Description

MEAN WELL DLS-208-P DALI-2 PIR Motion Sensor

MEAN WELL DLS-208-P is a DALI-2 PIR motion sensor with daylight measurement for indoor lighting. It is powered from the 9.5–22.5V DC DALI bus and supports ceiling flush or surface mounting, typically at 8 m. A surface-mount base is included as standard.

Sensing and electrical specifications

Parameter	Details
Model	DLS-208-P
Model code	DLS identifies the DALI sensor series; 2 denotes DALI-2; 08 identifies the high-mounting type with a typical 8 m mounting height; P denotes PIR sensing.
Device function	DALI-2 input device combining passive infrared (PIR) motion detection with a built-in daylight sensor. It supplies detection information to a compatible DALI-2 lighting controller.
Bus supply	9.5–22.5V DC, powered directly from the DALI bus.
Current consumption	Typical current < 10 mA at 16V DC; maximum inrush current < 20 mA.
Start-up	A 10 s self-test starts at first power-up. External motion detection is disabled during this period.
Protocol and DALI standards	DALI-2 certified; compliant with IEC 62386-101, -103, -303 and -304.
Hold time	5 s sensor hold time plus the hold time configured in the DALI master.
Daylight measurement	2–65000 lux.
Factory defaults	Delay setting: 5 s; indicator light: ON.
Detection radius	5–6 m at a mounting height of 10 m, at 25°C, 100% sensitivity and tangential motion. This radius is specified at 10 m, rather than the typical 8 m installation height.
Motion detection	Detects movement from people or pets. The human movement signal described in the catalog is significant movement such as walking; detection is not a guarantee of stationary presence.
Detection conditions	The specified radius is based on 100% sensitivity and tangential movement at 25°C. The Fresnel lens detects tangential movement farther away than radial movement. Detection range may increase as temperature falls and decrease as temperature rises.

Mounting and dimensions

Parameter	Details
Mounting method	Ceiling flush or surface mounting. The base required for surface mounting is included as standard.
Mounting height	2.5–10 m; typical and recommended installation height: 8 m.
Ingress protection	Flush mounting: IP20. Surface mounting: IP54. Both installation methods are for indoor use; do not install outdoors.
Ceiling opening	Ø55 mm for flush mounting.
Dimensions	Ceiling flush mounting: 105 × 105 × 80.8 mm. Ceiling surface mounting: 105 × 105 × 65.8 mm. Follow the mechanical drawing for the selected mounting arrangement.
Terminal layout	The four contacts in the connector drawing are labeled DALI+, DALI−, DALI+, DALI− from left to right.
Catalog packing reference per unit	0.25 kg (250 g), from the catalog PACKING entry; not a measured net weight.

Environment and standards

Parameter	Details
Operating environment	−25 to +50°C; 10–85% RH. Indoor installation only.
Storage environment	−40 to +80°C; relative humidity ≤ 85%.
Safety standards	EN 60669-1; EN IEC 60669-2-1.
EMC standards	Emission: EN IEC 55015. Immunity: EN IEC 61547.

System integration

Parameter	Details
System compatibility	Use a DALI-2 controller that supports these input devices, such as MEAN WELL DLC-02. The catalog shows a lighting system with a controller, DALI LED drivers and DTP touch panels for switching, dimming and scene control.
Bus current budget	Check the complete system’s bus current and controller input-device limit. The DLC-02 example permits up to 12 input devices per channel, subject to available bus power: 250 mA − (64 drivers × 2 mA) = 122 mA; at 10 mA per input device, up to 12 fit this example.
Manufacturer warranty reference	The manufacturer states a 5-year warranty under normal use. Follow the manufacturer’s terms and do not replace parts or modify the product to retain warranty eligibility.

Installation and commissioning

Parameter	Details
Qualified installation	Installation and wiring must be performed by a licensed electrician with power disconnected. Use indoors only.
Sensor positioning	Avoid reflective objects directly in front of the sensor and locations with frequent temperature or airflow changes. Keep at least 2 m from strong electromagnetic sources such as Wi-Fi routers, security cameras and microwave ovens. Motion sensitivity may fall or become unresponsive near 36–37°C.
DALI bus connection	Connect to the polarity-free DALI bus using 0.5–1.5 mm² conductors (AWG 20–16). An additional independent DALI bus power supply is unnecessary when the application controller already provides bus power.
Controller commissioning	Lighting actions are configured through a compatible DALI-2 application controller. The DLC-02 example scans and pairs real lamps and input devices with their configured virtual devices, then downloads device parameters and effects. Example brightness levels, groups and time delays are application settings.
Flush mounting	Assemble the base accessories with the sensor, then use a 55 mm opening in a ceiling no thicker than 20 mm. Connect the DALI wiring, fold the spring clips back, insert the assembly and check that it is securely seated.
Surface mounting	Open the prepared base screw holes and the required cable outlet. The manual shows two M6×28 mm plastic expansion tubes, two M3.5×26 mm self-tapping screws to secure the bottom cover, and four M3×8 mm screws to secure the wired sensor. Pass the DALI cable through the cover, connect it to the sensor and snap the face cover into place.
