General information

The Two-Family door entry monitor kits Art. 8472MB can be used in residential or service sector buildings where effective access control and simple
installation procedures are required.
In fact, it only requires 2 wires between the external unit and the internal monitor/s to activate the system (calls, audio, video self-ignition), plus 2 wires to
power the external unit and the electric lock and 2 wires to power the door entry monitor internal unit.
A wide range of accessories is also available to deal with the needs of any type of system; in fact, in addition to interesting standard type accessories, the
system can also be extended by adding door entry monitors and/or door-entry phones and/or external units. This makes it possible to reach a maximum
of 2 external units with 6 internal units including door-entry phones and door entry monitors for the two-family configuration.
By means of appropriate settings single-family intercom communications (i.e. between users with the same user code) are possible using both door entry
monitors and door-entry phones.
Several kits can be connected to a Simplebus main entrance panel and/or a switchboard Art. 1998A.
