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

|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.
