Red Barrier series Photoelectric Beam DetectorsRed Barrier NR60QS / 110QS / 160QS

The synchronized quad beams together with unique Beam Power Control function eliminate false alarms and miss alarms.

  • Quad beams detection
    Four (4) synchronized pulsed infrared beams ensure ultimate stability in any applications.
    They eliminate false alarms by small animals, falling leaves, insects and other small objects .

  • Double modulated beams
    Double modulated beams eliminate influence of External Light and Electro Magnetic Interference

  • EDC (Environmental Discrimination Circuit)
    When the beam reception level is severely dropped in heavy fog, snow or rain, they often cause unwanted alarm activations.
    In case of such conditions, environmental trouble signal is output to distinguish from intrusion. EDC gives additional stability in harsh environment.

  • 100 times sensitivity allowance
    Stable operation is maintained even if 99% of beam energy is lost by fog, snow, frost, insect and etc.

  • Easy optical alignment
    Three alignment methods are available and they achieve easy and quick installation.
    Scope, Three LEDs, Volt meter

  • More features for stable operation.

Selection Tips

An alarm is activated when a receiver does not detect an infrared beam from a transmitter for a certain length of time. As the infrared beams are designed not to spread into a wide angle, and the two units (transmitter and receiver) can be installed with a long distance apart, the units are ideal for long-distance surveillance on a perimeter around plants, buildings and facilities, and also appropriate for surveillance in a specific narrow area. With the ability to minimize the influence of external light and electromagnetic interference, stable operation is ensured. As the unit is equipped with four (4) synchronized pulsed infrared beams, higher-precision surveillance can be achieved, compared to NRTD series with only two (2) beams.
