Reversing and Warning Alarms

Why Reversing and Warning Alarms?

The rear blind spot 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.

Reversing Alarm, BBS

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.


Heavy duty

For plant, quarry and construction machines or environments with high ambient noise. Our heavy duty back up 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
  • Heard through ear defenders

bbs-TI 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 when the nearside indicator is activated, informing the cyclist or pedestrian of the vehicle’s intended turn and allowing them to take appropriate action.

  • Visual and audible side turn warning for vulnerable road users
  • Synchronises bbs® sound with the vehicle indicator flash
  • No language barrier from traditional speaking alarms
  • Built-in mute function

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

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.

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