INTERCOM INTERFACE MODULE
Art. 4897
The intercom interface Module Art. 4897 is contained in an 8
module DIN box.
Dimensions: 140x140x67 mm (8 DIN modules).
To access the withdrawable connection terminals, remove the side
cover as shown in the figure.
Art. 4897 must be supplied at 24VAC by means of transformer

The device manages a Max of 8 intercom extensions, connected to
the 4 outputs of the intercom interface Art. 4897. A MAX of 3
extensions in cascade can be installed for every extension of the
intercom network (see installation rules on page 24).
Configuration of the intercom network connected to Art. 4897 is
made to recognise the interface by means of simple self-
configuration of the article once the internal units connected to it
have been set (see "Programming interface module Art. 4897 for
self-learning" on page 29).
In the door entry phone only systems, Art. 4897 must be set to
Simplebus1 operation (see "How to set Art. 4897 for operation with
