UPS is constantly quick beeping and shutting down

My UPS is a Fenton Model: P600E SN: 2050301395

It has run for about 12-15 years without a hiccup or a problem.

Was away from the office with the UPS running the computer, Screen, Modem, Standard Speakers;

When I went back the computer was shut down as was the UPS system.

Powered on the UPS and it shut down seconds later with a fast beeping.

Checked out the power supply to the UPS unit and found it was working okay.

Disconnected all the out put lines from the UPS and turned the UPS unit back on, it run for a bout 2 seconds started a fast beeping then turned off.

I Have the user manual for this unit but can't find it at the moment.

Any ideas other than blowing taps over the unit and struggle to buy a new one.

I firmally believe in the saving power of a uPS bsystem.

Here's a suggestion that I received from APC tech support:

Do a "brain-dead reset" (their terminology, not mine).

Unplug the unit (and all devices connected to it).

Disconnect the battery (one terminal will do).

Press and hold the power button for 20-30 seconds.

That's all there is to it! Can't guarantee that it'll work for your problem, but it worked for me, and I had a similar-sounding problem.

I'm having a similar problem. I've replaced the battery, but the ups still turns off on its own. But it doesn't kick over to the backup battery.
