It's loud enough to hear in the next room, it has an on/off switch, a test button, auto-reset (if the power flickers, the alarm doesn't stay on), a long heavy duty extension wire, a piggy-back plug, and all of the hardware required to mount it. The alarm is powered by a 9-volt battery when the power turns off. These things are more expensive than you would think. After searching around for a while I found this appeared to be the best value and it was exactly what I hoped for. The problem with the other brands typically is that they are not loud enough. It would be nice to have one with a low-battery alarm or a battery re-charger. The same manufacturer makes three different models: [...] Review: Perfect Alarm!! - This little guy performed as advertised - a loud alarm when the power goes off. It is a problem, however, if what you are protecting does not reset automatically. This guy's alarm got turned off when power is restored. I my case the item I was protecting does not automatically reset. I went to CSH's web site & found they had a unit which is exactly like this one except it has to be reset manually (a button on the face does the trick). I sent this one back and for about $5 more got the manual reset version. It works great!! ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 122 Reviews | ## Images ![Failed Circuit Alarm - Image 1](https://m.media-amazon.com/images/I/61onLuKmPsL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works As-Advertised *by M***T on February 17, 2011* I use this for my garage freezer because the ground fault keeps tripping, spoiling the contents of the freezer.

On 28 July 2009 we received some very heavy thunderstorms that tripped a ground fault circuit breaker on the circuit the garage freezer was plugged in. We could hear the alarm even though we had a DVD movie playing somewhat loudly. We had no indication that there were power problems as the lights never flickered in the main part of the house. Without this alarm, we would have gone to bed and most likely not even have noticed the unit had no power for nearly 24 hours or more. Very handy device as it prevented a recurrence of a food loss we had earlier this year due to weather. We had just stocked that freezer the day before the storms hit. We have had two losses of food stuffs over the past several years when the circuit breaker on that unit tripped. This would have been the third as we don't often go into that freezer and the first sign that there is a problem is the water from the unit defrosting. As I mentioned above, we could hear the alarm within the house clearly enough to alert us that the power had failed on that circuit. The alarm is piercingly loud when in the same room - probably on par with a smoke alarm though the alarm on this unit is a steady tone. So, well worth the money...it basically just paid for itself the other night just a couple of weeks after we received the unit. Which by the way, was delivered as promised, on time. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/3874668-failed-circuit-alarm](https://www.desertcart.pt/products/3874668-failed-circuit-alarm) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-18*
