White Noise Reversing Alarms

Why White Noise Reversing Alarms?

The rear blind spot is a huge problem regardless of the vehicle or machine – reversing vehicles account for a quarter of all workplace deaths. With 90% of these reversing accidents occurring off-road (loading bays, lorry parks, quarry sites, warehouses etc.) there has never been a greater necessity to carry out effective risk-assessments of reversing processes.

A white noise reversing alarm is a device to warn anyone in a vehicle’s path that it is moving backwards. Reversing beeper alarms were introduced to Europe in the 1970s and provided a vital step forward in safety.

Brigade Electronics – at the forefront of reversing alarm technology since introducing the first reverse alarm models addressed the problems of effectiveness of alarms in urban and work environments.

Brigade bbs-tek® Alarm

Instantly Locatable Sound

Our patented White Sound® reversing alarms are the safest reversing alarms in the world and do not cause a noise nuisance. Simple to fit and relatively inexpensive, the ‘ssh ssh’ white noise can be heard extremely clearly in the danger zone, even when wearing headphones or ear defenders or for people who have hearing difficulties. Yet the sound dissipates quickly outside the hazard zone, lessening the environmental impact and the likelihood of noise complaints.

Heard Only Where it Matters

White noise reversing alarms use broadband frequencies, giving greater directional information to the ear. This means the sound is instantly locatable – a huge leap forward in terms of safety because even a split-second’s confusion can result in serious injury or death.

Pioneering Reversing Alarms

Over the decades reversing beeper alarms became standard on almost every commercial vehicle. However, concerns began to be raised about their effectiveness in an urban environment or on a work site, where several alarms could sometimes sound at once, making it difficult to establish where the danger was coming from. Additionally, the piercing beeps caused by high-pitched tonal alarms generated countless complaints about noise pollution.

The answer has come in the form of Brigade’s bbs-tek® White Sound® Reversing Alarms – a revolutionary new generation of alarms that have rapidly superseded the ‘beep beep’ products of the past.

Our bbs alarms are covered by the following patents: AU2007200517, EP1289798B2, CN100488807C, JP4798474B2, NZ522190, GB2345392C, USRE44912

Awards & Endorsements

Brigade’s bbs-tek® White Sound® reversing alarms are endorsed by PIEK and the Noise Abatement Society and have been awarded the Quiet Mark for their environmental benefits.

bbs-tek® provides a superior warning for those in the danger area. It is more easily located and less likely to experience interference from reflecting surfaces than narrowband back-up alarms.

The Reversing  Alarms Range

BBS-102/107 Heavy Duty Alarm
BBS-102/107 – Heavy Duty


For plant, quarry and construction machines or environments with high ambient noise. Our heavy-duty reversing beeper alarms operate in the harshest environments keeping ground workers safe. The multi-frequency sounds can be heard through ear defenders – a huge advantage over tonal alarms where a single strident tone is blocked out.

  • IP68 rating
  • Can be heard while wearing ear defenders

Brigade’s bbs-tek smart reversing alarm continually adjusts to 5-10 decibels above the background noise level, making it ideal for environments with varying levels of noise.

  • Continually adjusts to 5-10 decibels above ambient noise level
  • Ideal for environments with varying levels of noise
Brigade Turn Indicator
Turn Indicator Warning Alarm

Mounted to the side of the vehicle, the bbs-tek® turn indicator alarm synchronises an audible warning with the vehicle indicator lights. This means when the nearside indicator is activated, an alarm informs cyclists or pedestrians of the vehicle’s intention to turn and allows them to take appropriate action.

  • Visual and audible side turn warning alerts for vulnerable road users
  • Synchronises bbs® White Sound® technology with the vehicle’s indicator flash
  • No language barrier compared to traditional talking alarms
  • Built-in mute function

bbs-TI complies with regulations and legislations that require an ‘audible vehicle manoeuvring warning’ to alert vulnerable road users when a vehicle is turning, including Transport for London’s Direct Vision Standard.
