Reviews of Reliance Controls THP207 Plug-In Power Failure Alarm with LED

Customer Ratings:

This device works basically as advertised; however, make sure what it does is what you really need before purchasing it.

I bought it to monitor an electrical circuit with a trip-prone GFCI safety device. One outlet on the circuit powers a chest freezer out in my garage. I plugged this unit into an indoor outlet connected to the same circuit. If the GFCI trips, cutting off the power to the freezer and creating a nightmare if the situation remains undetected, the alarm goes off inside.

In my case, this works out perfectly. When triggered, the alarm is just loud enough to attract attention.

There are two significant "catches." First, and as others have noted, the alarm is not very loud. It is about as loud as the beeps of a small alarm clock, or perhaps the more powerful alarm watches. You can hear it fine in a nearby quiet area. You can't hear it through moderately thick walls or from very far away. I can hear it OK inside my single-story house, but I couldn't hear it when I tried connecting it in the garage.

Second, while the unit is fairly unobtrusive, it does tie up an outlet without providing a pass-through socket, and it may interfere with plugging something into the adjoining socket. This could be a problem if you need the socket it occupies, or if you are trying to connect a transformer brick, GFCI plug, or similar bulky plug-in into the remaining socket of a typical outlet.

If these two issues aren't a problem, then this device will do the job just fine.

I bought this hoping it would warn us of a power failure on the circuit to our chest freezer. The light is cute, but the so-called alarm buzzer of 85 dB is a joke. it may be 85 dB if you place it right next to your ear, but from a distance of 20 feet, it is barely audible. to make matters worse, our unit broke in less than 3 weeks. I would not recommend this to anyone; I wish the star ratings allowed an entry of zero stars

Box say 86db, I can't believe it is more than 8.6db. This is junk and I feel as if I was ripped off.

Honest reviews on Reliance Controls THP207 Plug-In Power Failure Alarm with LED

This alarm is a must for anyone with a CPAP machine. It is small and unobtrusive. I no longer am concerned about a power outage. If the power goes off in that outlet, an alarm goes off similar to an alarm clock. There is also a light that goes on at the same time. This is a must for anyone that sleeps with any electrical appliance. Great peace of mind for a small price!

This "alarm" is too quiet. It wouldn't wake up a mouse. It measures 56db @ 12" from the device.

For comparison, the fan on the freezer I wanted to protect is 54db.

It needs to be at least as loud as a cell phone.

Useless for me.
