IEC Siren Disc Aluminium
Order code: SW3760-001IEC ALUMINIUM SIREN DISC
A hard aluminium disc about 180mmD mounted on a central shaft so that it can be rotated with an electric drill or similar. The disc has 4 marked rows with 24, 30, 36 and 48 holes which is a ratio of 4, 5, 6 and 8.
When a fine jet of air is blown through the rotating holes a 'siren tone' is produced. The combined sound of all 4 holes creating the siren sound is a natural musical chord.
Air can be blown through the SW3770-001 Blow Tube by the mouth, but connecting the blow tube with a rubber hose to a source of compressed air at 100-200kPa pressure produces a better effect.
The disc is 1.5mm thick with a 40mm long spindle stepped to be dual diameter at 10mm and 6mm.
