Drumgrange has developed a range of Acoustic Hailing Devices (AHD). The AHD family allows security users to intelligibly communicate to personnel, vehicles and ships to hail, warn & establish secure areas.

The AHD Family consists of:

  • 4 Horn Device – A fully marinised, highly flexible, long range Acoustic Hailing Device with an effective voice communications range of 1500m. The device’s unique modular construction allows this system to be fully assembled and made functional in less than 15 minutes with just one operator.
  • 2 Horn Device – A variant of the 4 Horn device, the 2 Horn AHD has an effective communications range of up to 1000m over loud background noise.
  • Manpack – Originally developed for German InfoOps, this Man Portable system weighs from just 5.5kg and delivers clear speech at up to 800m.
  • AHD 360° - A mass notification system for voice and music transmissions covering a full 360° broadcast area over a radius of 50-250m.
  • Remote Control AHD - A remotely operated Acoustic Hailing Device (RCAHD) designed for manned or unmanned installations.
