The 320 PIR Sensor is a compact sensor that provides energy saving functions in a DALI system. It can turn the lights on when its coverage area is occupied, and off when it is unoccupied. 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.

The 321D2 Multisensor is a DALI-2 certified version of the 321 Multisensor, which combines a light sensor for constant light control and a passive infrared (PIR) presence detector to provide energy-saving functions in a DALI system. The light sensor measures reflected light from the surface directly beneath it, using this information to maintain a constant light level by adjusting the lamp outputs. The PIR sensor enables the Multisensor to switch the lights on when its coverage area is occupied, and off when it is unoccupied.
