20.7 Alert Reception from Connected Sensors
An "ALR receive and ACK transmit" communication is available for every serial line
input. The ALR message from the sensor includes information about alerts from the
sensor, and is presented though the normal alert system. When you acknowledge an
alert, an ACK message is sent to the sensor to do remote acknowledge.
This interface is based on IEC 61162-1 and IEC 80/520/INF.
