Reversing alarm is self-adjusting
December 1st 2007

Designed to improve the safety of employees in warehouses is a vehicle reversing alarm introduced by Brigade Electronics.

Self-adjusting bbs-tek backalarms take the guesswork out of sound pressure level selection.

This makes them suitable for vehicles and mobile plant in areas with widely different ambient noise levels, where a fixed volume alarm might be too quiet in loud environments or too loud in quiet locations. The intelligent device measures, through digital sound sampling, the ambient sound pressure level and then adjusts the alarm to maintain just 5 to 10dB louder.

A small microphone measures and continuously adjusts the sound pressure level.

Alarms use broadband sound, commonly known as 'white sound' which is locatable and localised to the danger area.
