360 Degree Mini Recessed PIR Ceiling Occupancy Motion Sensor Detector Light Switch A compact recessed PIR motion sensor that turns lights on only when a space is occupied. Adjustable sensitivity and timing give control over when and how long lights stay on, while a detachable sensor head and compact design make installation through a ceiling or wall opening simple. Key benefits Convenient automatic control: Detects occupancy and switches lights on and off without manual operation, reducing unnecessary lighting use. Flexible operation: Choose day and night operation or nightonly mode to match lighting preferences and avoid unwanted triggering during daylight. Wide and reliable coverage: 360 degree detection for ceiling mounting and 100 degree detection for horizontal mounting, with an effective range up to 6 meters. Easy to install and service: Detachable sensor head wire allows the sensor head to be passed through a hole for recessed mounting, then reconnected to the main box. run time: Set light ontime from 5 seconds up to 8 minutes to suit different spaces and traffic patterns. Features and performance Sensor type: Passive infrared occupancy detector for motionactivated switching. Detection angles: 360 degrees when mounted in the ceiling; 100 degrees for horizontal or wall installation. Detection distance: Up to 6 meters, providing broad coverage for small to medium rooms and corridors. Sensitivity modes: Selectable operation for day and night or nightonly detection. Time delay settings: Adjustable from 5 seconds to 8 minutes to control how long lights remain on after motion stops. Design: Mini recessed form factor with a detachable sensor head wire for straightforward throughhole installation. Compatibility and application Designed for recessed mounting in ceilings and for horizontal installation where a 100 degree detection angle is suitable. Intended to function as an occupancy motion switch for lighting circuits and similar applications that require automatic onoff control. Practical use scenarios Hallways and corridors: Install in a ceiling to provide full 360 degree coverage so lights activate as people move through with no need to search for switches. Stairwells and landings: Configure nightonly mode to provide illumination after dark while avoiding daytime activation. Storage rooms, closets, and utility areas: Use short time delays for brief visits or longer delays for tasks that require more working time, preventing lights from turning off prematurely. Installation tips The sensor head wire detaches from the main box, making it easier to feed the head through a cutout for recessed installation. Its mini design fits discreetly into ceilings or horizontal mounting positions where an unobtrusive presence is required. Adjust sensitivity and time delay after installation to optimize detection for the specific space and traffic patterns. This sensor provides a practical, adjustable solution for automatic lighting control in residential and commercial interior spaces where compact recessed mounting and flexible settings are required.
