Bộ cảm biến Helvar - 322 High Bay Multisensor

322 High Bay Multisensor


 322, 322B




 Automatically control lighting loads at heights that are too high for general sensors



 The High Bay Multisensor is a compact unit that provides energy-saving functions in DALI applications where mounting heights are too high for standard sensors, such as warehouses and factories.

Sealed with a gasket that protects it from dust and water, this IP65 sensor is designed to be recessed in a ceiling void or in a luminaire construction.

Since its detection sensitivity is less dependent on movement direction than that of most PIR sensors, fewer units are required to reliably cover a target area.

The unit features:

  • A passive infrared detector (PIR), which detects movement within its coverage area, allowing load control in response to changes in space occupancy. It switches the lights on when its coverage area is occupied, and off when it is unoccupied
  • A light sensor, which provides a bright-out function: it can be programmed in Designer to switch off the lights when the natural light rises above a predefined illuminance threshold.


The High Bay Multisensor is compatible with Helvar’s lighting systems and configuration software, Designer and Toolbox




 Key Features

  • Excellent detection performance through high sensitivity and multidirectional coverage
  • Suitable for applications with very high ceilings
  • Protected against dust and water (IP65)
  • Programmable bright-out control for energy efficiency (on;y available on a lighting router system)
  • Simple connection and integration into a Helvar DALI control network.
  • Programmable in Designer and Toolbox
