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.

ATSUMI ACTIVE INFRA RED BEAMS

 

Features:

  • Dual beams : Offers stable operation without false and miss alarms.

  • Newly designed spherical Fresnel lens : Makes the very sharp beam ray and contributes to achieve the high performance features.

  • Easy optical alignment: 3 methods are adopted. For rough alignment : Scope, and for precise alignment : LED and Volt meter.

  • IP55 : Protect the inside of the detector from rain, snow, dust, sand and other objects which comes inside.

  • Unique knockout structure: Allows the surface wiring keeping IP55.

  • AGC (Auto gain control) : Control NRTS by following the various circumstance.

  • 100 times sensitivity: Stable operation is maintained even if 99% beam power is lost.

ATSUMI ACTIVE INFRA RED BEAMS - STACKABLE

NRQM series are higher grade models of NRQS series. The unit can be stacked up to four units.

This enables to create a 2-meter high infrared beam wall, which achieves high-density surveillance

 

Features:

  • Selectable frequency 4 channels: Stacking, Straight line, Square or other various applications are allowed.

  • Range: Outdoor 30m / 60m / 90m,

  • Indoor 60m / 120m / 180m

  • Dual beams : Offers stable operation without false and miss alarms.

  • Newly designed spherical Fresnel lens : Makes the very sharp beam ray and contributes to achieve the high performance features.

  • Easy optical alignment: 3 methods are adopted. For rough alignment : Scope, and for precise alignment : LED and Volt meter.

  • EDC (Environmental Discrimination circuit) : Beam reception level is severely dropped in heavy fog, snow and rain, often causes false alarms. EDC signal is output when the beam receiving power down.

  • IP55 : Protect the inside of the detector from rain, snow, dust, sand and other objects which comes inside.

  • Unique knockout structure: Allows the surface wiring keeping IP55.
