DALI (GII): Corridor Function & Parametrization Possibilities
a) Description
The Corridor Function is a Driver`s Automatic Dimming Functionality of ALL OSRAM DALI (GII) ECGs having the Corridor Function
Symbol on their Rate Stamp. Switching the mains voltage (220-240V, 50/60Hz) on the DALI Inputs (DA, DA) of the ballasts via
commercial Relay Presence detectors (or Staircase Automates) triggers the Automatic Corridor Dimming behaviour. This solution is
used for cost-effective Energy Saving installations in Floors, Staircases, Storage Halls etc. w/o add. Light Management Peripheries.
OSRAM DALI (GII) drivers being in Corridor Mode are synchronized via the mains frequency (50/60 Hz) to guarantee SAME operation
behaviour when controlled by the SAME sensor – the number of participants in one Corridor Mode control loop is only limited by the Sum
of participants` Inrush Currents allowed per Phase.

b) Entering/Leaving the Corridor Mode
The Corridor Mode can be entered (from DALI or TouchDIM Mode) by providing a 220-240V/50,60Hz Signal on driver`s DALI input for
longer than 120 (50 Hz), 100 (60 Hz) seconds, permanent. Defined change-over from Corridor Mode to TouchDIM Mode by 5 single
short push events (Push Button, switching mains 220-240V/50,60Hz) w/in 3 seconds.
c) Parametrization of Corridor Function
The 3-Levels Corridor Function can be easy set via DALI magic/wizard System (see also DALI wizard manual). The settings (Light
Levels (A, B, C), Delay- & Stand-By Times (D0, T1, T2), Fade Down Times (F1, F2)) are stored in the ballast - no intelligent external
peripheries are needed.
