Long-Distance Perimeter Security

Secure the perimeter around your home or property with Seco-Larm Enforcer Quad Photobeam Detectors. Quad photobeam detectors feature extended ranges that are ideal for long-distance protection. When the infrared light beams are broken, the sensors are activated and alert you to the intruder, helping you keep your home safe and secure.

  • Four selectable beam frequencies eliminate interference
  • Beam strength LED indicators
  • Audible beam alignment (buzzer)
  • Built-in heater for indoor or outdoor use
  • NO/NC alarm output

Available Variations:

  • 165Q: Up to 165 Ft. (50m) outdoors, 330 Ft. (100m) indoors
  • 330Q: Up to 330 Ft. (100m) outdoors, 660 Ft. (200m) indoors
  • 495Q: Up to 495 Ft. (150m) outdoors, 990 Ft. (300m) indoors
  • 660Q: Up to 660 Ft. (200m) outdoors, 1,320 Ft. (400m) indoors

Reduces False Alarms

Because all four beams must be simultaneously broken for activation, false alarms created by animals and falling leaves are minimized.

Built for Extreme Conditions

A built-in heater automatically turns on and off depending on the outside temperature. An environmental control output senses a slow degradation in beam strength when weather conditions worsen preventing false alarms. Lensed optics reinforce beam strength and provide excellent immunity to false alarms due to rain, snow, mist etc.

Easy to Align and Install

The built-in laser and visual alignment systems quickly and easily pinpoint the approximate mounting location for the transmitter and aid in aligning the transmitter and receiver units once mounted. A beam strength indicator clearly displays the strength of the beam at the receiver with 5 LEDs. Four selectable beam frequencies allow for superior perimeter protection by eliminating crosstalk and interference between multiple units.
