Question:
Can this unit be set to operate completely silently? No audio alarms?

UPS On: When in Off mode, press and hold for 2 seconds to enter Battery Self-Test mode, then On mode. Manual Battery Self-Check: Press and hold for 3 seconds to temporarily enter Battery Self-Test mode. Mute: When in On/Battery mode, press and hold for 3 seconds.
Liebert Uninterruptible Power Supply (UPS) PSI Editorial Review
The Liebert GXT5 UPS is an impressive device with an efficient 90% power factor, which makes the load a smaller percentage therefore increasing the run time. The device is also silent unless running on batteries or charging. The front panel readouts are basic but get all the needed information and everything else can be obtained via USB. The device is perfect for unexpected power drops, comes with an impressive battery array and is a great brand with quality products. The device has no Wi-Fi capabilities, does not have a sleep mode and its battery life longevity is yet to be determined.
