SD355 Series Addressable Photoelectric Smoke Detector

SD355 addressable low-profile plug-in photoelectric detectors use a state-of-the art photoelectric-sensing chamber with communications to provide open-area protection, and are used exclusively with Fire-Lite® addressable fire alarm control panels (FACPs). 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.
