Power Return Alarm, Briidea Utility Power Back on Alert for Generator, Loud Siren with LED Indicator

Our power line is 220/240 VAC, 50 hz, while the item operates with 120 VAC, 60 hz

Works as intended. It's LOUD like a fire alarm. If you are not comfortable working inside an electrical panel you should definitely call an electrician. The installation is not for the average person.

Works well. Easy to install. Very loud signal.

The instructions in the box say that the max voltage is 120V, although this had not been mentioned in the advert. I guess this is for the USA domestic market reasons. However, before returning it, I tried it on our 240V supply (the UK domestic voltage) and it worked fine. It’s easy to mount on the wall with the sticky pads supplied. I would have preferred to use screws but this would have required taking the unit apart to use the backplate holes. Once mounted on the wall, installation is very easy. Overall, a great little unit but the supplier could perhaps clarify in the advert that it works on 240V.

Got this alarm to warn when power came back on in an interlocked main panel generator setup. Works very well for the task. When power comes back you will know it, the siren can be heard throughout the house. Being in the same room as it is quite literally deafening until you turn it off. Installation is simple. Mount the device near your panel. Run the antenna into the panel and wrap it tightly around one of the hot legs you want to monitor in you panel. Use a zip tie or electrical tape to hold it in place and tightly coiled. There is a sensitivity adjust if needed, but my setup works fine with the default setting.

Installed without any issue. Power has not gone out since, so I cannot confirm sound or operation.
