HEINRICH is a global manufacturer of public address and audio systems for applications across the transport sector, including airports.

The company has extensive experience working in media, safety, energy, and audio fields, providing complete solutions for public address voice alarm systems (PAVAS), audio-video, closed-circuit television (CCTV), emergency lighting and loudspeakers.

HEINRICH’s voice alarm controller (VAC) airport solution is a stable solution that offers 100% redundancy of the main controller for large installations. The DVA series is a user-friendly system, which is suitable for small airport installations.

Our engineers prepare acoustic simulations for each system using EASE software, which can accurately depict the acoustics of a high-reverberation area such as terminal buildings with glass, gloss or metal structures.

Public address and voice alarm systems for airports

HEINRICH offers an extensive range of loudspeakers suitable for departure, arrival, security, boarding and airside areas of the airport.

The VAC public address and CCM8 amplifier changeover offer 100% redundancy with integration with other services such as the flight information display system (FIDS), fire and emergency systems.

The PMC8 keypad for the PMC8 keyboard extension provides a network and touchscreen microphone for an increased display and control of district / group, with up to seven MIC extension units.

The PMC8-TM is used for remote operation of the VAC system, including the selection of system voice information and zone paging. This includes support system zones / group selection, zone monitoring, volume adjustment and status display. It features a 7in touchscreen.

Amplifiers for airport terminal buildings

The DPA range digital class-D power amplifier is one mountable rack unit with minimal power consumption and higher efficiency. It saves installation rack space and generates less heat for an extended lifespan.

The range includes:

  • Single Channel: 120W, 240W, 350W, 500W
  • Dual-Channel: 120W, 240W, 500W
