internal buzzer is activated, however it can be muted for a specific time by means of a keypad pushbutton
(see Section 3.1.5).
When gas concentration exceeds the maximum range permissible for the detector (overload threshold), the
following actions take place:
for detectors with catalytic sensors – the detector is locked (its sensor is deactivated and the
detector latches the most recent measurement result). The corresponding LED in the area for
status indication goes on (see Section 3.3.2). To restore normal operation of the detector the
detector must be unlocked from another device connected to the system,
for detectors with other sensors – the corresponding LED in the status area, depicted as . goes
on. The detector keeps working and continues measurements of gas concentration, which is
confirmed by the MEAS. indicator that is still on.
Signalling depending on the concentration of gas measured by the detector:
