PRINCIPLE:

The 3 Beam Active Infrared Photoelectric Detector is a long-range perimeter security sensor designed to protect open areas, boundary walls, gates, driveways, industrial premises, warehouses and other restricted zones. It uses three active infrared beams between a transmitter and receiver to create an invisible detection barrier. When all three beams are simultaneously interrupted, the receiver activates the alarm output. This simultaneous-beam detection helps provide reliable perimeter intrusion detection.

  • 3-Beam Active Infrared Technology – Uses three infrared beams to create an invisible security barrier.
  • Long-Range Perimeter Protection – Outdoor detection range available up to 250m, depending on model.
  • Indoor Range up to 750m – The corresponding indoor range is up to 750m for the 250m model.
  • Simultaneous 3-Beam Detection – Designed to trigger when the three infrared beams are interrupted together.
  • Adjustable Response Time – Response/interruption time can be adjusted from approximately 50–700 ms, allowing the system to be configured according to the protected area's requirements.
  • Beam Alignment Adjustment – Horizontal adjustment of approximately ±90° and vertical adjustment of approximately ±10° helps simplify transmitter-receiver alignment.
  • LED Signal-Level Indicators – Multiple level indicators help installers check and fine-tune beam alignment.
  • Alarm Relay Output – Provides NO/NC relay contacts for connection to compatible alarm panels and security systems.
  • Tamper Protection – Tamper output can indicate unauthorized opening/removal of the detector cover.
  • Wall or Pole Mounting – Suitable for installation on walls or poles.
  • Outdoor-Oriented Construction – The technical documentation specifies operation across approximately -25°C to +55°C with humidity up to 95%, depending on the exact version.

How It Works

In simple terms: Transmitter → 3 Invisible IR Beams → Receiver → Alarm Output

This makes it particularly useful for creating an invisible perimeter protection line across boundary walls, entrances, passages and open areas.

System Components

Transmitter: Sends the three modulated infrared beams toward the receiver.

Receiver: Receives the three infrared beams and provides the alarm relay output when the protected beams are interrupted.

Mounting Brackets: Allow the units to be installed on walls or poles and adjusted for proper alignment.

Protective Housing: Helps protect the internal optical and electronic components during outdoor installation.
