System Sensor BEAM-1224S Reflective Beam Smoke Detector They have one built-in signalingSystem Sensor Model BEAM1224 is a four wire conventional reflected beam smoke detector, which is uniquely suited for protecting open areas with high ceilings, where other methods of smoke detection are difficult to install and maintain. It is to be used with UL Listed compatible control panels only. An advantage of this single ended reflective design is that it is much easier to install than the dual ended projected beam detectors.
