5.11.Faults or Flow Problems automatic transmission
(Refer to DR[3] Section 1.0.25 to 1.0.27; DR[4,5] Section 1.0.22 to 1.0.24)
RTM Elster AMCO module offers the possibility to automatically transmit radio frames when an occurrence is
detected. The following occurrences may provoke an automatic alarm :
Extreme Leak detection (High threshold) (encoder and pulse register only)
Residual Leak detection (Low threshold) (encoder and pulse register only)
Encoder Communication fault detections (encoder register only)
encoder reading error detection (encoder register only)
Tamper detection (pulse register only)
Low Battery warning detection
Back flow detection (encoder only)
It is possible to select for each type of occurrence whether or not an alarm frame is to be sent.
5.11.1.Time windows dedicated to alarm sending
Activating alarm in a system already configured to send information using pseudo bubble up mechanism can
lead to collisions. To avoid as much as possible these collisions RTM Elster AMCO embeds a parameter
that allows to configure time windows dedicated to alarm. These time windows will then not be used for
Pseudo Bubble Up time slot attribution. This mechanism allows to mix either Pseudo Bubble Up mechanism
and Alarm frame management without affecting system accuracy.
Example of Alarm Windows activation
In this example, to activate alarm windows every hour during 60 seconds, the parameter “Alarm Window
configuration” (0x57) must be set to 0x69.
By using this configuration the RTM Elster AMCO will allow alarm frame during 30 seconds every hour and
will start the first time on hour on dot taking into account its internal RTC.
In this example the request to configure alarm windows activation is done between 8:01AM and 8:59AM.

5.11.2. Automatic configuration of the destination route (via SDP)
RTM Elster AMCO integrates the CORONIS SDP feature “Self Discovery Protocol” used to identify the path
to reach the root of the network. RTM Elster AMCO uses this parameter to transmit its alarm frames.
When no path to reach the root is found, RTM Elster AMCO will erase the route contained inside its
parameters. The destination address will be equal to 0xFFFFFFFFFFFF. In such a case, RTM Elster AMCO
does not manage alarm frame since it has no idea of distant equipment radio address to send it to.
