The Multi-Frequency back-up alarm provides a solution to potential noise pollution created by conventional back-up alarms in confined or densely populated work areas. The Multi-Frequency alarm maintains a safe warning signal for those in the danger zone of backing vehicles while minimising disturbance to work site neighbours. The Multi-Frequency alarm operates by emitting sound at multiple frequencies attenuated above 4000Hz.
