NP16161_01MS Schneider Unica KNX 2 Key Push Button Metallic Silver Backlit Scene Control Panel Unit

The NP16161_01MS is a two-key Unica KNX push button finished in metallic silver — a surface that reads as a machined metal face rather than painted plastic, making it the preferred choice where the wall device is part of the visible design. The functional description is straightforward: two keys, backlit symbols, an integrated bus coupling unit, and commissioning through ETS.

What makes this device more capable than a conventional switch is not the key count but the way the keys are configured. Each key can carry a short and a long operation, and the combination of the two can be used for scene recall and scene storage rather than simple switching. In idle state the face is uniform, with the symbols produced only by the backlighting. The brightness of that backlighting is set separately for day and night, so the panel remains legible when the room is lit and unobtrusive when it is not.

A metallic finish imposes two practical conditions that are easy to overlook. The first is that the fixing frame and cover frame must be ordered in a material that matches it, because the panel is supplied as the push button alone — and a mismatched frame is immediately visible on a metal face. The second is that the proximity function should be evaluated in the location where the panel will actually be fitted, since a sensor that wakes the symbols as a person walks past is useful in a circulation area but distracting at a desk.

On the programming side, the point to agree early is whether a key should recall a scene or toggle a group. The two behaviours are indistinguishable from the outside, and the difference only becomes apparent to the occupant when the lighting does not do what they expect. Recording the foil symbols along with the group addresses is what allows the panel to be understood by someone who did not commission it.

• Lobbies and reception areas — the clearest application, where a metal finish is chosen to match the joinery and the lighting is operated in a small number of named conditions.
• Executive offices and boardrooms — used where the room is set to a scene before a meeting and the panel is part of the interior.
• Hotel public areas and restaurants — applied where the lighting changes with the service period and the wall device is visible.
• Private residences — specified where the design of the installation is deliberate rather than incidental.
• Showrooms and retail interiors — used because the metal finish allows the same panel to be used across a large open area without becoming visually repetitive.
