SETTING OF ALARM BUZZER RECOVERY
The alarm buzzer recovers and notifies the abnormality again after preset period (alarm buzzer recovery
time) if the same alarm status is continued after the alarm buzzer is stopped by pressing the alarm buzzer
stop key (BUZZER). Always set the alarm buzzer recovery time to avoid the false recognition of alarm
status.
 Settable range of alarm buzzer recovery time:
10 minutes interval between 10 and 60 minutes (setting; between 010 and 060) or
No recovery (setting; 000)
 Initial setting (at factory): 30 minutes
The alarm buzzer never recovers once the alarm buzzer is silenced by pressing the alarm buzzer stop
key (BUZZER) if the alarm buzzer recovery time is set to 000 (no recovery). Nevertheless, the alarm
buzzer sounds when other alarm status is detected.
Example: Changing the alarm buzzer recovery time to 20 minutes from 30 minutes.
Following shows an example. Change the setting as necessary.
