GENERAL INFORMATION

The Single-Residence Video door-entry phone Kits Art. 8493,
8493B, 8493G and Two-Residence Video door-entry phone Kits
Art. 8494, 8494B, 8494G can be used in residential or service
sector buildings where effective access control and simple
installation operations are required.
In effect it only requires 2 wires between the external unit and the
internal monitor/s to activate the system (audio, intercom, video,
self-ignition), plus two wires to supply 12V AC power to the external
unit and electronic door-release device.
A wide range of accessories is also available to deal with the needs
of any type of system. In addition to interesting standard type
accessories, the system can also be expanded by adding video
door-entry phones and/or door-entry phones and/or external units.
In this way it is possible to have a maximum of two external units
with three internal units including door-entry phones and video
door-entry phones for the single-residence configuration, and two
external units with six internal units including door-entry phones
and video door-entry phones (three for each call button) for the
two-residence configuration.
By means of appropriate settings (according to the table on page
34), single-residence intercommunications (i.e. between users with
the same user code) and two-residence intercommunications (i.e.
between users which do not have the same user code) are possible
using video door-entry phones as well as door-entry phones.
Several kits can be connected to a Simplebus main entrance panel
and/or a switchboard Art. 1998A.
