D2000-type ceiling emitters are ready-for-connection units available in two sizes: The standard D2036 version measures 905mm in length, whilst the compact D2018 version measures just 430mm. Both models have an instrument height of 100mm, and with a width of just 35mm are exceptionally slim. The units may be equipped with different tubes. They bear the CE mark, and are compliant with VDE and ENEC standards.

The units may optionally be equipped with an inversely switched movement alarm, which automatically switches off the unit in the event of spatial movement.
