4. Commissioning

Once all the electrical connections have been put in place, the DELTA intercom can be
switched on. The mains adaptor should now be installed and connected.
The connecting plug on the mains adaptor should be plugged into the appropriate socket in
the Main Control (see sketch on previous page).
The mains adaptor is then connected to a socket (230V AC - 50 Hz). When the red LED
beside the mains adaptor connection is lit, it indicates that the intercom is getting current.
WARNING:
The intercom must never be connected directly to the mains without the mains
adaptor.
Once the intercom is getting current, it carries out an auto-test.
At this point, all the function buttons light up simultaneously for a brief moment and an "8"
shows in the display. This helps the operator establish if all the display elements are working
properly.
The system then carries out an automatic RESET, indicated by an "r" in the display.
Once all the buttons are extinguished and there is nothing more to be seen in the display, the
auto-test has been completed successfully.
Note: In a system with several extensions, the number of the current connection appears in the
display.
If this does not happen, there is a fault. Please check the leads on the individual components
again.
If there appears to be no fault in the wiring, the intercom should be manually reset. (See p.29 -
"Reset to Factory Settings".)
Note: When this function is carried out, all the settings changed so far are deleted and
replaced with the standard settings.
If using the "Reset to Factory Settings" function does not bring an improvement, or if this
function cannot be carried out, there may be a technical fault. In this case, please contact our
customer service.
If the intercom was started successfully, it may be necessary to change certain equipment
parameters. (Operating several extensions, or having accessories connected, changing the
operation mode, etc.)
All the possible settings are described in detail from p. 22.
The basic operating functions of the DELTA intercom system are described below.
