4.3 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, who monitors 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, 2N® Lift8 establishes connection with the control office (refer to Automatic Dialling for details). 2N® Lift8 plays the following announcements "Wait pleased, connection is being made“ to the person in the lift and "Press 1 for confirmation” to the control centre (if DTMF 1 confirmation is used). The received call has to be confirmed manually or automatically. The call is time-limited (“Caution, the call is ending”, but can be extended.

Refer to the Control Centre Instructions subsection for details for DTMF control during the call.

Caution

  • The ALARM buttons on the shaft and machine room audio units are always illuminated in the standby mode.

Outgoing Machine Room Calls

You can call any audio unit of the same 2N® Lift8 from the machine room (i.e. from the machine room audio unit, Part No. 918611E), activate functions and configure the 2N® Lift8 parameters. Press and hold for over 2 s  to activate the machine room voice menu. Press the TRIPHONY button to enter the machine room voice menu get through to the other audio units of the same lift and set up triphony with the other shafts.

Triphony

Triphony provides interconnection of audio units within one shaft. Press the TRIPHONY button in the machine room to set up triphony with another shaft.

This mode features a different setting of the automatic HandsFree mode: the microphones of active audio units are less sensitive than those operating in the ALARM mode. 

Triphony termination options

  • re-pressing of the TRIPHONY button
  • expiry of the time limit
  • incoming call/ALARM – processed preferentially

Check Call

A check call is an automatically made outgoing call (typically every 3 days). The purpose is to check the correct function of the system. This call is usually processed automatically in the control centre.

A check call can be sent to the control centre via PSTN, GSM, UMTS or VoIP. Set the values in parameters 071–076 and 981 (refer to Subs. 3.2, Table of Parameters).

Caution

  • Make sure that parameter 974 is completed where the lift Id is evaluated in the checking call transmission (applies to CPC and P100).
  • If the set of checking call memories is completely empty, use the set of ALARM memories.

Warning

  • With CPC or P100, be sure the set the checking call number to route the call to the 2N® Lift8 server. The call may not be confirmed and evaluated properly if it falls to sets 011–016.

Caution

  • Use parameter 811 to manually start a checking call without affecting the current checking call timing.


Operational Call

An operational call is made automatically when an event is executed (stuck button, battery replacement, rescue end, audio error). Use the Service Tool Configuration – Events menu for configuration. Refer to Subs. 5.3 for details.

These calls can be set up via the CPC or P100 protocols only (OK confirmation can only be made via CPC 2N ext or P100 2N ext).

If the operational call number is not entered, the call is set up via memories 011–016.

Warning

  • Be sure to set the checking call number to route the call to the 2N® Lift8 server. The call may not be confirmed and evaluated properly if it falls to sets 011-016.

Tip

  • For operational calls set the CPC Antenna 2N ext, CPC KONE 2N ext and P100 2N ext protocols, which allow the OK confirmations to be sent (batteries replaced, button repaired, audio repaired). You cannot set up these operational calls using protocols without 2N ext.

Incoming Call

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). 

Press 0 in the voice menu for connection with the last-calling audio unit.

Call Sequencing

If another request arises during communication, the calls are ordered according to priorities: Fireman has the highest priority, followed by Alarm. These calls suspend any lower-priority call. Calls with identical priorities are queued and processed one after another. Having done that, 2N® Lift8 recovers the suspended activity if possible.

Automatic Check Call Answering

A control centre with a PC workplace with the 2N® Lift8 Server receives calls automatically as configured. Configure the server using the  2N® Lift8 Control Panel.

Caution

  • If the checking call number (071-076) is not set, the call is made to the numbers in memories 011-016. Therefore, we advise you to always set the checking call number. If the CPC or P100 protocols are used and the call is directed to 2N® Lift8 Communicator, the call will not be evaluated correctly.
  • Operational calls can only be made via the CPC or P100 protocols. If memories 081-086 are empty, the call falls to the alarm numbers if the CPC or P100 confirmation mode is available. 2N® Lift8 Communicator cannot evaluate such calls.

Warning

  • Once fallen to the alarm numbers, the call may be confirmed incorrectly and evaluated as error if the checking call number is not entered.
  • If the operational call number is not entered, the call to 2N® Lift8 Communicator is evaluated as alarm. Therefore, set the right number to direct the call to the 2N® Lift8 server for proper evaluation and display in the 2N® Lift8 Control Panel.

Overview of Announcements

Announcement

Meaning

“Please wait for connection”

The announcement is played to the lift user when the call is being set up (before confirmation).

“This is an emergency call, to confirm connection press 1” The announcement is played to the control centre before call confirmation.

“Connection confirmed”

The announcement is played after call confirmation.

“This is communicator with ....” The announcement is played only if the control centre presses DTMF 3 after call confirmation. The communicator sends information on its product number or Id if available (parameter 974).

“Attention, the call will end the soon, to extended the call press 4"

The announcement signals during an outgoing/incoming call that the maximum call duration shall expire in 10 seconds.

“End of call”

The announcement is sent before hang-up.

“This is a checking call, to confirm connection press 1” The announcement is sent to the control centre only (if DTMF 1 confirmation is enabled).

Call End (Outgoing/Incoming)

A call is terminated (line hang-up occurs) if any of the following cases happens:

  • The busy or continuous tone has been detected*) (call end on PBXs).
  • The timeout for call confirmation expired (see parameter 913 setting).

  • The configured maximum call time has been exceeded (parameter 912). 10 seconds before the expiry, 2N® Lift8 plays “Caution, the call is ending” for you to extend the call with .
  • The  or  symbol has been received.
  • The time limit has expired during programming.
  • A higher-priority call request has arrived.
