VistaKey Installation Guide
A–2
Door Strike - An electromechanical locking device typically installed in a doorframe to
enable locking and unlocking of the door by electrical or electronic means. Internally, the
device consists of a solenoid to which power is applied, causing a plunger to move linkage,
which releases a locking mechanism.
DSM (Door Status Monitor) - A zone in an access control system committed to the
monitoring of a door sense switch. The door sense switch reflects the state of the door (open
or closed) and also allows the system to determine if the door has been forced open or held
open too long.
E Entry Reader - An input device installed on the entry side of an access point door. At this
device, individuals are required to identify themselves to the system so that their access
privileges may be examined in order to determine if they should be allowed to pass into the
protected area. The term is “entry reader” because in most cases, the device is a card reader
at which a cardholder must present his ID card.
EOLR Supervision (End-of-Line Resistor Supervision) - A mode that is used to detect
when someone has cut or shorted a cable monitoring a zone, such as a door sense switch. A
resistor can be placed in the zone’s circuit at the protected point such that the controller can
detect line trouble, in addition to fault and normal conditions.
Event/Action - An option programmed by the user that allows system functions to be linked
to a system event. Upon the occurrence of the system event, the action is performed.
Executive Privileges - An option that can be granted to cardholders to allow them full
access to all of the system access points.
Exit Only - One of the modes in which an access point may be configured to operate. In this
mode, the access point only accepts exit requests. Any entry reader is ignored.
Exit Reader - An input device that is installed on the exit side of an access point door. At
this device, an individual is required to identify him/herself to the system so that their access
privileges may be examined in order to determine if they should be allowed to pass out of the
protected area. (See also: Entry Reader)
F Form C Relay Output - A Form C relay output is a configuration comprised of a Common
terminal point, a Normally Open terminal point, and a Normally Closed terminal point. With
the relay in a de-energized state, the Common and Normally Closed points are connected to
each other, and the Common and Normally Open points are disconnected from each other.
When the relay energizes, the Common and Normally Closed points disconnect from each
other and the Common and Normally Open points connect to each other.
Free Access - See Bypass (Access Point)
H Holiday - A component of time schedules that defines days of the work week when the
“normal” work schedule does not apply to the premises. For example, Thanksgiving Day
would be considered a holiday.
K Keypad - Typically a 12-button arrangement of momentary push buttons used to transmit a
code to the system based on a specific sequence of keystrokes. The keypad generally
resembles a telephone keypad with respect to the relative positions and key name
assignments.
L Locked (Access Point) - A mode that latches the door of the access point. The access point’s
readers will be disabled for access control functions. The access point does not allow any
accesses or egresses in the Locked mode.
M Mag Lock (Magnetic Lock) - A large coil of wire mounted to a door frame, that when
current is passed through the coil, creates a strong magnetic field. A large metal plate is also
secured to the door, and is held tightly against the coil of wire by the strong magnetic field.
