Telephone commands

*#00 - Enter alarm numbers

This command is used to define the phone numbers that are dialled after the alarm button is pressed. Dialling always starts with the first configured number and continues until the alarm is successfully acknowledged.

The number of dial attempts is configurable.
Entering “#” within the phone number inserts a 1-second dial pause.
Entering “*” causes the NRT to wait for a dial tone.

#*01 - Dialing mode

The NRT XT supports both DTMF (tone dialling) and pulse dialling.
Additionally, there is a “leased-line” option. In this mode, no dialling takes place after the alarm button is pressed. Call routing must instead be handled by an external PBX or by the telephone network operator.

#*02 - Dial retries

The number of dial retries performed for each event (alarm, timer call, status message) is factory-set to a maximum of 12 attempts for safety reasons.
This value can be reduced or — at your own risk — set to unlimited.

#*03 – Talk Limit

The maximum call duration is limited for safety reasons.
After the maximum duration has elapsed, the call is terminated and the NRT disconnects.

Factory setting: 6 minutes

#*04 – Configure “INPUT” terminal

#*05 – Assign microphones and speaker module to alarm buttons

Command *#05 defines which alarm button activates which speaker module and microphone.

Factory setting:

• alarm button ALARM #1 activates speaker module and microphone at terminals SM #1 and MIC #1

• alarm button ALARM #2 activates the speaker module at terminal SM #2

• alarm button ALARM #3 activates the loudspeaker/microphone unit integrated in the NRT

This assignment can be changed using *#05.
For example, it is possible to always use the internal loudspeaker and switch only the corresponding microphone depending on which alarm button was pressed.
After entering *#05, a three-digit code must be entered:

#*06 - Voice communication

This command switches from programming mode to voice communication with the last active voice unit.

You can return to programming mode at any time using the following key sequence:

#*07 - Service communication

Command *#07 exits programming mode and switches directly to voice communication with the last active intercom station.
In addition to the previous command *#06, the maximum communication time for this connection is set to 30 minutes.

#*09 - Factory Reset

Restores the NRT to factory default settings.

#*10 - Audio Reset

Resets all audio settings to the factory defaults.
This command is useful if feedback occurs due to incorrect audio settings and the NRT no longer responds to key input.

#*12 - External line access

External line access is only relevant when operating the NRT on PBX extension lines.

Three settings are available:

Off:
Line access is disabled; all phone numbers are dialed exactly as entered.

Permanent:
The access code defined under command *#14 “Access code” is always prefixed to the stored phone numbers.

Automatic:
The NRT checks the dial tone to determine whether the connection is a PBX extension or a direct line.

If a PBX is detected, the access code defined under *#14 “Access code” is automatically prefixed to all stored phone numbers.

#*20 - Time, date

This command is used to set the current time and date. The input is made in 24-hour format.

#*21 - Timer-call time, timer interval

To activate the test calls required by DIN EN 81-28:2022 between the NRT and the alarm center, a timer-call time must be set and the timer-call function must be enabled at the desired interval.

According to DIN EN 81-28:2022, the timer call must be performed at least every 3 days (72h).

#*22 – Service number, timer type

To configure the timer call, a service number and a timer type must be defined.

#*23 – “Timer-call fault” indication

According to DIN EN 81-28:2022, an unsuccessful timer call must be indicated in the lift car by alternating flashing of the pictogram indicators.

#*29 – Device number

When connecting an NRT to a control center that uses the Telegärtner data protocol, the device number is used to identify the alarm.
Normally, this device number is assigned and programmed by the control center.
If the control center does not support programming the device number, it can also be set manually using a DTMF-capable telephone.

#*30 - P100 ID-Code

This command is used to enter the ID code required for connecting the NRT to control centers that support the P100 data protocol.
The ID code must always be entered as an 8-digit value; shorter codes must be padded with leading zeros.

#*31 – Configure terminal “OUTPUT”

This command defines the behavior of the configurable voltage output OUTPUT.

The following operating modes are available:

#*33 – Set phone numbers and type for alert messages

Configuration of the phone numbers and type used for transmitting alarm messages.

#*34 – Alert messages

Defines which alarm messages are transmitted and whether only fault messages or both fault and restore messages are sent.

#*35 – Audio and alarm button test configuration

Defines which alarm button (and its associated speaker/microphone combination) is checked during the automatic audio test.
If the alarm button test is enabled, the function of the selected alarm button is checked as well.

#*55 – Remote alarm test

This command allows triggering an alarm remotely for testing purposes.

After the command is entered, the NRT disconnects the call and initiates an alarm, taking the configured alarm filtering into account.

#*57 – End-of-alarm / Acknowledgement

Configures how the NRT behaves after the voice communication for an alarm has ended.

*#58 – Alarm sound

This command activates an additional alarm sound and selects its tone.
When the alarm sound is enabled, the NRT plays the selected tone through its speaker into the lift car while the alarm button is pressed.
The alarm sound is disabled as soon as the NRT starts dialing.

*#60 – Voice Communication Code

When call blocker is enabled, the default sequence to establish voice communication is #6.

Command *#60 changes this digit sequence as required. Up to four digits are allowed.

The hash symbol # is not programmed but must always be entered during use.

#*70 – Bus address assignment

This command defines whether the NRT operates as a single device or as a bus device in multi-device mode.

#*72 – Alarm type

This command defines how the NRT behaves when dialing the four possible alarm numbers. A detailed description of the operating modes is provided in the referenced section.

#*73 - Info message

This command activates the info message that is played into the car after the alarm button is pressed. The message informs the trapped person about the initiation of the alarm and provides reassurance during the waiting period.

#*75 – Recording the info message

The sequence #*75 starts the recording of the message. After the input is entered, a tone indicates the start of the recording. The message can now be recorded using the microphone of the telephone handset. The recording is terminated by pressing digit 8.
The maximum recording time depends on whether the fault message function (see referenced section) is enabled.

• If the fault message is disabled, the maximum recording time is 10 seconds.

• If the fault message is enabled, the maximum recording time is 5 seconds.
  Any existing message is overwritten when a new recording is made.

#*76 – Playback of info message

#*77 – Recording the identification message

This sequence starts the recording of the identification message required to identify and assign the lift alarm when the NRT connects to a phone. The maximum recording time is 20 seconds. During a lift alarm, the message is played to the called party until the call is acknowledged.

#*78 – Playback of the identification message

#*81 – Fault message

If a fault prevents the lift alarm from being forwarded, a voice message can be played into the car.

#*82 – Recording the fault message

This telephone code starts the recording of the fault message that is played when no lift alarm can be transmitted. The maximum recording time depends on whether the info message function (see referenced section) is enabled.

• If the info message is disabled, the maximum recording time is 10 seconds.

• If the info message is enabled, the maximum recording time is 5 seconds.

#*83 – Playback of the fault message

#*88 – Changing the security code

To prevent unauthorized remote access to the configuration, the security code can be changed.

#*91 – Alarm latency

To prevent unintended false alarms, a minimum activation duration (latency) of the alarm button is required before a lift alarm is triggered. A valid lift alarm is stored until it is cleared. While a lift alarm is stored, neither alarm delay (latency) nor alarm filter is applied when the alarm button is pressed again. This setting applies to all alarm buttons.

#*97 - Privacy tone

When this option is enabled, a periodic tone is played into the car to inform the occupants that an active voice connection is established and their conversation may be monitored.

#*98 – Line impedance

The line impedance significantly affects the quality of data transmission and the quality of the voice connection towards the alarm receiving centre. Depending on the type of phone line used, the setting should be adjusted accordingly.
