Back-up Alarm Selection 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 effective 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 selected, 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 Alarm®, 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. Tonal vs. Multi-Frequency Alarms Tonal alarms emit sound at a single, predominant frequency resulting in the familiar “beep-beep” warning signal that we’ve all grown accustomed to. Conversely, multi-frequency alarms emit sound at multiple to prove either sound is more effective than the other in a reversing vehicle application. However, there are several points of view that should be considered when deciding which option is best for you.

Tonal - BEEP • The beep-beep sound is a familiar signal that is readily understood as a danger signal. • The sound is more piercing and therefore less likely to be masked by ambient noise such as vehicle engines. Multi-Frequency - SHHH • Shhh-shhh is a newer sound that has been introduced as a warning signal. • The sound is perceived to be more directional. • The sound is perceived to dissipate more quickly outside the danger zone behind the vehicle.

Alarms SAE Type A, B, C, D, E & F Indicates compliance with the relevant section of the Society of Automotive Engineers general requirements for back-up alarms and other audible warning devices. Specific type indicates the dB(A) of the alarm.

General Information CE Indicates compliance with general mandatory European product safety regulations (electromagnetic-compatibility).

R10 Indicates compliance with mandatory European product safety regulations specifically related to electrical products for on-road vehicles (electromagnetic compatibility). IP Indicates level of environmental protection provided by a product enclosure as defined by the European Committee for Electro Technical Standardization. Ingress Protection (IP) ratings are stated as two numbers, the first number relates to protection from solid materials (1-6), and the second number to protection from liquids (1-8). The higher the number, the greater the protection. UL Indicates compliance with a relevant electrical product safety standard as defined by Underwriters Laboratories (UL). UL recognized products are suitable for use on electrically powered vehicles that are themselves covered by a UL standard (i.e. forklifts).

AMECA Indicates 3rd party, independent verification of SAE compliance by the Automotive Manufacturers Equipment Compliance Agency.

Cameras FCC Indicates compliance with the types and levels of radio interference that products can produce or accept without requiring a license. Operation is subject to the condition that this device does not cause harmful interference. RoHS Indicates compliance with European directive restricting the use of hazardous substances such as lead, mercury, cadmium, hexavalent chromium, and six other substances.

RCM Formerly C-Tick. Indicates that a product complies to the EMC requirements established by the Australian Communications and Media Authority (ACMA).
