INFRA Alarm Beacon is for example used to warn machine operators when piling, sheet piling or compacting both in terms of vibration and noise. The alarm level can be set to a percentage of the trigger level (from 1 to 99%) — after each interval period the maximum value is compared to the alarm level and if the value is higher the alarm beacon flashes. It can also be used for high levels when blasting. In this case the alarm level can be set between 100 and 1000% of the trigger level and the beacon flashes directly if the alarm level is exceeded.
