The Multi-Frequency back-up alarm provides a solution to potential noise pollution created by back-up alarms in confined or densely populated work areas by maintaining a safe warning signal for those in the danger zone of backing vehicles while minimizing disturbance to work site neighbors.
The Multi-Frequency alarm operates by emitting sound at multiple frequencies attenuated above 4000Hz so that the sound is perceived to dissipate more quickly than a conventional pure-tone alarm. In addition, the reverse mounted speaker design of the EA9724 and EA9780, and the driver technology used in the EA9070, models extends the life expectancy of the alarm, so much so, that a life of the vehicle warranty is offered.
