The Siren is a machine block from Atomic Science.
The siren is a block that can sound an alarm when powered by redstone. The redstone current must be directly pointing into the siren in order to trigger it. The siren's pitch can be adjusted by right clicking or shift-clicking it with a wrench, while the siren's volume can be increased by placing more siren blocks next to the main siren block.
