Smart-UPS products use a beeping tone to indicate various modes of operation. Some customers may want to mute these alarms.
On Smart-UPS models with LED indicator lights on the front panel, you can mute alarms via the Network Management Card or Power Chute Business Edition. The model numbers of these units would begin with SU, SUA, SURT, or SUM. The exact menu location will depend on the specific version of the Network Management Card or Power Chute that you are running. Muting alarms on these units will mute everything except for the Low Battery Signal Alarm, which is continuous beeping for the duration of the Low Battery Signal. There is no way to mute this alarm. You can configure the Low Battery Signal via Power Chute or the Network Management Card. It defaults to 2 minutes.
For Smart-UPS models with an LCD screen on the front panel, you can mute all alarms including the Low Battery Signal. These units have model numbers beginning with SMC, SMT, SMX, or SRT. You can configure this via a Network Management Card, Power Chute Business Edition, or directly from the LCD screen. On the LCD screen, go to the "Configuration" screen and then select "Audible Alarms".
