So I've got 4 of the UPS 350s which have all beeped annoyingly because the batteries are shot in them as they are all 6 years old. BUT I do not need battery backup... I just want to use them as a standard Surge Protector.
I removed the batteries completely and assumed they would see that it's not connected so it shouldnt beep... nope, after 5 days of them all being plugged in and running things, one decides to beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep. So I have to pull it from the wall for a few seconds and plug it back in to stop.
Is there any possible way to use these things without that beeping? Even when they were new they would still act stupid with the beeping.
Do I need to open them all and rip out the speaker on them to fix this or what?
Can you clarify the exact model from the back or bottom of them? It'd show it on a white sticker - something like BE350G or similar. Some units have the capability to disable the beeping for certain situations but I'd have to check once I know the specific model since we have a few generations of 350VA models.
Hi Integraolgist, The unit is cerainly still capable of providing you limited surge suppression without the internal battery installed, however it is not recommended you use the unit in this fashion. The beeping your hearing, is likely resulting from a failed Automatic selftest which occurs every 14days. When it attempts to run the selftest and see's that there is no internal battery, the unit enters a fault conditon emitting a constant tone. The tone is emitted from a small solid state component which is physically soldered to the internal PCB board. I would not recommend altering this circuitry and would rather suggest you replace the internal batteries or procure a suitable surge arresting device.
Thanks for that info. As when we bought all of these the batteries did not last more then just a few months before the "self test" started to go array on all of them... the the fact that the batteries are closer to what a new unit will cost, we're just not going to go the APC route and probably just buy terminator protectors as we did at our other shops and never had an issue.
Thanks for the help.
