Large Reflective Photoelectric Beam Sensor, 50ft

E-931-S50RRLQ

Large Reflective Photoelectric Beam Sensor, 50ft

The ENFORCER E-931-S50RRLQ 50ft Large Reflective Beam Sensor provides reliable long-range sensing of objects that come between the sensor and reflector and break the infrared beam. Its lensed optics reinforce beam strength and provides excellent immunity to false alarms due to rain, snow, mist, and minimizes false alarms from falling leaves, birds, etc. It is suitable for various types of detection such as perimeter security, opening a garage door or outdoor gate for approaching vehicles, measuring parking distances, industrial automation, entry notification for stores, alarm notification, and much more.

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.
