The assembly also enables checking the detector’s functioning: If a magnet is positioned
near the indicator’s LED indication light, the detector enters an alarm mode.
Additionally, using the TBD-8100C instrument of the TBD-8100R assembly, you can
assess the detector’s signal strength, amplification and type of fault (the letter F appears
in one of the screen’s locations):
a. More than 50% dust accumulation on the detector
b. More than 90% dust accumulation on the detector
c. Signal level is very low or it does not exist
d. Alarm
The most recent alarm of the detector (in case there are several detectors connected
within the same zone).
