4.4 Function Description (for Advanced
Users)
Purpose of Section
The purpose of this section is to help technicians solve problems, if any. If the system
fails to work properly and a well-trained technician monitoring its operation step by
step according to the description included herein gets to a point where the description
and reality are in contradiction, he or she describes the contradiction, thus facilitating
troubleshooting. This procedure often reveals that the system works properly but the
user had a different idea of how to use it.
Outgoing Call
The process starts whenever the ALARM button is pressed on any audio unit. (in the
lift cabin audio units, the CANCEL input may delay or block calling, refer to parameter
914). After the ALARM button is pressed, the LN, LN establishes connection with the
dispatching office (for details see the Automatic dialling section). The LN replays a
message identifying the LN and the calling audio unit, as well as the following
instruction for the dispatching centre: “Press 1 for confirmation”. The received call has
to be confirmed manually or automatically. The call is time-limited (by the “Attention,
the call is ending” message), but can be prolonged.
For (DTMF) control during a call see the Dispatching Centre Instructions subsection.
Machine Room Call
You can call any audio unit in one LN system from the machine room (i.e. from the
machine room audio unit, item no. 913611, to which a telephone set is connected).
Furthermore, you can activate functions and program LN parameters with the machine
room audio unit. To activate the machine room audio unit, pick up the attached
