Why is this weird? Fire alarms come in a variety of styles to accommodate people who are visually or hearing impaired. Our hospital has the most obnoxious strobe lights that light up when the alarm system is activated. If I were deaf, I would feel safer to know that I wasn't missing out on the fire alarm. They also make beds that vibrate so if that deaf person is asleep, he/she doesn't miss out on the strobe light and die in a fire.
