GENERAL CATALOGUE
3000 Series
Intercoms & videophones
The
3000 Series
intercoms and videophones are the result of specific research and develop-
ment 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 and videophones series are compatible with the
old 900 Series and the new 3600, 5000 and 6000 Series and can be installed on the same
system (except the VX2200 digital systems where 900 Series products cannot be installed with
products from other series); the only difference between the 3000 and 900 Series is that the
3000 Series “call“ is electronic as opposed to an AC buzzer on the 900 Series. The 3000 Series
intercoms and videophones are available with additional services including:
--
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 on and off by the user.
The
“Privacy of speech”
disables the telephone when not in use. With this service the user has
two advantages:
--
The user has a private conversation with the door;
--
The lock can only be released by the user who is talking to the door.
On the digital systems VX2000, VX2200 and VX2300 the privacy of speech is standard on all
intercom and videophone 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.
To use this service, an additional wire is required from a door contact to the intercom.
