UPS beeping

[Offcall1]

Our AT&T Battery backup beeps intermittently with variable intervals and beep durations without any apparent disruption to our house electrical supply. It's worse at night. No othe UPS goes off nor do any other sensitive electrical items (like our clocks) indicate any electrical disruption. We've replaced the AT&T UPS twice and changed the location to a different room. Same problem. Any suggestions on diagnoss and cure?

The only suggestion I can think of is for you to tun off the audible alert on the UPS.  There may be soimething going on with your home electicity that the UPS is detecting as a problem.

Your battery is probably weak. Change your battery (12V, 7.2-7.5 AH).

The battery has a battery?

Or, the BBU itself is taking a dump. I would think if it was just a "replace battery" warning the "beep code" would be the same every time.

If you have had the unit more than 2 years than it is probably a battery issue, the older black belkin units have know issues that lead to battery pack failure after just two short years.

The unit is also very sensitive as to where you plug it in, make sure it is plugged directly into the wall plug. Sometimes the unit switches to battery power unnecisseraly when plugged into a powerstrip or surge protector.

If it happens are a regular time every other day than chances are it is a failing battery pack. The unit does a self test every 48 hours I believe and if the battery pack is going out then the beep occurs to let you know it is failing. I would highly suggest getting it replaced as soon as possible, once the battery pack is completely gone the unit will shut down and you will lose service completely during self tests until you physically reset the unit.

If the unit is under 2-year old you call At&t they will transfer you to Belkin's corporate service so Belkin can get you a new grey replacement unit as part of the standard warranty (no charge).

If it has been longer than 2 years than you can buy a replacement battery pack on Amazon (or your choice retailer) for about $30. Or (as I did) complain to At&t and threaten to cancel service, they will make sure belkin gets you a new unit.

Thanks for the suggestions. The battery should be new since it was installed just last week. Someone suggested it may be a nearby outlet that is poorly grounded. We turned off a nearby outdoor motion sensing spotlight and believe it or not, no beeping. Since I installed the light, it may not be fully grounded. That may have been causing enough flux in the house current to trigger the sensitive UPS. Or it's just magic. Either way.

What type of bulb? Does it do it even during the day when the fixture should be disabled by the photo sensor?

If it is a CFL bulb, that could be the problem. CFLs do not do well with solid state switchs like you'd find in photo/motion sensors. They do not shut completely down and will create noise on the circuit.
