The Art. 3171 is a digital intercom based on the “2 Wire BUS”, it includes a door-open button and a service button plus an electronic call tone with a 3 level volume control which can be adjusted by the user. Internally, the intercom, has an 8 way dip-switch to set the PHONE ID, a terminal board with 6 terminals for connection to the bus and other connections and a trimmer (VR1) to adjust the microphone volume. With the 3000 Series it is possible to connect up to 180 intercoms on the same system. If required it is possible to give the same address for a max. of 3 intercoms (for applications that require more units in the same apartment). The door-open push button on the Art. 3171 is also “call to concierge” (if there is one on the system) push button, while the “” push button works on the terminals “SW SW” (Max 30Vac/dc 0,2A) of the terminal board.
The Art. 3172 is the same as the Art. 3171 plus the privacy switch which activates the “privacy mode” (the user can’t receive incoming calls).
The Art. 3176 is similar to the Art. 3172 but in this case the “privacy mode” is activated by pressing the push button. It is signalled by the red led “privacy on” and its duration (except when the same push button is pressed again) depends on the 3 way dip-switch (housed inside the intercom) settings. The Art. 3176 doesn’t have the service push button but it has a green led “door open” to give the user a visual indication of whether the door is open or closed: to use this service, an additional wire is required from a door contact to the intercom.
All 3 models of intercoms allow the connection of an optional relay board Art. 402, for the activation of an external sounder instead of the internal one: the board is housed inside the intercom, connected to the JP2 (red wire on side “+”) and the JP1 jumper (normally on A position) must be moved to the “B” position.The Art. 3171 is a digital intercom based on the “2 Wire BUS”, it includes a door-open button and a service button plus an electronic call tone with a 3 level volume control which can be adjusted by the user.
