When a UPS audible alarm is active, pressing and releasing
the main ON/OFF button will silence the active audible
alarm, whether utility power is present or not. Once the

alarms—except for low battery or overload conditions—will
remain silenced until a new alarm condition is detected.

seconds or the UPS will shut down.
