SETTING OF BUZZER SUSPENDED PERIOD
The abnormality is noticed again by sounding of the buzzer after certain suspended period (buzzer
recovery timing) if the alarm status continues even after the buzzer is silenced by depressing the buzzer
stop key (BUZZER). Always set the buzzer suspended period to avoid the wrong recognition of alarm
status
Setting range of buzzer suspended period:
Between 10 and 60 minutes with 10 minutes interval (display of setting; between 010
and 060) or no recovery (display of setting; 000)
Initial setting (factory setting): 30 minutes (display of setting; 030)
The buzzer does not recover once the buzzer is silenced by depressing the buzzer stop key (BUZZER)
when the suspended time is set to 000. However, the buzzer operates if other alarm status is detected.
Example: Change the suspended period to 20 minutes from 30 minutes
