IPDL-D-11/4R Linear Beam Smoke Detector

IPDL-D-11/4R monitors smoke along an optical beam between the transmitter and the receiver: a single pair covers an area that would otherwise need dozens of point detectors. This is the standard solution for warehouses, sports halls, atriums, workshops and any space with high ceilings, where smoke rises and disperses and servicing detectors overhead is costly and awkward.
