Another one for you clever okes out there

So one has a hybrid setup...wanting to have an "alarm" of sorts to tell me when there is load shedding.

1. Most basic solutions I guess would be a relay of sorts with an indicator light - only lights up when Eskom does what it does best.
2. Even better would be a combo light as above PLUS an audible alarm of sorts - something that beeps quite loud when power first goes off, and subsequently beeps at half volume every 10 seconds or so -  with a push-button to "confirm" / stop the beeping.

Any ideas / any standard products out there that offer this functionality?

 

 

buy a small UPS, you'll get your beeping when the mains fails  

I have a few of those silly 600VA (single battery) UPSs 

You are welcome

No charge.
