Authentication
Generally speaking, authentication is
verification of the genuineness of a certain
property. Example: Before allowing access to a
computer system, the computer asks for the
correct password for the entered user name. In
access control, devices frequently read data of
a credential and thus check the access
authorizations. Advanced access checks
additionally require entry of a PIN code or
verification of biometric properties (such as
fingerprints).
Blocked (state)
In the blocked status, the actuating element
(e.g. door handle, knob, turning bolt or locking
lever) is either blocked or not coupled, i.e. you
cannot latch or unlatch the door (room door,
locker door, cabinet door).
Bolt (Door)
Mechanical locking element in a door lock.
Used to bolt the door leaf. At least two stable
closing positions of the bolt are differentiated
("Bolted", "Unbolted"). If the bolt engages with
the opening of the strike plate (or the
doorframe), the door leaf is
bolted
. The
closing positions are selected by means of
appropriate closing elements (e.g. keys). "Bolt"
must not be confused with "turning bolt" (bolt
olive).
Credential
Collective term for a medium (such as an
identity card or key tag) that contains the
identification data of a person. Credentials are
frequently assigned to a specific person.
Door closer
A mechanical device for the automatic,
damped closing of a door.
Door element
Door leaf and doorframe. Not to be confused
with "Fitting".
Door initialization card
On a door initialization card, door-specific data
is saved (e.g. door number, door function,
opening hours, time models, date, time,
authorizations) that you have to transmit to the
device. The door initialization card is created in
your access control system.
Door leaf
The moving part of the door element.
Door Leaf: Open
Positions of the door leaf in which neither latch
nor bolt can interlock with the assigned
openings of the locking plate (or door
frame/non-active leaf). The passageway is
free. The cover plate is, for example, only
visible in the status "Open (door status).
Opposite: "Closed (Door Status)".
Door status: Locked
A door, also a full-height turnstile or other
locking device, is locked when passage is not
possible (without booking). See also locking a
door. Opposite: Door status released.
Door status: Unlocked
The bolt is not aligned with the corresponding
opening of the strike plate. The term relates
only to the status of the bolt, not to the status
of the latch. Example: A door leaf with a
mechanical door lock can be unbolted by
turning the key. Opposite: "Locked".
Doorknob
Colloquial: "Door handle" or "Door latch". A
hand-operated lever or knob on the outside of
the door lock. With the door knob, e. g. the
latch can be pulled back manually and (often
for knob use) the bolt can also be moved.
Facility card
A facility card is a card that is assigned to only
one
customer. With the facility card, you
program the device for this customer.
Thereafter, the device only checks credentials
that have been assigned to this customer.
Fitting
Depending on the context, the following
definitions are used:
In the narrower sense, a mechanical
subassembly consisting of a sign,
doorknob and doorknob pin of a door lock.
In the expanded sense, a collective term
for the functional and decorative elements
of a door structure. (Not to be confused
with door element.)
Front metal
On a mounted mortise lock, the visible lock's
narrow side, which is used to fasten the lock in
the door leaf.
Latch
In a door lock, a mobile arresting element for
locking the door leaf (see "Locked"). Due to
the mechanical spring action, the latch
assumes only
one
stable position. The latch
