Collision/Flooding Alarm
The collision alarm is used to warn of imminent collision or actual flooding and is accompanied by a succinct statement of the emergency such as "flooding in engine room lower level" (if possible; flooding is deafeningly loud).
The alarm is a slowly rising and falling siren, rather like a stereotype American police car siren, which sounds continuously as long as the switch is held on.
The collision/flooding alarm handle is a red cog shape.

Famous quotes containing the words collision and/or alarm:
“When the wind carries a cry which is meaningful to human ears, it is simpler to believe the wind shares with us some part of the emotion of Being than that the mysteries of a hurricane’s rising murmur reduce to no more than the random collision of insensate molecules.”
—Norman Mailer (b. 1923)
“Generally speaking, the political news, whether domestic or foreign, might be written today for the next ten years with sufficient accuracy. Most revolutions in society have not power to interest, still less alarm us; but tell me that our rivers are drying up, or the genus pine dying out in the country, and I might attend.”
—Henry David Thoreau (1817–1862)
