I got an ES-750 to protect my entertainment system. There are two Tivo's on it and the battery backup feature for preventing those long reboots Tivo's do for a minor power fluctuation.

I don't want the UPS to tell me when power has been lost though. I want it silent, no beeping. Is there any way to do this without installing software on a computer and hooking it up? I really don't want to go through the hassle of installing software and drivers. I am a bit amazed there is no "silent" switch.

Thanks. That is so lame. I'll keep that in mind when I buy my next UPS. It won't be APC if the default is "annoying beep on, and you must install our software on your PC even if the UPS isn't for a PC"

I am very tempted to take this one back because of it in fact.

Once you store the silenced alarm setting within Powerchute, it stores it within the UPS. So if you have a pc, install PowerCHute, disable the alarm notification sounds, and proceed with using the UPS as you intended with your entertainment system.

Ed,

I understand your concern with not wanting to be woken up at 2am to be alerted that power has gone out in your residence. I use the software at home to disable the audible tone as well, however, I think taking a look at it from a different approach may be ideal. Is the UPS your source of power for your alarm clock in the morning? What would occur if you were to have to wake up at a specific time during the week, and your alarm clock, which is not powered by your UPS, powers off due to a blackout, even if it is momentary? I think it would be ideal in this scenario that the UPS wakes you to notify you of a power failure. That would allow you to possibly find an alternate source of power for the alarm clock, or, if power is to be restored within a reasonable period of time, to reset your clock so that you wake up on time.

Yeah. Instead of $50 on a PC one, you should have spent $500 to $1500 to get an AV one so it doesn't beep.

Don't be tricked into the trap of using the PC to try to "fix it" when it does start beeping in the middle of the night either. I've got the software installed on my laptop and had some noise or some overvoltage thing going on at 2 AM one night cause the power is still on and nothing else in the house . The UPS wakes me up. I then hook up my laptop to try to "fix it", then it shuts down my laptop because the software assumes that the UPS is protecting the PC on which it is installed, so it takes me 3 reboots to finally get the PC to stay on long enough to change my sensitivity settings so the situation will not keep happening. In the meantime i had to power cycle the UPS and hence my DVR a couple of times to get it to stop beeping. Preventing hard power cycling of the DVR is why I bought this thing in the first place and it has hard cycled more than anything else in the house so far.

It would be really nice to tell the UPS that the computer is being used only to manage the UPS and doesn't need to be shut down.

I certainly don't mind installing software on my PC to manage this UPS and didn't consider it advertising. I bought it to keep power on my DVR and do not want the extra features of an AV UPS that cost tons of extra money. I like that I can control and configure it with my PC. The cost of the AV centric models are about 10x to PC centric models, so this is almost perfect for me. I just wanted a battery backup.

I just want the software to have the option to not shut down the PC that is connected to it. I know it does not have such an option now. It really works great except that kept shutting down my pc one night when it thought there was a power failure when I had the settings set to stringent (I had either noise or an overvoltage problem, the power was still on). All I wanted to do was reset the settings, turn off the beeping, and go back to bed. It took an hour because my PC got shut down 3 times before I could get it to change the settings. A simple "don't shut down my pc, it is an independently powered laptop" option would be great. The last thing I wanted to do was power cycle the things connected to the UPS, which I ended up doing due it taking so long to change the settings and the UPS battery ran down to 0.

APC AV Black 1kVA S Type Power Conditioner This is the one you have to have to shut off the alarms and it is used for A/V systems sells for 449.00 dollars very nice unit. I use APC on 3 systems and to power my phone and some other equipment and have no problems with the software and the alarms can be turned off and if set up correctly they will not shut down your PC. In my case that is what I want to happen to shut down my equipment properly in the event of a power failure or over voltage. It never fails there is always a glitch in all system and yes I agree there should be a way to turn of the alarms manually.

All the talk of using the software to control the alarms would really be a mute point if there was a 50 cent switch installed to just turn the dang alarms on or off. I'm using my UPS as a backup to a power recliner/lift chair for a disabled person and to run a low wattage lamp if the power should fail. The beeping is very annoying and in my application the UPS will run the things for several hours.

In the grand scheme of things an inexpensive switch would be a cost-effective solution during the manufacture of a product in this price range. Putting it under the battery cover would eliminate accidental changes since it isn't something you'd be changing on a daily basis. If you want to be notified of power failure turn them on, if not turn them off. And to respond to the person who asked if you'd wouldn't want to be notified of a power failure at night so your alarm would go off at the correct time, buy an alarm with a battery backup for $10. sheesh!
