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 65×130×24 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 100×185×16 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.
