Setting the volume and the signalling tone groups following sounder mounting
If the signalling tone and sound pressure level settings must be changed after the device
has been mounted, the sounder must be dead (no-voltage).
Wait more than 15 minutes
before opening the device.
Loosen the 8 housing screws and lift the upper part of the housing slightly. Detach the
connecting cable running from the loudspeaker to the circuit board at the circuit board and
put the loudspeaker part aside. Perform the setting as described above.
Warning:
The programming of signalling tone group GroupF must be performed outside of
hazardous areas only, because the opened device has to be supplied with voltage
during the procedure.
