Glossary.
Entrance panel.
Set of audio and video devices that allow identifying the party asking to enter the dwelling via the outdoor station.
Indoor station.
Single video door entry or only audio door entry device that enables identifying the person at the speech unit that
made the call. Generally the indoor station, besides communicating with the external panel, allows carrying out
other operations such as opening lock, lighting stairs, etc.
Speech unit.
Generic term used to indicate the entrance panel or landing panel.
Pillar.
Term used to indicate the set of wirings connecting the indoor stations with the power supply.
Power supply.
Device that incorporates the drives for lock opening, the call generators and the necessary power supply both to
the pillar and to the panel.
Landing panel.
Set of audio and video devices that allow making a call to the indoor station(s) and identifying the party making
the call. It is generally installed for making calls from zones inside the building (landing, secondary entrances, etc.).
Self-start.
Optional function that allows audio and video communication between the indoor station and entrance panel or
indoor station and landing panel, without a call coming (from the entrance panel or landing panel respectively).
Intercom.
Optional function that permits audio communication between two indoor stations.
Bus.
Physical connection permitting the transit of the electrical signals necessary for the operation of the system; gener-
ally, both analogue (audio and video) and digital (commands) electrical signals can transit on the Bus and also the
power supply for the devices.
Identification code (ID).
Numerical code that univocally identifies the single device within the system. It is the name (in numerical format)
of the device.
Master.
Main object that manages the system. Typically we talk about the "Master Panel" that refers to the main panel (that
must be unique in the whole system) always identified with ID equal to 1.
Slave.
Secondary object in relation to the master; in general it is managed by the master. If we talk about "Slave Panel"
the secondary panels of the system are identified with an ID other than 1.
Basic programming.
Programming the main functions of a device. Generally, this programming can be done without the aid of additional
