ECCO Multi-Frequency Back-Up Alarm

12-24 Volt | 102 db(A) | Surface Mounted Reverse Alarm

The ECCO Back-Up Alarm model number EA7020, is a Multi-Frequency back-up alarm that provides a solution to potential noise pollution created by back-up alarms in confined or densely populated work areas. It is this function that aids in 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 4,000Hz so that the sound is perceived to dissipate more quickly than a conventional pure-tone alarm.

Back-Up Alarm Selection : What are the options?

There are several decisions to be made when selecting a back-up alarm.

First, you have the choice between a tonal alarm and a multi-frequency alarm. Industry experts have suggested either can provide an effect warning, and each has its merits as described below.

Second, you must choose an alarm with the appropriate sound pressure level (SPL). OSHA requires a reverse alarm to be audible above the surrounding noise level. If you know the ambient noise level and it remains reasonably constant, then the appropriate fixed dB alarm can be select, whether tonal or multi-frequency.

The key is complying with the requirements of OSHA while selecting the lowest SPL alarm possible so as not to create a noise nuisance. Fortunately, ECCO pioneered another solution - the Smart Back-Up Alarm, which is available in either tonal or multi-frequency. Smart Alarms monitor ambient noise and automatically adjust their output to 5dB above that, satisfying OSHA's requirements. Smart Alarms are the perfect solution for work sites with inconsistent noise or varying noise levels.
