GENERAL INFORMATION
The Single-residence Video Door Entry Kits Art. 8171 and Two-
residence Video Door Entry Kits Art. 8173 can be used in
residential or service sector buildings where effective access
control and simple installation operations are required.
In fact, just 2 wires between the external unit and the internal
monitor/s are required to activate the system (calls, intercom, video
automatic switch-on), plus two wires to provide the 12Vac power to
the external unit and electric lock.
A wide range of accessories to meet the needs of any type of
system is also available: as well as interesting standard
accessories, the system can also be extended by adding Video
doorphones and/or Telephones and/or external units.
In this way it is possible to have a maximum of two external units
with three internal units including Telephones and Video
doorphones for the single-residence configuration, and two external
units with six internal units including Telephones and Video
doorphones (three for each call Button) for the two-residence
configuration.
By means of appropriate settings (according to the table on
page 40) single-residence intercommunications (i.e. between
users having the same user code) and two-residence
intercommunications (i.e. between users not having the same
user code) are possible using Video doorphones as well as
Telephones.
Several Kits can be connected to a Simplebus main entrance panel
and/or a switchboard Art. 1998A.
See page 47 for further information.
