1. 1. 1. 1. Field research indicates photoelectric smoke alarms exhibit significantly
             fewer nuisance alarms than ionization smoke alarms (1, 2).
         
         
         2. To silence a triggered smoke alarm, about 22% of consumers will remove
             the battery, leaving the alarm inoperable and potentially putting the residence
             and its occupants at risk should a true fire occur (3).
         
         
         Considering photoelectric smoke alarms are determined by industry experts to be
         significantly less prone to nuisance alarm and potential disabling of the batteries
         by consumers, we support and encourage fire service administration and lawmakers
         that are moving toward the use of photoelectric smoke sensing technology.
         
         
         In addition, First Alert aims to reassure all public safety advocates that ours is an organization
         that actively supports our consumers amidst this safety-related legislation.
