User's Manual

• Resetting an alarm can be done from:
- The device on which the alarm is set. Alarm is reset after the call is Acknowledged
(LRMS [E2] messaging)
- The Input Module from which the alarm was set (eCAP, eAPI or eIO).
- An Incoming Confirmation call from eDMSAPI.
• You can use the I/O to set an alarm using a push button. This is issued after the button
is pushed, and is handled as a SENT alarm. The alarm cannot be reset by a push
button.
• The SENT, SET, and RESET commands:
- SENT. An incoming alarm that uses the specification SENT (Remove after SENT)
is sent to the device, and withdrawn after an Acknowledge from the handset. If the
device answers the call (Acknowledge), the alarm is reset.
- SET. This command sets an alarm that is only reset after a Reset is sent from the
same Input Module to the same Group/Alarm Id. In the case of a V.24 input module
that sends a message string, the same message string must appear in the reset
command.
- RESET. This command can reset an alarm that was earlier set using a SET
command. For the command to be successful, the alarm input must be exactly the
same as that set by the SET command, with exactly the same message. In the eAPI
Module, the Alarm ID, and the Group must be the same, but the message can be
different. Note that in the eAPI all outstanding alarms are reset, after receiving a
reset command.
• If an alarm is set, and you have set an overflow to an Alternative device, the overflow is
only activated after the device gives a NAK at each retry and the retry counter is
expired.
If you send a normal message to a DECT extension that is within reach of the radio signals
and is switched on, the overflow never takes place because DECT Messenger receives
an ACK. Only if the handset is switched off, or not in reach of radio signals, does the DMC
generate a NAK; then the message goes to the Alternative device after the specified
number of retries.
If you send an urgent message to a DECT extension, and the user of the DECT extension
does not press OK or Delete on the handset, the DMC sends a NAK after 30 seconds
ringing time. The message goes to the Alternative device after the specified number of
retries.
• If an alarm is set, and an overflow occurs to an alternative device, the alarm can only be
reset, with an alarm input from the same Input Module with the same Alarm Identifier,
however, with the properties: *RESET after *SENT.
• After you receive an alarm through eAPI, the options shown in
Table 10: Options for alarm
handling on page 107 apply to alarm handling:
