4.2 Control Centre Instructions


  1. Press the ALARM button on any audio unit to make 2N® Lift8 call the control centre (refer to Automatic Dialling for details).
  2. A received call is either confirmed as configured (parameters 111–116 > Confirmation mode for memory 1–6  ALARM call – set 1). By default, confirmation of DTMF 1 is set in 2N® Lift8.
  3. If the control centre is equipped with the 2N® Communicator application, you can configure automatic sending of DTMF 1 after call pick-up.
  4. The call is time limited (press button 4 upon warning announcement “Caution, the call is ending” to extend the call).
  5. You are recommended to end the by pressing 5 or #.

Control Room-to-Lift Calling

The control centre can also call back to the communicator. The CU automatically receives every incoming call, identifies itself and, via a voice menu (DISA), offers you another function to get through to the required audio unit. Incoming calls are time limited as outgoing calls and are processed in the same way (extension, termination).

Tone Dialling Control during Call – Long Command List 

Where automatic dialling with confirmation is used, it is possible to use tone dialling for 2N® Lift8 control during the call according to the table below. For simplification, commands 1 to 5 are arranged in the sequence they are usually used in.

DTMF symbol

Description of function

Only where automatic dialling repetition is enabled (with confirmation DTMF 1). This symbol is used to confirm a successful call to 2N® Lift8. 2N® Lift8 mutes the played-back announcement and, optionally, sends the identification code (DTMF). The call goes on until the timeout end and any of the following commands may be used.

Announcement playing end.

Repeated voice module playback for one replaying of the announcement.

Call extension. The call is extended as defined in parameter 912 (120 seconds by default) upon this command. Can be used repeatedly.


Call termination (does not work until the call is confirmed).

This table applies to the Automatic voice dialling with confirmation mode.


  • Rarely, 2N® Lift8 may not identify the above listed commands reliably during message playing or voice communication. This is due to the essential principle of the telephone line function where DTMF signalling is mixed with the call and thus may be masked by certain speech tones or noise. This, however, is not a defect of the product.
