Alarm annunciators and displays aboard Fireboat 2 include audible, visual, or
text display formats, or some combination of these three. This section is
intended to familiarize fireboat personnel with the various alarm and warning
systems, and to describe the appropriate response in the event of an alarm.
With the exception of the General Alarm (which is activated manually from the
Pilot positions), alarms and warning lights activate automatically when unusual
or significant conditions occur.
