Under-threat alarm system for armoured vehicles

The GAS system has been specially developed for use in armoured vehicles such as armoured limousines or cash-in-transit vehicles. The primary functions of GAS are a two-way intercom communication and an alarm that is triggered in the event of an attack on the vehicle. In addition, there is also an option of using GAS in conjunction with a beacon as a special signalling system.


  • The amplifier circuit developed for special-purpose vehicles creates a very high sound pressure level, even for the attack alarm – increased safety for vehicle occupants
  • Two-way intercom communication with the closed, armoured vehicle possible with very clear voice transmission
  • No intervention required in the vehicle body – easy installation, compact design of the components, discreet
  • Unique combination of intercom, special signal (pre-programmed with German homologation and US tones selectable) and attack alarm
