DDC312

Compact Recessed DALI Multi Detector

DDC312

The DDC312 multisensor is a compact unit containing sensors to provide energy saving functions when used in a DALI system. It contains a photocell, a passive infrared occupancy detector and an infrared receiver to receive commands via infrared remote control.

The light sensor measures the room's ambient light level. The PIR detector enables the system to detect when an area is occupied.

Features

  • Presence detection has a default timeout of 20 minutes
  • Programmable constant light control for energy efficiency
  • Complete control using the hand held infrared remote control DDC303
  • A local switch can be connected to provide on / off and a manual dimming function
  • The DDC312 programmable functions can be set using 5 DIL switches at the back of the unit
  • These DIL switches can be overridden remotely using system software
  • The coverage restrictor can be fitted to the light sensor for more precise control

Additional Functions

A remote control handset can program most functions, software will give full system control. When multiple linked presence detectors are connected in one system, they will communicate with each other and switch off loads when all sensors do not detect occupancy. The automatic on / off sequence of the presence detection system has three programmable steps (on, intermediate, off).
