Description
Long Range Photobeam Detectors are easy-to-install with laser beam alignment and provide extended range. Designed to provide reliable perimeter security both indoors and outdoors. With the new E-964-D390Q, four selectable beam frequencies reduce interference between multiple units for enhanced perimeter protection.
- Built-in laser beam alignment system speeds accurate, reliable positioning
- Twin infrared beams provide reliable perimeter security, minimizing false alarms from falling leaves, birds, etc.
- Lensed optics reinforce beam strength & provide excellent immunity to false alarms due to rain, snow, mist, etc.
- Weatherproof (IP55), sunlight-filtering case for indoor & outdoor use
- Anti-frost system so that beam functions even in extreme conditions
- Automatic input power filtering with special noise rejection circuitry
- NC/NO alarm output
- N.C. tamper circuit included
- Non-polarized power inputs
- Quick, easy installation with built-in laser beam alignment system
- Interruption time adjustable for nearly all situations

Troubleshooting
| Situation | Possible Issue | Solution |
| Transmitter LED does not light. | Incorrectly wired and/or insufficient voltage. | Ensure the power supply to the transmitter is 12 to 24 VAC/VDC. |
| Receiver LED never lights up when the beam is interrupted. | a. Insufficient voltage. b. Beam reflected away from receiver. c. Beams not simultaneously interrupted. |
a. Double-check the voltage. b. Clean the cover. c. Check overall installation. |
| Beams interrupted and LED lights, but no alarm trigger. | Alarm trigger cable may be cut, or the relay contact stuck due to overloading. | Check the continuity of the wiring between the sensor and the alarm |
| Alarm LED continuously lit. | a. Lenses out of alignment. b. Beams are blocked. c. Cover is foggy or dirty. |
a. Realign the lenses. b. Remove any obstacles. c. Clean the cover. |
| Alarm trigger becomes erratic in bad weather. |
Lenses out of alignment. | Check overall system installation. If still erratic, realign the lenses. |
| Frequent false triggers from leaves, birds, etc. |
a. Too sensitive. b. Bad location. |
a. Reduce the response time. b. Change the transmitter and/or location. |
