+ It is all recorded now, so you just press the button for the type of alarm you want. Each has a different meaning. You better not be making a mistake on this one.

Right then,
You are talking about a very old system, however you can still see it on old preserved ships.
The system you are talking about is a steam rotary whislte. Steam is admitted to the rotary whistle, and as the speed increases in the rotary part, the sound of the steam venting out from it goes up, hence getting the "whoop" sound.
It is usually controlled by a wire to the whistle that is on the funnel, the wiore simply being an extension of the handle on the valve. By pulling it on the bridge, it will open the valve, and letting it go, it will close the valve.
If you were to leave the valve open, the sound would reach a certain pitch, where it would remain, as the steam velocity cannot speed the up the rotor anymore, (it has reached its max speed for the pressure). When you close the valve the rotor slows down again, and when it is opened again, you get a new "whoop".
One ship in the UK which still uses a whislte like this is the SS Shieldhall. Which you can read about here. http://www.ss-shieldhall.co.uk
This type of whistle is no longer used, with the simpler air operated horn, which works similar to a foghorn.

1MC (The Whoop) is the term for the shipboard public address circuits on Naval vessels. This provides a means of transmitting general information and orders to all internal ship spaces and topside areas, and is loud enough that all embarked personnel are able to (normally) hear it. It is used to put out general information to the ship’s crew on a regular basis each day. The system consists of an amplifier-oscillator group which is located in the IC/gyro room, a microphone control station, portable microphones at each control station and loudspeakers located throughout the ship. Control stations for the 1MC announcing system are located at the pilot house, OOD stations on the quarterdecks, after steering and Damage Control Central area. The term "MC" is an acronym for Main Circuit.
During a casualty, The 1MC is a valuable damage control communication tool used by DCA (damage control assistant) to keep ship members alerted and informed of casualty location area, updated status, and incident response efforts by the DC organisation.
The 1MC is divided into smaller sub circuits, such as officer's quarters, and topside. At the option of the officer of the deck, some words are not passed on certain circuits.
The 1MC is also used for transmitting various alarm sounds to alert the crew of specific impending dangers such as:
* General
* Chemical attack
* Collision
* Flight deck crash
Other Circuits
* 2MC - between Engineer’s spaces
* 3MC - for the Hangar Deck areas
* 5MC - for the Flight Deck areas

This system was dumped after WW2. The system is a simple steam powered horn by pulling the horn lanyard you can make it sound just like in the movies. The earlier answers referred to the general quarters gong which is now standard and goes over a 1MC system. There was also a mechanical version that simply replaced a man working the horn. This horn was used to tell the crew to prepare for anti sub warfare.

American warships do not go "Whoop". American ships have three different alarms for general quarters, collision, (C)hemical(R)adilogical(B)iological. GQ is used for fire, abandon ship, man overboard, and other emergencies. The collision alarm is rapid high pitches sounds whose purpose is alert the crew of imminent danger and prepare for shock. The CRB alarm tells the crew to DogZebra (seal) the ship to minimize entry of dangerous air or fallout. There are sound files on the internet.

Is called the 1MC, a P/A system within the ship. On the outside will be rather loud, or its a warning alarm that a weapons system is about to fire.
