A CRC can be used to disarm one of
255 security partitions.
Alarm point bypass
CRCs can be programmed to automatically bypass alarm points
when a cardholder is granted access. For example, an employee
entrance door may need to be armed at all times. Bypassing this
door contact allows free entry and exit as authorized employees
come and go. If an unauthorized entry is made an annunciation
alarm sounds.
Cardholder disability
A special disability option allows an individual additional access
time. A disability option can be selected for any cardholder.
When such a cardholder presents his card to the reader, the CRC
recognizes the option and provides additional, user-defined
access time and operates a relay that can activate an automatic
door opener.
