Definitely! I have been awakened twice in the middle of the night by the alert tone.
If you can get it to respond to the alert signal it will wake the dead. I read a comment that if the radio is programmed for specific county codes (S.A.M.E.) the radio won't respond. I had my radio set to all specific county codes for my local transmitter and the radio has yet to activate. I now have it set for ANY county to see if it works. There are two jacks on the radio that are not explained in the instructions or on the otherwise excellent videos on YouTube. One jack I assume is for connection to an alert device for someone who is hearing impaired, but no details. I will leave a more detailed review as soon as I verify the alert function. As of yet, I would not entrust my life to this radio.
