*The limit values approx. correspond to the concentrations in ppm for hydrogen and carbon
monoxide. However, as the particles to be detected are often present as aerosols, the limit
values should rather be considered as characteristics without dimensions. In addition, the
function for automatic zero-point adjustment leads to a discrepancy between parameter and
actual concentration.
Zero-point adjustment
To prevent incorrect displaying due to sensor aging, the “Standard” basic configuration fea -
tures sliding zero-point adjustment of the sensor signals. However, the longtime constant of
this zero-point adjustment of
≥
6 also hides slowly increasing signal backgrounds.
Smoldering fires that develop over a timeframe of days, cannot
be detected in the “Standard” basic configuration!
4.1.2.2 Basic configuration “Extended 1”
In the “Extended 1” basic configuration, the following limit values are set as default during
factory configuration.
