General information

The Two-Family Door Entry Monitor Kits Art. 8173I 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 two
wires to provide the 33 V DC power supply for the external unit and the
electric lock.
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 3 internal
units including door-entry phones and door entry monitors for single-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.
