Delta 2.0 Intercom System - Sitec DELTA 2.0 Operating Instructions Manual

Delta 2.0 Intercom System

The DELTA 2.0 intercom system has been specially developed and tested, in close consultation with our
customers, for use in banks, at cash desks, porter's lodges in companies, late-night desks, ticket offices, border
crossings, customs offices, tollbooths, exchange offices, administrative bodies and authorities, as well as for door
interlock systems.
The intercom system ensures comfortable and trouble-free communication between the operator of the system
(employee/operator) and the public (visitor/ customer).
The DELTA 2.0 intercom system is installed as a modular system and can be simply adapted to individual
requirements and to structural conditions. The intercom system can be extended – even at a later stage - without
any problem, with the accessories offered by SITEC.
The main item in the intercom system is the central unit (central control, Art.-No. 200 000), to which all the
components are connected directly or indirectly. The intercom system is operated by the main control (Art.-No.
200 020). All other components are called extensions. The main control is always required. Only one main control
can be connected to each intercom system. The operator can control the different functions of the intercom
system and the connected accessories (announcement loudspeaker, door opener) using the illuminated buttons
on the main control.
The intercom system provides reliable communication between a secure area (inside), where the main control and
the operator/employee are, and a non-secure area with public traffic (outside). Each side can have a maximum of
four individual extensions that are connected via cable to the central control. Only one conversation at a time is
possible. It is not possible to speak simultaneously between different inside and outside extensions. The
components that can be connected on the inside are one main control, headsets, as well as so-called passive
extensions (desktop or built-in extensions as well as microphone-loudspeaker-three-panel-strip) for further
employees inside. It is not possible to speak between the intercom extensions on the inside.
At least one extension has to be connected on the outside. Up to four different extensions can be connected on
the outside at a maximum. Extensions for the outside can be desktop or built-in extensions, three-panel-strips as
well as combinations of loudspeakers and microphones which are connected via a distribution box at the central
control. Of the four outside intercom extensions, only two may be door intercoms including door opener. It is
possible to connect further door intercom extensions without door opener at the two remaining sockets.
Communication between the outside intercom extension (customer/visitor) and inside intercom extension
(operator/ employee) is in full duplex mode, meaning that the parties can speak and listen at the same time, as in
normal communication. The new DELTA 2.0 intercom system reduces feedback almost completely.
The individual components have pluggable connections and have to be plugged into the corresponding marked
socket in the central control. Assembly and connection of the individual components is described as follows.
