With a traffic light warning system, the visual lights are clear and require no explanation. The trigger points can be set at specific levels as required. For example, one alarm could be activated when PM10 > 250 µg/m3 AND (PM2.5 > 20 µg/m3 OR PM1 > 10 µg/m3) AND wind speed > 5 m/s.
The AlarmBox has the capacity to store 16 different scripts, which are saved to its flash memory.
Once a preset level is reached, the alarm will activate. Alternatively, it can be programmed to activate only if a level is exceeded for a specific time period. Depending on the requirements of the end user, this could be an audible alarm, traffic light visual system, or it could be programmed to automatically activate dust suppression equipment.
