Category:Electromechanical Sirens
Electromechanical sirens generally use a cylindrical, slotted rotor inside of a similar stator. The rotor spins inside the nonmoving stator, causing air to be forced out like a squirrel cage blower. The slots are alternately blocked and opened as the rotor spins, causing vibration and sound.
