Bộ cảm biến Helvar - 320D2 PIR Sensor (DALI-2)

320D2 PIR Sensor (DALI-2)


 PIR Sensor (320D2, 320BD2, 320PD2 and 320PBD2) Datasheet

 The PIR Sensor is a compact presence detector and DALI-2 certified input device. It can turn the lights on when its coverage area is occupied, and off when it is unoccupied. The sensor’s settings are adjusted using Helvar’s Designer Software

Due to its excellent detection performance, the PIR Sensor is especially suitable for applications where small or slow movements take place for extended periods of time, such as offices or classrooms. 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 can be mounted into a ceiling void or onto a solid surface using Helvar’s SBB-C (white) or SBB-CB (black) mounting box (sold separately).



 Key Features

  • Excellent detection performance through high sensitivity and multidirectional coverage.
  • 10 mA DALI current consumption.
  • Compact and functional design.
  • Programmable in Designer.
  • DALI-2 certified input device.
