The remote device must send an acknowledgment frame (command 0xC0) to confirm reception of the alarm
frame and end dialog.

If the RTM Elster AMCO does not receive this acknowledgment, it re-transmits the alarm frame several time,
with a delay between each retransmission. The delay, and the number of retries depend on the equipment
type used.

ATTENTION:
As mentioned above in this document, it is not recommended to enable alarm frames when RTM
Elster AMCO is programmed to send periodically its information. This could cause collision on
the radio medium and so lead to a loss of information coming from the RTM.
