Application . <br /> Although photoelectric detectors have a wide range of fire sensing capabilities they are best suited for detecting slow, smoldering fires. <br /> The table below shows six standard test fires used to rate the sensitivity of smoke and heat detectors. The table indicates that no single <br /> sensing element is suited for all test fires. <br /> Edwards recommends that this detector be installed according to latest recognized edition of national and local fire alarm codes. <br /> SIGA -HRS and <br /> SIGA -HFS Rate -of- SIGA -PHS SIGA -IPHS <br /> Test Fire SIGA -IS Ion SIGA -PS Photo Rise/ Fixed Temp.
