3.3 Alarm Levels
A detector may signal different levels of alarm, indicating the amount
of smoke or gas currently present. These are;
• Fire Alarm Level (the highest level)
• Fire Warning, including:
- Prealarm Level
- (the lowest level Early Warning is not yet implemented)
Note that only the Fire Alarm Level is indicated on the Repeater Panel
BU-320.
Whenever a detector detects a transition from one alarm level to
another, this event is reported to the system as an Early Warning (not
yet implemented), Prealarm or Fire Alarm signal, which in turn will
initiate the appropriate actions.
