When wind speed thresholds are reached the siren and lights are triggered to notify anyone on site of dangerous wind speeds and gusts.
The magnetic mounting on the rubberised feet have a 35 kg total pull force making it strong and secure to attach to a structure.
The siren unit has loudness info as following : 95 dB(A) at 1 m
The WC logger and alarm box have 3 alarm states:
Wind speed is below the amber threshold
No lights or siren active
Wind speed is above amber threshold but below red
Amber light flashing
Wind speed is above red threshold
Red light flashing
Siren sounding (if switched on at alarm box)
The WindCrane logger's alarm outputs update every second (at the same time the display is updated) so it is possible for the alarm box to momentarily activate with a gust, and then deactivate as the wind drops again.
