Have you change the battery? Note: Matrix UPS need to be calibrate after changing batteries or reset the Smartcell communication board. to make sure that the UPS would detect that you already replace it with the new battery

Ok, 3-4 years is a much as you can expect from an ups battery so replacement is indicated. The beeps are letting you know the battery is not able to keep up with demand. So either you have recently added to the system or the battery/s failing.
