The ECCO Multi-frequency Back-Up Alarm provides a solution to potential noise pollution created by conventional tonal back-up alarms in confined or densely populated work areas. Those Multi-Frequency alarms maintain a safe warning signal for those in the danger zone of backing vehicles while minimizing disturbance to work site neighbors. Multi-Frequency alarms operate by emitting sound at multiple frequencies attenuated above 4000Hz.
Emits sound at multiple frequencies attenuated above 4000Hz.
Warning signal is more directional and perceived to dissipate quicker than pure tone.
Sealed in epoxy for protection against dust, moisture, and vibration.
Temperature Range: -40°F to +185°F (-40°C to +85°C).
