The ENFORCER E-931-S35RRQ Retro-Reflective Photoelectric Beam Sensor provides reliable sensing of objects that enter the space between the sensor and reflector, thus breaking the infrared beam. It is suitable for various types of such as detection such as sensing approaching vehicles to open a garage door or outdoor gate, as an entry notification for stores, for measuring parking distances, industrial automation, or an alarm notification, as well as many other uses.

| Trouble | Possible Origin(s) | Remedy(s) |
| Sensor does not detect the object. | 1) Sensor sensitivity is not properly set.
2) Object may have a reflective surface which confuses sensor |
Change the angle of the sensor or readjust the sensitivity setting |
| Yellow LED does not turn on. | 1) Dirty sensor and/or reflector.
2) Reflector and/or sensor is misaligned. |
1) Clean the sensor and reflector with a
damp (not wet) cloth. 2) Adjust the reflector and/or sensor for proper alignment. |
| Red LED lights when object is detected, but no output | No continuity between sensor and alarm
device |
Check cable from sensor to alarm device. Test sensor. |
