The RTU will wait for the configured inter-session delay between calls. You may configure the RTU to make from 1 to 5 notification attempts to the same destination before moving on to a new destination. If no acknowledgment is received, and the number of attempts is satisfied, the next destination will be dialed. The process will be repeated indefinitely, going through all the designated destinations in sequence and even looping back if necessary, until acknowledgment is received.
Note: The FCC requires that consecutive calls to the same destination be subjected to a minimum 10-minute delay. The requirement will be automatically enforced after the configured redial attempts are completed.
