DDC441

DALI Presence Detector Interface

DDC441

The DDC441 Occupancy Detector Interface allows connection of other occupancy detectors to a DALI system. The input accepts a volt free normally closed contact. The pre-wired encapsulated circuit board is intended for mounting inside the wiring space of the detector.

The DDC441 includes a 12V DC supply (15mA max) to power the host detector.

All the parameters are programmable from within system software.

Key Features

  • Fits into the wiring space behind the sensor
  • Input for normally closed volt free switches compatible with security sensors
  • Fully programmable using system software
