The Pirate Alarm System is a system of devices used by the Space Pirates on the Pirate Homeworld. It activates when intruders are detected. When activated, small antenna protrude 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.
