Product Description
STEINEL IR Quattro MICRO 6m is a compact presence detector for projects that call for an unobtrusive installation in the ceiling. Once installed, only a small white trim and the 15 × 15 mm precision lens remain visible, while the main sensor body sits above the ceiling surface. It suits a single office, hotel room, care room, washroom or another compact indoor space. The white plastic housing has a RAL 9003 finish that integrates neatly with light ceiling surfaces. Its IP65 rating also permits use in indoor rooms exposed to moisture, subject to correct installation and the electrical requirements. This is a recessed ceiling device that provides sensing information or control commands within an appropriate building management system.
MICRO detects tangential movement over 6 × 6 m and presence over 4 × 4 m at the manufacturer's illustrated mounting height of 2.8 m. The permitted installation height is 2–5 m, and the light measurement range is 2–1000 lx. Spring clips secure the sensor in an opening up to 35 mm; the instructions require at least 120 mm of clear installation depth. The DALI bus supply range is 12–22.5 V DC.
Passive infrared technology (PIR) responds to moving sources of heat. For presence monitoring, it also detects smaller movements made by a person working at a desk. The detection angle is 360°, with a square pattern across the floor. Coverage should be planned around the installation height and actual workstation positions, because tall furniture, partitions and other obstructions can block the sensor's view. A PIR detector cannot guarantee recognition of a completely motionless person regardless of conditions. The manufacturer illustrates the detection area at a mounting height of 2.8 m; commissioning should include checking the places where occupants will sit and work. Measurement of ambient brightness complements the motion information, allowing the lighting system to take available daylight into account.
This version is a DALI-2 Input Device (IPD). The sensor takes power and communicates through the DALI bus, sending motion and brightness information to an external DALI application controller. Depending on the system configuration, the controller can request measured values or receive event-driven and periodic reports. The manufacturer's instructions refer to IEC 62386 parts 101, 103, 303 and 304. A compatible controller, bus power supply and appropriate lighting control gear are required to turn this information into switching or dimming behaviour. The detector is not an autonomous DALI APC application controller and does not provide a relay for directly switching a 230 V luminaire. Constant-light operation is implemented by the system controller using the sensor's measured brightness. Required delays, lighting targets and operating scenes are configured as part of the control system design, so the purchase should take account of every necessary system component rather than the appearance of the sensor alone.
Choose a position with a clear view of the monitored area and suitable separation from sources of heat that could affect detection. Heating equipment, air movement and moving objects within the planned zone deserve attention during commissioning. Space must be available above the ceiling for both the sensor housing and its connection; a small visible trim does not imply an equally small installation depth. The installation box, bus power supply, actuators and control unit should be selected to suit the actual project. If necessary, the sensor lens can be wiped with a damp cloth without cleaning agents. STEINEL states a five-year manufacturer's warranty for this Professional Line device, subject to the applicable warranty conditions.
