Description of a wearable vibrating fire alarm for people with hearing impairments. Designed by an engineering student at the State University of New York at Buffalo, the alarm system comprises a wireless infrared (IR) transmitter and receiver built from MK161 and MK162 kits ordered from ApogeeKits, a standard fire alarm, and a vibrating DC motor. The transmitter was modified and mounted onto the fire alarm in place of the bell. Signals sent from the fire alarm/transmitter are received by the receiver kit which is wired to a DC Samsung a670 vibrating phone motor driven by 4 AA batteries. The receiver kit resides inside an arm band typically used for an iPod, featuring a clear front to allow for minimum IR interference, an adjustable strap, and a Velcro case which makes it easy for the user to change the batteries. Total cost of equipment for building the alarm was 85 dollars.
