UPS with no audible alarms

[Ramsubra]

I'm looking for a low-capacity (mainly for my Modem) to run unobstrusively when on battery. Most UPS have non-configurable audible alarms when on battery. Let me know if you know of any products (around 500VA or even lesser) which fit this requirement.

You can try out the "lansafe software" which is having the ability to disable the alarm of the UPS. So download this software by making a Google Search about the download of lansafe software and then try out the same on you system. After installing the same go to the system configuration and select the Silence UPS Alarm.
