freezer) on a GFCI (Ground Fault Circuit Interrupter). He warned me that if the GFCI trips, there might be no indication inside the rest of the house that there is trouble,
and I could potentially lose the contents of the freezer before I notice the problem. He also said that to the best of his knowledge, there is no audible alarm available on
I checked around and could not find one, though I did find several rechargeable flashlights that can be set to automatically come on in the case of a power failure. One
such product is available at Radio Shack under the name "Eton American Red Cross Blackout Buddy" (part # 20-019) for $14.99.
The Blackout Buddy has three LEDs at one end and one LED at the other. There is a red switch on the top of the case that turns on the three LED end and an
"OFF/Auto" switch on the side that turns on the one LED end. The three LEDs will only light when the Blackout Buddy is disconnected from AC power and the top cover
switch is turned On. The one LED end is a nightlight and will only light when the side switch is in the "Auto" position and the room is sufficiently dark.
Radio Shack also sells several buzzers that could be attached in place of one of the LEDs. Once complete, when the LEDs light up, the buzzer also goes off.
Some of this project sounds like an advert for Radio Shack. Other than living in the Ft. Worth, Tx area, I have no connection with Radio Shack. I will not be
compensated in any way if you purchase any or all of these components at Radio Shack.
Of course it must be noted that making these changes to the Blackout Buddy will definitely void its warranty.
