The algorithm is as follows:
Fire alarm level is 74° C.
Pre-warning level is 64° C.
Heavy heat alarm level is 90° C.
The "Class B S algorithm" can be used when the application temperature is "high"
(compare with the "Class A1 an A2 S algorithms).

Self verification
The Analogue Detectors 430x / 440x in NORMAL mode have a built-in Self Verification
function. The detector's HW is always supervised by the detector's S/W and CPU. Every
minute, each detector will be polled from the CIE to detect faults. Any faults will be notified
on the CIE with the following fault messages:

Minimum / Maximum sensor values
To find out how the environment is, where an Analogue detector 33xx / 430x / 440x in
NORMAL mode is mounted, the minimum and maximum sensor values can be studied.
The sensor values are continuously picked up and evaluated by the Control Unit (CIE) for
each detector individually. Every value is checked if it is a new minimum or maximum value
for that detector. At midnight every day, a memory will be updated and the new minimum
and maximum sensor values can be read in menu H4/U4
For Analogue smoke detectors the minimum and maximum sensor values are shown as
XX.X % (obscuration) per meter.
For Analogue heat detectors the values are shown as XX°C.
To access the minimum and maximum sensor values in EBLWin, right click on the sensor
and choose "Show Sensor Values..." in the context menu and it would bring up its sensor
log displaying in graphical or tabulated form, Figure 39 and Figure 40.
Note: In order to see the graphs, you must install Microsoft MSChart.exe in your computer
or notebook. The software is to be installed only once in your computer. The link to install
