High Sensitivity Recessed DALI Passive Infrared Detector


The DDC317 high sensitivity presence or absence detector provides automatic control of lighting loads in buildings and interior spaces with high ceilings. The DDC317 is typically installed in warehouses, sports halls and atria and is used in other applications where the required mounting height exceeds that of standard detectors.

The detector uses a highly sensitive passive infrared sensor within a precision dome lens, which enables the DDC317 to reliably detect movement over large areas. Vertical mounting heights of up to 15m can be accommodated.

The detection area can be customised (in slot shaped or radial patterns) using a highly innovative clip-on masking shield. The two part mask is supplied as standard.

The DDC317 can be flush fitted in to ceilings that have sufficient void space or can be mounted directly to a solid ceiling or slab using the ASENS-CPIR-BOX.

As with other system sensors within the range, the DDC317 can be configured using system software and all the functions programmed remotely.
