My NBN battery backup unit is beeping. Not any of the identified beep codes either. Sometimes it will beep twice every few minutes, but most commonly it just beeps continuously (repeated single beeps) until I press the alarm silence. This also only silences the alarm temporarily (30 seconds to 30 minutes at best).
I have replaced the battery with 2 brand new batteries to see if this was the issue, regardless of the fact that the replace battery light is not lit.
This is also resulting in intermittent loss of Internet and phone, meaning I am having to use extra mobile data on my phone.
The beeping and alarm silence not working is the biggest annoyance as I have a newborn baby!
Please help!!
