2.1 Product Description
In principle, 2N ® SingleTalk (hereinafter referred to as ST) is a Speakerphone. It is
equipped with a microphone, loudspeaker, telephone line terminals, ALARM buttons,
backlit pictograms (as required by the applicable standard) and an optional CANCEL
input for door opening indication.
ST is available in two versions. The Universal version is designed for mounting
behind the pre-drilled (according to the drawing, see the Mounting section) lift panel.
The Compact version is provided with a metal case and can be installed quickly and
easily without advance preparation.
Operation
Push the ALARM button to activate the device. The “Wait” pictogram goes on
immediately, followed by the “Connection established” pictogram after communication
has been established.
Universal Version
The board with electronics is placed between the mounting panel and the printed
cover (see Fig.). The total dimensions are 65Ч130Ч24 mm. The loudspeaker and
microphone are fitted to the panel. Basic (slide-on) terminals are to the left and
extending modules (lift blocking and switch modules) to the right.
The extending module 913647 is under the cover (having no terminals). Small
connectors at the bottoms are intended for the induction loop (for people with bad
hearing) and LED indicators. Typically, backlit pictograms (even with incandescent
lamps) are connected to the product. Neither the pictograms nor the ALARM button
are included in the standard delivery (they are lift design elements).
Compact Version
The Compact version is provided with a robust metal case of the size of 100Ч185Ч16
mm. The built-in ALARM button is equipped with a yellow plastic pictogram (a bell)
and an ALARM sign for the blind on its sides. The backlit pictograms and induction loop
for people with bad hearing are in a window made of unbreakable glass. The
microphone and loudspeaker are vandal-proof too. Once installed, the product screws
are invisible from the lift cabin.
Caution
 The Compact version does not include the lift blocking module in the case
of telephone line failure. You can connect the module parallel to the
telephone line, e.g. in the machine room.
