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. More articles from Brigade Electronics Plc: |
