Trying to keep ups from shutting down computers.

We recently purchased the BN600MC to use at work.  We have three computers connected to it .  Two of the three are running security camera software on them and the other one runs software for automated credit card machines.  We have issues with the power going off for a second then back on.  The problem is that we don't want the ups to shut down the computers at all but just to keep them running for that second or two that the power goes off.  Last week the power went off one time and apparently the ups shut down the computers.  We don't want that to happen as we lose our ability to have our cameras and credit card machines running . This is at a location where there usually isn't anyone there to turn them back on so we don't know they are off until we either try to connect to them remotely or actually go to the site.  I am wondering what I need to do to keep the computers /ups from shutting down.  I can understand if it is a prolonged outage but our issues is the power going out for a second.  Any help/suggestions would be appreciated.  Thanks

Although I am not sure exactly why your BN600MC is dropping power, it may be that the three computers are overloading that specific UPS.  Also, for mission critical applications such as credit card and security camera applications, I'd really consider a more robust UPS from, say, the SMT or SMX product lines.  More expensive for sure but certainly worth the peace of mind they would provide if you really have to keep the power on.

I agree with BlueSky. If the equipment is mission critical I would suggest a more robust UPS like a SMT or SMX.

To answer the question why the systems powered down the leading causes are

1 UPS is overloaded

2 the battery is not connected properly

3 the equipment is plugged into the surge only outlets instead of the battery/surge outlets

Thanks Blue Sky & Bill P for your replies.  I will check out those other products.   I did find another post for someone that had a similar issue.  Their "fix" was to remove the data cord from the ups and that way it won't be able to send a signal to turn off the computers.  I tried that yesterday and it does work, but we're losing the benefit of the software.  At least that will work for the time being . 

Also a side question.  Aren't all of the outlets on the ups battery ones or only certain ones and if so how would we be able to tell the difference ?  Thanks again for the help !

I believe 4 of them are battery/surge protection and 4 are surge only protection.  The designations should be imprinted on the housing of the UPS as to which ones are which.  Just make sure your loads are plugged into the battery/surge side of the UPS and that the UPS can support all three of the computer for the length of time you need.  The BN600's rating is 360 watts and most computers are probably at or over 120 watts so your load may be close.

Thanks Blue Sky.  I'll check to see which ones are what with it.  I knew it was close as far as the wattage goes.  Thanks again for the help.
