  • Page 2: Smoke Alarm Limitations And Functions

    SMOKE ALARM LIMITATIONS AND FUNCTIONS There are three basic smoke alarm types: IoPhic , Ionization and Photoelectric. ® IoPhic is an ionization alarm containing a patent-pending Universal Smoke Sensing Technology. ® IoPhic alarms are very effective at detecting fast flaming fires and also respond very quickly to slow smoldering fires - up to 87% faster than the maximum allowable alarm limit (UL217 Smoldering Smoke Test on 5/26/2010, Underwriters Laboratories Project #09CA38078).
