Siemens DLR1191 Linear Smoke Detector Reflector (Long Range)
Product Code: DLR1191
DLR1191 is the retroreflector used by the linear smoke detector in long-range applications. Retroreflectors return light falling on them parallel to its direction of arrival; therefore they do not need to be mounted at exactly perpendicular angles to the light beam. This feature significantly simplifies installation and prevents the system from losing alignment with small angular deviations caused by building movement.
