Pirate Alarm System

The Pirate Alarm SystemCommand Courtyard scan is a system of devices used by the Space Pirates on several Homeworlds. It varies from planet to planet.
==Description==
===Metroid: Zero Mission===
In Metroid: Zero Mission, the Pirate Alarm System is used on the Space Pirate Mother Ship and in the Chozo Ruins in Chozodia. If any Zebesian sees Samus Aran, the alarms are instantly activated. Red lights flash, shutters close, and Zebesians quickly enter the room from nearby doors and run after Samus. The alarm is not activated if Samus stuns the Zebesian with her fully-charged Paralyzer before it sees her.
The Space Pirates have several independent devices that automatically trigger the alarm system. The first device that can set off the alarm is a visible green beam emitted by two small cylinder-like gadgets that, if breached, acts as a tripwire. Searchlights and floating-eye sensors can also trigger the Pirate Alarm System.
When the alarm system is activated for the first time, the music changes from Wrecked Ship to a frantic version of Crateria - The Space Pirates Appear. Once the alarms have been turned off for the first time, the simple beat from Crateria - The Space Pirates Appear takes over the role as the music that plays when the alarm system is inactive. After Samus acquires the Fully Powered Suit, a triumphant version of Brinstar (Metroid) continues to play regardless of whether the Pirate Alarm System is currently active.
===Metroid Prime 3: Corruption===
In Metroid Prime 3: Corruption, it activates when intruders are detected, followed by small antennas protruding from devices on the wall, flashing as they warn and summon Space Pirates to terminate the intruder. They are activated either by tripping laser devices or from small handheld alarms. Once the antennas are activated, Samus has a few seconds to shoot them until she runs out of time and is attacked by Space Pirates.
There is another device also found on the same planet that appear as pairs of towers which produce a beam invisible to all but the X-Ray Visor. Serving a similar purpose, it is part of the Pirate Alarm System and will alert nearby forces (in particular Commando Pirates) whenever Samus passed through it. Samus can avoid it by going into Morph Ball mode and moving beneath it.
Pirate Surveillance Drones patrol areas such as the Scrapworks. If they detect intruders, the alarm system is activated.
Sometimes, when Samus is sighted, Space Pirates will run in and activate a beacon that sends a distress signal.

==Trivia==
*In Metroid: Volume 1, a device similar to the alarm system was used on Jigrad to measure the height of Jigrad children that were to become Space Pirate slaves. Those who were too short would not activate the device and would then be terminated. Samus and fellow Federation Police members interfered while it was in use, saving the lives of Damara and several other children. Later, Kreatz contemplated on selling it. Consisting of two portions, typically a pair of towers, it fires a beam that connects them.
*The sound effect of the Pirate Alarm siren was reused from Metroid Prime 2: Echoes, where it could be heard in the final report cutscene when the Dark Splinters attacked.
*An alarm of lesser importance appears in front of the door leading to the Omega Pirate in Metroid Prime. This red alarm goes off when the Frigidite is melted.
*Within the Metroid Prime 2: Echoes Bonus Disc exists a moving sensor that may appear to be a early Pirate Alarm system, seen when hacking within the Agon Pirate Base. No such sensor appears in the final game however. It is possible these beta objects were repurposed as the sensors seen in Corruption (minus the scrolling).
