Non-latched alarm

In a non-latched mode, the ON signal switches between ON and OFF state texts and the
corresponding LED colours. Alarm acknowledgement (ACK) clears the last time stamp
line of the alarm view, but leaves the corresponding alarm LED state unchanged. An
event is generated on the rising and falling edge of the ON signal and by acknowledge-
ment.
