The AD365(-IV) is an addressable, multi-criteria detector incorporating photoelectric, thermal, and infrared (PTIR) detection principles. Advanced algorithms maximize the advantages of each sensor type creating a more robust detection strategy that rejects nuisance sources but still responds quickly to real fires. Available in both white (LiteSpeed protocol only) and ivory (CLIP and LiteSpeed protocols). Compatible with ES-50X & ES-200X addressable fire alarm control panels.
