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 shall be used when the typical application temperature is "high"
compared with the class A1 and A2 algorithms.
14.6 Self Verification
The analogue detectors 430x /440x in NORMAL mode have a built-in self-verification
function. The detector's H/W is always supervised by the detector's S/W and CPU. Every
minute, each detector will receive a question from FT128. If the self-verification function
has detected any fault it will be reported back to FT128. A fault will be activated in FT128
and the following fault message will be shown:
Fault: Detector xx-xx →
FAULT: Detector techn. address nnn ←
14.7 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 FT128 for each detector
individually

. Every value is checked if it is a new minimum or maximum value for that
detector and if so, the value will be stored. At midnight every day a memory will be updated
and the new minimum and maximum sensor values
117
can be read in menu H4/U3 or via
EBLWin.
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 37 and Figure 38.
Note: In order to see the graphs, you must install Microsoft MSChart.exe on your
computer or notebook. The software is to be installed only once in your computer so you
don’t have to do anything when you install new versions of EBLWin. The link to install
Microsoft MSChart as follow:

For this feature to work, the panel must be connected to the laptop and logged onto EBLWin with the USB dongle throughout
the data capture period.

I.e. the min. / maximum sensor values are from the previous day.
