Videophones (3371, 3471, 3376 & 3476)

Description

The Art.3371 is a digital videophone based on a “6 Wire BUS”, it includes 5 push buttons; a door-open

button, an alarm or camera recall (depending on the settings) button and three general purpose service push

buttons. The call is an electronic tone with a 3 level volume control which can be adjusted by the user. The

local door bell input has a different tonality from the main call. To connect the videophone to the “BUS”, use

the PCB connector provided with the mounting plate Art.3980. The videophone has an 8 way dip-switch to

set the PHONE ID, a 4 way dip-switch to set the video system (coax or non coax) and a trimmer (VR1) to

adjust the microphone volume; all accessible from the rear side of the videophone. With the 3000 series it is

possible to connect 180 videophones to the same system and if necessary it is possible to give the same

address to a max. of 3 (for those applications that require more units for the same apartment, it is also

necessary in this case to power locally one videophone). The door-open push button on the Art.3371 is also

the “call to concierge” (if there is one installed on the system), the “n” push button can operate as a camera

recall button (default setting) or as an alarm button (for use with the concierge or with an Art.512DR

configured as a generic service relay board) and the three service push buttons close to a common contact

(terminal 11 of the PC connection -“COM”)

Art.3371, 3471 VIDEOPHONE

The Art.3376 has one service button less than the Art.3371 but has some additional functions:

- the “privacy mode” which is activated by pressing the

push button, it is signalled by the red “privacy on”

LED and its duration (except when the push button is pressed again) depends on the 3 way dip-switch

(accessible from the rear side of the videophone).

- the visual indication of whether the door is open or closed given by the green “door open” LED: to use this

service, an additional wire is required from a door contact to the intercom.

Both models of videophones allow the connection of an optional relay board Art.402, for the activation of an

external sounder instead of the internal one.

5 Way Dip-Switch

(Default settings above)

When connecting two or three videophones

in series within an apartment without the

use of the video splitter (Art.316 or Art.894),

dip-switches 3 & 5 should only be switch on

at the end of line videophone.
