Polarized Reflective Photoelectric IR Beam Sensor, 33ft, ETL

Model Number: E-931-S33PRGQ

The E-931-S33PRGQ 33ft Polarized Reflective Photoelectric Beam Sensor provides reliable detection of shiny objects that could be missed by a non-polarized sensor.

Polarized sensor is immune to shiny objects: triggers only when correctly reflected light is detected

Sensor does not detect the object.	Change the angle of the sensor or readjust the sensitivity setting
The beam sensor LED will not turn green	Clean the sensor and reflector with a damp (not wet) cloth Apply a coating of RainX™ to the reflector and the face of the sensor to help keep the units clear of moisture. Adjust the reflector and/or sensor for proper alignment
Beam sensor LED lights when object is detected, but there is no output	Check wiring between the sensor and local alarm device
