NOTE
• When multiple alarms of different priority levels occur simultaneously, 
the TM80 selects the highest priority alarm to light the alarm lamp and 
issue the alarm tone,
• When multiple alarms of different priority levels occur simultaneously, 
the TM80 only displays the messages from the highest priority alarm.
