Description Electronic Dimmer, 15.10 Control of up to 32 slave dimmers or direct control of a 0-10 V load (e.g., electronic ballast). Selectable memory. Staircase lighting function with pre-warning before shutdown. Dimming speed is adjustable. Output contact 6 A for switching the load. Connection voltage 110-230 V AC. The Master Dimmer type 15.10 from FINDER provides a warning before it switches off. Equipped with a pre-warning function, it is possible for the staircase or corridor light to initially dim to 50% after a set time, before completely shutting off after an additional 10 seconds within 30 seconds. This pre-warning function according to DIN 18015-2 significantly reduces the risk of accidents, especially in staircases, as people are no longer suddenly in the dark. FINDER has combined all the functions needed in modern building automation into a compact device with the Master Dimmer 15.10. This includes dimming all common light sources with and without memory functions.
