6.6 Flash Rate
The flash rate is configurable at 0,5Hz and 1Hz. The flash rate impacts
the light intensity and therefore the coverage volume according to
EN53-23.
1Hz flash rate is equal to one flash every second. 0,5Hz flash rate is
equal to one flash every two seconds.
The table below shows the flash rates (Hz) for different VAD intensity
settings for white and red visual alarm devices.
