This is how a standard blip on the gadget will work.
It show you that the blip comes once every second.
The following next video clip shows the BH owner how many times the electrical trips occurred.
A very interesting gadget and the cheapest so far.
If my eyes is right the number of times it blips was 12 times.
You can imagine the cost to rush up from your home to this BH to reactivate the electrical system.
Since it cost is pretty low it is wise for every BH to install one.
Reduce the frequency of electrical failure.
Remember if there is no sound your BH is considered dead.
