Product Description
All-round motion detection from the ceiling
STEINEL MD IR N360 uDIM DE is a standalone nexx.IS PRO motion detector in anthracite RAL 7016, manufacturer article 087456. This is the recessed ceiling version with 360° passive infrared detection, intended to control separately selected entrance, passage or approach lighting. It detects changes in heat radiation from moving people and takes the surrounding light level into account. The ceiling format suits places requiring an all-round field below the mounting point, while its settings allow the lighting response to follow the way that people use the approach.
The manufacturer specifies a tangential zone of up to Ø26 m. In the shared manual, this diameter is illustrated at a mounting height of 2.5 m, with a conventional radial detection radius of 3 m. The current specification separately lists a nominal radial zone of Ø7 m. Head-on movement and movement across the field produce different detection results, so the zones should be assessed for the actual walking direction and installation height. Walls, glazing and other obstacles interrupt the detector’s infrared view.
Eagle Eye and four adjustable sensing sectors
The Eagle Eye window in the lens improves approach detection in a selected direction. At 2.5 m height, the manual gives this area a reach of up to 6 m from the detector. Align the window with the entrance or path, then use the supplied cover clips to mask unwanted segments. This is useful where a public footpath or another frequently used area sits beside the intended approach and should not determine the response of the connected lighting.
MD IR N360 has four PIR sensors with individually adjustable sensitivity between 1 and 100 percent. Configure the settings in the app and check movement along the intended route and at the edges of the field. Test mode works independently of ambient brightness and also allows the response to be assessed through the status indicator without a connected load. Install the unit on a stable base so that movement or vibration of the housing does not cause unwanted triggering.
App settings, twilight and lighting groups
STEINEL Connect and Bluetooth Mesh provide configuration from a compatible smartphone or tablet and wireless organisation into lighting groups. Group members follow shared control parameters while individual sensitivity can still be set for each sensor. The neighbouring-light function coordinates connected approaches. The detector can also operate on its own. When another mobile device needs configuration access, the network key is shared through the app, allowing the existing lighting network to be managed from that device.
The stay-on time after movement can be chosen from 5 seconds to 60 minutes, with a twilight threshold between 2 and 2000 lux. Teach-IN saves the brightness measured on site, making it practical to choose the desired switching condition at dusk. Daytime mode allows movement-based operation or testing independently of natural light. These settings help the response suit the actual entrance, while the test mode makes it easier to check the final placement and masking.
Phase dimming for compatible light sources
uDIM is a universal phase-cut dimming output that automatically selects leading-edge or trailing-edge operation. Connected light sources must be dimmable and compatible with this control method. Main-light and basic-light brightness can be set between 5 and 100 percent; basic light can be linked to time or ambient brightness. The fade time for switching on and off is adjustable from one to three seconds. These functions allow a gentler lighting transition at the entrance with suitable conventional luminaires.
The manual specifies 5–100 W for LED loads at cosφ 0.9, and 20–250 W for incandescent or halogen lamps. Electronic transformers are rated for 5–100 W at cosφ 0.9, while inductive transformers are rated for 5–100 VA. These four load categories must not be mixed on the same output. Check control compatibility before selecting the luminaires: the manual explains that new or untested loads may exist which do not operate with the uDIM version.
Recessed installation and connection-box placement
This DE version has an Ø83 × 74 mm sensor head and a net weight of 165 g. The head fits into a Ø68 mm ceiling cut-out and is retained by springs. Allow room above the ceiling for the separate 109 × 63 × 30 mm connection box and its cable. The linked manual permits indoor and outdoor installation at heights of 1.8–6 m, with 2.5 m identified as optimum. IP54 applies to the sensor head, while the connection box is IP20. For an outdoor installation, the connection box therefore needs a suitably protected position away from moisture. The operating temperature is −20 to +40 °C; the supply is 220–240 V AC, 50–60 Hz.
Before specifying this recessed format, assess the available ceiling void, cable entry and future access to the connection box. Keep the infrared lens clear of trim or luminaire housings. The connected LED load must meet both the minimum and maximum rating. A five-percent setting does not mean every compatible driver produces the same light level. Check the transition and stable operation at the chosen brightness levels after commissioning. The detector has no constant-light regulation; its app configures movement and twilight conditions, selected brightness levels and group behaviour.
Images and the offered version
The first gallery image shows the offered anthracite RAL 7016 MD IR N360 uDIM DE article 087456. The manufacturer’s night entrance photograph is an MD IR N360 DE family application example; it does not verify installation of this exact article, colour or uDIM interface. The luminaires, bicycles and room equipment are not included. The coverage illustration is the current family drawing at 6 m mounting height. The dimension drawing and uDIM circuit diagram come from the manufacturer’s exact article documents.
