To the 23 million hearing-impaired people in the United States, a smoke alarm’s siren might not be discernible.
Two new smoke alarms for the hearing impaired feature high-intensity strobe lights that flash about 60 times per minute when the alarm is triggered. Suggested retail price is $79.99. The Fyrnetics alarms (models SL177 or SL1771) are available in hardware stores, home centers or from Fyrnetics Inc., 1055 Stevenson Ct., Suite 102W, Roselle, Ill. 60172.
