Connection Of The Components - Sitec DELTA 2.0 Operating Instructions Manual

Connection of the components

The individual components of the intercom system have pluggable connecting leads. There are markings for the
corresponding connecting leads above the connection sockets of the devices.
All components converge at the Delta central control. The central control has 8 connection sockets: Four
connection sockets for the operator's side (Operator) and four connection sockets for the customer's side (Public).
For technical reasons, numbering of the connection sockets is from right to left. The main control must always be
connected to the connection socket Operator 1 (rightmost). The main control is necessary to operate the intercom
system. The numbering of the connection sockets on the central control corresponds to the allocation of numbers
on the operating interface of the main control.
The illustration shows as an example the simplest installation of an intercom system with a central control, power
supply, a main control at the operator's side (Operator 1) and a desktop extension on the customer's side (Public
1).
The following components can be directly connected via the connection sockets Operator 2,3 and 4 as well as
Public 1 and 2: desktop extension (Art.-No. 200 140), built-in extension (Art.-No. 200 141), headsets via the
headset adapter, three panel strip (Art.-No. 200 145), distribution box (Art.-No. 200 180) und door intercom (Art.-
No. 200 165). Only signal amplifiers (Art.-No. 200 130) are allowed to be connected to Public 3 and Public 4.
Further accessories can be connected via the signal amplifier, even over larger distances.
Attention: Only connect the individual components to the signal amplifier and to the central control when the
power supply / plug is disconnected.
