Electric Vehicle Alarm Systems
We offer a range of alarms to suit all types of electric and hybrid vehicles from cars through to vans, trucks and buses. Our acoustic vehicle alerting system (AVAS) will meet UNECE regulation 138 and will be possible to be re-programmed to meet changing requirements.


While powered but stationery the AVAS system emits a low level white noise/engine sound to simulate an idling engine. Volume and pitch increase with speed up to 20mph, when it cuts out as the road noise takes over. AVAS remains muted when either ‘Park’ or handbrake is applied. When reverse gear is selected front speaker is muted and rear speaker emits a fixed db warning.
