Hi. New to the forum, so I hope this isn't already covered somewhere...My parents live on their own. My dad is deaf, but my mom has serious health issues. They will be getting a Lifeline or similar device for my mom to alert a contact if she's fallen or other emergency. However, if my dad is in another room and unaware of the emergency, he is afraid his first indication will be the paramedics breaking down the door in response to the call. Is there a device that he can wear day and night that will also alert him of my mom's emergency with maybe a strong vibration or similar? Thanks in advance.
