Product Description
All-round motion detection from the ceiling
STEINEL MD IR N360 uDIM AP is a standalone nexx.IS PRO motion detector in anthracite RAL 7016, manufacturer article 080044. This is the surface-mounted 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.
Surface mounting and the gallery example
This AP article has an Ø80 × 93 mm housing and a net weight of 165 g. It attaches to the ceiling surface, and the current exact product specification identifies outdoor use. The shared manual permits installation heights of 1.8–6 m with an optimum position at 2.5 m. The sensor unit is rated IP54 with an ambient temperature range of −20 to +40 °C. Prepare cable entries and housing connections according to the instructions; a qualified installer connects the 220–240 V supply.
The first gallery image shows the offered anthracite RAL 7016 surface-mounted version. The manufacturer’s night entrance photograph is an MD IR N360 family application example from recessed DE material; it does not establish installation of this exact AP article, colour or uDIM interface. The luminaires, bicycles and other equipment shown are not included. Coverage and dimension drawings help assess placement, while load compatibility must be checked against the specific uDIM instructions before installation.
