SD355T Series Addressable Photoelectric Smoke Detector

SD355T addressable low-profile plug-in photoelectric detectors with thermal element use a state-of-the art photoelectric sensing chamber with communications to provide open area protection and are used exclusively with Fire-Lite’s addressable fire alarm control panels (FACPs). These detectors add thermal sensors that will alarm at a fixed temperature of 135 °F (57 °C). Since these detectors are addressable, they will help emergency personnel quickly locate a fire during its early stages, potentially saving precious rescue time while also reducing property damage. Two LEDs on each sensor light provide a local, visible sensor indication.
