Turnkey’s AlarmBox is a controller for dust suppression equipment. It can be set to alert users when predetermined levels of pollutants are reached or exceeded.

The AlarmBox is compatible with all of Turnkey’s dust monitors and can be set up to provide audio or visual alarms.

There is no requirement for an additional computer but it can be configured to work with computer software via a laptop, PC or mobile device with our free software or Android app AlarmBoxApp.


It connects simply to your chosen device via the AlarmBox’s USB point. When configured with the appropriate software the AlarmBox will automatically detect the parameters being measured by the connected air monitoring device.

How it works

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.

The software and app can be used to create an alarm scheme based on:

  • Dust concentration – any combination of TSP, PM10, PM2.5 or PM1
  • Wind speed
  • Wind direction
