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)
“Dignity takes alarm at the unexpected sound of laughter.”
—Mason Cooley (b. 1927)
