Reversing and Warning Alarms

Why Reversing and Warning Alarms?

The rear blindspot is a huge problem regardless of vehicle/machine with reversing vehicles now accounting for a quarter of all workplace deaths. With 90% of 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.

Reversing alarms are devices to warn anyone in a vehicle’s path that it is moving backwards. Beeping alarms were introduced to Europe in the 1970s. They provided a vital step forward in safety, yet over time they have been shown to have a number of inherent issues; specifically concerning their environmental impact, but also in terms of safety – the exact reason they were introduced in the first place. There is now a much better alternative.

Instantly Locatable Sound

bbs-tek® multi-frequency reversing alarms use a wide range of White Sound® frequencies. This enables the listener to instantly locate where and what direction the sound is coming from. The broadband sound also gives workers wearing hearing protection devices (HPDs) and people with hearing difficulties a better chance of hearing the alarm.

Heard Only Where it Matters

bbs-tek® White Sound® reverse alarms create a “ssh-ssh” sound which is gentle on the ear and dissipates quickly, meaning the alarm can only be heard in the danger zone.

Why choose bbs-tek® over beeping alarms?
bbs-tek® White Sound® alarms Tonal ‘beep beep’ alarms

Effective danger warning? Yes Not always

Alarm sound quickly located? Yes – directional sound Unreliable and confusing

Heard where it matters? Yes – only in hazard zone No – an area at least 30 times greater than the hazard zone

Effect on workers? Treat sound with respect More likely to zone out and ignore the sound

Heard by those wearing ear defenders or with hearing impairment? Likely due to multi-frequency Less likely – single frequency

Eliminates noise complaints? Yes No – sound too piercing


Quieter, Yet Safer

The sound from bbs-tek® subsides quickly outside of the danger zone, meaning the alarms do not cause noise-nuisance and thus eliminating noise complaints.

Furthermore, with its multi-frequency range, White Sound® alarms can operate effectively at 5 decibels lower than a conventional beeping alarm.

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

bbs-tek® alarms are approved for night-time deliveries by Piek.

All bbs-tek® White Sound® warning and reversing alarms have a lifetime guarantee.

Quiet Vehicle Sounder

Electric and hybrid vehicles are silent at slow speeds and are often in accidents with pedestrians who do not hear the car approaching. The QVS uses a mix of Brigade’s bbs-tek® White Sound® frequencies and tonal frequencies to ensure noise pollution is kept to a minimum and that the sounder is only heard in the danger zone.

SMART bbs-tek®

Our patented white sound reversing alarms aren’t just the safest alarms in the world due to their instant locatability and directional sound, but with the inclusion of our self adjusting models, they’re also the smartest. bbs-tek smart reversing alarms continually adjust to 5-10 decibels above the background noise level, making them ideal for environments with varying levels of noise.

  • Continually adjust to 5-10 decibels above ambient noise level.
  • Ideal for varying environments
