Troubleshooting
| Sensor does not detect the object. | • Check the sensor’s alignment. • Readjust the sensor’s response time. |
| Alarm LED will not turn ON when the beam is interrupted | • Clean the sensor and reflector with a damp (not wet) cloth. • Adjust the reflector and/or sensor for proper alignment. |
| Alarm LED turns ON when object is detected, but there is no output | • Check wiring between the sensor and local alarm device. |
| Alarm LED is continuously ON | • Check the sensor’s alignment. • Check for any objects between the sensor and reflector that may be causing false alarms. |
| Alarm output becomes erratic in bad weather | • Check the sensor’s alignment. • Readjust the sensor’s response time. |
| Frequent false alarms from leaves, birds, or other objects | • Readjust the sensor’s response time. • Change the sensor’s location. |
