Alarm level 

When the device is switched ON, it starts to measure with the following 
regular settings: regular Alert and Alarm levels are based on measurements 
carried out in Sintrol test laboratory. Due to this, it is recommended that the 
user does a new setup either manually or using auto-setup procedure. Manual 
setup is done by setting new suitable values to the L1 and L2 functions. Auto-
setup procedure starts automatically when button wire (green) is connected to 
the power supply minus (-) button. Both functions (and other detailed 
information about setting and changing measurement parameters can be 
found in the software manual. 

Factory default for alarm levels: 

Normal level  

 

1000 - 2000 units in clean office air 

 

 

Alert level   

 

1 000 000

 

 

Alarm level   

 

4 000 000

In normal indoor environment Dumo signal level should stay under 5000 at 
the most of time.  

Ambient monitoring and ambient dust concentration level is always strongly 
depenpending of measurement environment. Because of this it is strongly 
recommended that user set alarm levels always in new measurement location 
or environment 

In practise there are three ways to do dust monitoring with Dumo: 

- The simplest way is to monitor concentration level by using indicator LEDs. 
In this type of monitoring, only power supply is needed.  

- The second way is to do monitoring with RS485-terminal. When using 
RS485 terminal, it is possible to monitor data on-line on a PC screen. In this
