cardholder to gain entry to the protected area or premises

Access Group – A list of areas to which a cardholder is allowed access. Access may

be restricted to certain times by the use of a Time Schedule

Access Point – A Reader, usually at a point of entry or exit (door, gate, barrier,

turnstile) where access is controlled (and monitored) by an access control system.

Points of entry or exit which are used for anti-passback or roll call require two

Readers and therefore two access points

by the access control software

having been used in the opposite direction. Requires IN and OUT Readers

Archive – A copy of the access control database kept for security against loss of

data

or tag

Card Number – One of the numbers programmed into the card. The card number

is linked to the cardholder in the cardholder record

Card Technology – The physical method by which numbers are stored within

cards

Card Transaction – The act of reading data from a card and passing it to the access

control system

Cardholder – A person to whom a card has been issued. (Also known as user)

Cardholder Record – One of a number of records in the access control database,

each of which links a cardholder’s name to the card number and an access group.

(Can also contain other data such as PIN and personal details)

Cardreader – Equipment that reads data from a card (and PINpad if fitted) and

transmits it to a controller. May include indicator lights

Clamshell – A card that is manufactured by the welding of two outer protective

casings

Clock & Data – Industry standard Reader interface

Codelock – Digital compact keypad, allowing entrance via the use of allocated

PIN codes

Command – An order or instruction that the operator gives to the system, usually

at the computer keyboard.

Also an instruction sent by a computer to a controller. The transmission of messages

between devices

Common Code – A single PIN code that is allocated to all users

Computer – The device which runs the access control software and thereby

maintains the access control database, sends commands and data, receives and

logs system messages, and generates reports

Configuration – The relationship of system components to each other

Controller – A device which polls Readers, makes access decisions and sends

messages to the computer. May also handle other inputs and outputs

Database – (See access control database)

DDA – Disability Discrimination Act. Government legislation forbidding discrimination

of the disabled

Default – A standard condition or value determined by the system unless changed

by operator intervention

Device – Any piece of equipment connected to a system

Dial-up Telephone Line – A normal telephone line which is used by a computer to

communicate with controllers at remote sites via modems, and vice versa

Door – The physical means of controlling access through an access point. Includes

barriers, gates, turnstiles

Door Contact – Door monitoring switch which changes state when a door is

opened or closed

Door Controller – A controller which is directly connected to the Segment

Controller (see Segment Controller) and the Reader. Also contains connections for

the Door Release (see Door Release), Egress Button (see Egress Button) or Break

Glass Unit (see Break Glass Unit)

Door Forced Alarm – An alarm that is activated when a door is opened without a

valid access request or the door exit control being used

Door Release – An electro-mechanical device used to lock or unlock a door

Door Monitoring Switch – Switch which changes state when a door is opened or

closed

Door Open Alarm – An alarm that is activated when a door remains open longer

than a specified time

Duress Alarm – An alarm that is covertly activated by entering a special PIN at an

access point, the cardholder being granted access as normal so as not to arouse

suspicion

Egress Button or Switch – A means of unlocking a controlled door from the secure

side without a valid access request. Also referred to as door exit control

Entro – PC based Access Control software. Used for programming, editing and

reporting of data and events

Event – Any system activity which takes place following a specified occurrence
