4.5.3. Setting / Checking Trigger Level (ANN Sensitivity Level)
Depending on Classic Mode or Enhanced Mode, the trigger level or ANN Sensitivity Level can be set
from 44 to 99 dB in steps of 5 dB. In Classic Mode, the ALARM RELAY will activate at this trigger level,
changing from open contact to closed (factory default) and in Enhanced Mode the ANN Sensitivity
Level will control the SPL dB level which needs to be reached, together with a positive ANN calculation
to trigger a unit alarm.
Activate the MENU switch twice with the magnet-stick. The current trigger level will be displayed
(factory setting is 79 dB for Classic Mode and 54 dB for Enhanced Mode). Activating the UP switch (
▲
)
will increment the trigger level by 5 dB. Activating the DOWN switch (
▼
) will decrease the Trigger
Level in 5 dB increments. Activating the ENTER switch without changes made, switches the unit back
to Normal Operation. Activating the ENTER switch with changes made, will flash “SAVE” on the
display. Confirm the save action by activating the ENTER switch once more. Activating the MENU
switch while “SAVE” is flashing, will discard the save and switch the unit back to Normal Operation. If
ENTER was activated the unit will display “DONE” to confirm that the changes have been saved and
return to Normal Operation.
The operator can change the trigger level and, if desired, move to the next item (Cut-off Frequency) in
the menu structure by activating the MENU switch straight after the change. The change will be saved
at a later stage by activating the ENTER switch at any point in the menu structure. If no switch is
activated for 60 seconds, the detector will return to normal operation without saving the changed
settings.
