The leakage alarm is saved with a date stamp, in both daily register for 460 days and in monthly register for
36 months. Furthermore, it is saved in the info code register of the latest 50 info code events. Together
with the info code event, a time indicator with seven time intervals, which indicates how long the info code
has existed, is registered.
The Wireless M-Bus signal includes the LEAK code. If the LEAK code is active, or has been active within the
latest 30 days, a time indicator with seven time intervals will indicate how long the info code has been
active.
Info code - BURST
This info code activates if the flow exceeds a given value for a continuous period of 30 minutes.
This can be a sign of a burst in the pipe installation, which requires prompt action.
The size of the 30-minute flow (which prompts the info code BURST) can be determined by the customer
when submitting the order, and later by Metertool. The following options are available:

The info code BURST disappears when the flow falls below the above-mentioned limit. It can take up to 64
seconds after the flow has fallen below the above-mentioned limit until the info code disappears.

may occur in systems with many connected households. Users and water utilities must therefore, be
critical of the burst alarm.
