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-PS Photo Rise/Fixed Temp.
