# Alarm Reset Time-Out After Acknowledgment

As shown in the figure above, when an ACKNOWLEDGMENT is received, the RTU begins timing out the Alarm Reset Time (default = 1 hour).

Further calling on behalf of that channel is suspended, regardless of further activity at that particular input during this period. If new alarms occur on other channels during this period, the unit will go back into the UNACKNOWLEDGED ALARM State and dial the first appropriate Destination, with dialing continuing until a new ACKNOWLEDGMENT is received.
