8. Visual Alarm Warnings
The dBadge2 has the ability to define colour coded and LED visual alarm warnings (as
selectable in Section 7.11) based on up to two source data parameters (LAS, LAeq<LCPk,
LZPk, LAVG, TWA, Projected TWA, Lepd, Projected Lepd, LEX8h, Projected LEX 8h). Lower
and upper trigger levels may be specified for each alarm.
When a data parameter has been specified as an alarm source, the parameter will be shown
in a green font for levels below the lower limit. Above the lower and upper trigger levels the
Alarm parameter will be displayed using yellow and then red coloured fonts respectively as
shown. It is recommended that the display is always on to take full advantage of this facility
(see Section 7.4).
The dBadge2’s high intensity LED also flashes blue at a slow rate when a lower level
exceedance is active and at a fast rate whenever an upper level alarm has been triggered.
dBadge2 connects to the Airwave App using
Bluetooth® low energy. This may be permanently
disabled using the Upgrade Utility supplied and this
screen will no longer appear as an option. Press the
right ‘R’ key to accept or left ‘L’ key to change.
To prevent inadvertently clearing the memory, the
keys are reversed i.e. Press the left ‘L’ key o accept
and the right ‘R’ key to decline but there is an
additional screen to check that you wish to progress
since once cleared all stored runs will be lost.
To select a timed run (rather than starting and
stopping a run manually) press the left ‘L’ key to
select fixed or programmable timers. The latter are
set using Casella Insight data management
software which will start and stop the dBadge2
automatically whilst the fixed timer will halt a run
after 8 hours, initiated manually as per Section 6.3.
These final screens provide an opportunity to cycle
back through the configuration menu or proceed to
the start-up screens as per Section 6.1.
