On power flicker I must shutdown

[Suchapaintopostonequestion]

When the power flickers (less than a second), everything keeps running except the UPS alarm keeps buzzing.

I do not lose any work which makes me happy, but the alarm will not shut off until I turn the UPS off, and then back on.  I have the 450 model.

Am I pushing the button wrong?  IS there a setting to ONLY ALARM WHILE the power is off?

I’m not sure if this is the exact UPS model you’re speaking about if not let me know. But if it is you can (Quick Mute) the alarm by pressing the power button for less than 2 seconds.
