The 3000 series intercoms are the result of specific research and development into new designs and materials. One of the main new features is a 3 level volume control for the electronic call tone. The 3000 intercoms series is compatible with the 900 series (which will remain in production) and can be installed on the same system; the only difference between the 3000 and 900 series, besides the redisigned exterior, is that the 3000 series "call" is electronic as opposed to an AC buzzer on the 900 series.The 3000 series intercoms are available with additional services such as:

-Privacy of call;
-Privacy of speech;
-Door open signalling.

The "Privacy of Call" is a service that allows the user to enable or disable incoming calls. The service can be timed or untimed:

-Timed privacy will automatically switch off after the programmed time elapses;
-Untimed privacy must be switched off manually by the user.

The "Privacy of Speech" disables the telephone when not in use. With this service the user has two advantages:

-The user can have a private conversation with the door;
-The lock can only be released by the user who is talking to door.

On the digital systems VX2000, VX2100 and VX2200 the privacy of speech is standard on all intercom units.

The "Door open signalling" is a service that will give the user a visual indication of whether the door is open or closed:

-LED ON door open;
-LED OFF door closed.

NB. To use this service, an additional wire is required from a door contact to the intercom.
