Back-UPS Pro 1200 randomly beeping

[BillP]

Symptoms:

• 3 (sometimes 2) short beeps, every 30 seconds
• system fault blinking with NO fault number displayed, just the usual Watts display
• AVR blinking but low/high input icons are NOT lit
• does this for 20-30 minutes and then stops
• seems to happen every day around the same time (noon and evening)

This is quite annoying as the beeps can't be muted. Other than that the UPS works correctly.

Hi Luper,

Could you provide us with the exact model and serial number of the unit?  A few more general questions:

How is the power quality in your area?

Have you ever replaced the battery?

What are you connecting to this unit and what is the total load percentage?

Are you using any software with this unit?

Is there anything else that occurs concurrently during these same intervals that this beeping begins?

Did this just begin recently and did any major event occurs at the inception of the issue?

[BillP]

Model is BR1200G-FR, S/N 3B1437X01879

Power quality is OK.

Battery was never replaced, unit was bought in january.

I connect a plasma TV, 2 preamp speakers, and a satellite decoder. Load is around 20%.

No software.

Nothing else occurs during the beeps. Also note that they occur indiferently wether the TV is on or off.

It begun maybe 3 weeks ago.

Are you sure it is not 4 beeps every 30 seconds?

I would recommend unplugging the unit from utility power, unplugging the equipment plugged into the unit, removing the battery, and holding the power button for 20 seconds.  Then reassemble the unit and power it back on and observe its behaviour.

[BillP]

Yes, 3, not 4.

I will try your recommendation, thanks.

[BillP]

It didn't help, problem still persists.

Please note that it does 3 *short* beeps, shorter than the 4 ones you get when on battery power.

Luper,

As this is a unit used in France, I would advise calling into your local support for further troubleshooting.  From what you described, this may be an issue/indicator that is specific to the French unit.

Hello,

Luper, have you found a solution ? Mine go exactly the same way : 3 Beeps every 30s, "AVR" and "Go Manuel" ( Systeme Fault) blinking without Fxx.

Hello, 

I've exactly the same problem like you, with a French model like Luper. This is a new one that I installed yesterday, it works for 1 hour with no problem, and after it make 3 Beeps every 30/40s, with "AVR" and "SystemeFault" blinking and no number of error (no Fxx)

How can I do ? 

Thanks, 

Benji

Hii, you can do it very easily don't worry about that.

[BillP]

Since the support has no answer, I ended opening the APC and removing the beeper from the PCB with a pair of pliers (a black cylinder with a hole on top), no more beeps and it works (apart from the beeps it always worked fine). 

(and sorry but "contact your country's support" is not an acceptable answer from a multinational company, you should have contacted them yourself, I already did my part of the job by investing time in reporting an issue)

Hello Luper, 

Thanks for your response 🙂 

I contacted my country's support, and they sent me a new one immediately, because they had never seen this problem. 

I received the remplacement model two days later, it was perfect !

Have a nice day,
