Ceiling Infrared Motion Sensor Switch Key benefits Automatic lighting when needed: Detects human movement and switches lights on when someone enters the detection area, then turns lights off automatically after a preprogrammed delay to reduce unnecessary energy use. Flexible operation: Adjustable lighting function allows the sensor to operate under both daylight and night lighting or to operate only at night, giving control that matches different installation needs. Simple installation: The detachable sensor head wire lets the sensor head pass easily through a ceiling hole for quick and neat mounting. Follow the included instructions for a straightforward setup. Wide coverage and reliable response: A 6 meter detection range and a 360 degree detection angle cover typical room layouts and reduce missed activations. Main features and specifications Function: Passive infrared motion detection that controls lighting based on human movement. Lighting modes: Operates under daylight and night lights, or night only. Detection range: Up to 6 meters. Detection angle: 360 degrees for fullarea coverage when ceiling mounted. Time control: Lights turn off after a preprogrammed delay once movement stops. Installation design: Detachable sensor head wire for easy routing through ceiling openings and compact ceiling mounting. Intended use areas: Designed to control ceilingmounted lighting circuits in spaces where automatic switching and energy saving are desired. Performance and compatibility Designed to work with standard ceiling lighting installations and circuits. It controls lighting based on infrared detection and does not require user intervention once set. Compact sensor head and detachable wiring make it adaptable to common ceiling hole sizes and retrofit applications. Provides consistent on off control to reduce energy waste in areas with intermittent occupancy. Suggested applications Hallways and stairwells: Automatically light transitional spaces only when they are in use, improving convenience and reducing wasted energy. Toilets and bathrooms: Suitable for bathroom installations in zone 3 only, where automatic lighting adds convenience and prevents lights being left on. Storage rooms and closets: Ideal for small utility spaces where lights are often left on by accident or where hands operation is preferred. Installation and use tips Pass the detachable sensor head through the ceiling hole before final wiring to simplify fitting. Choose the daylight plus night mode for areas where lighting should respond at all times, or night only mode where activation is required only in low light conditions. Consult the included instructions for wiring and mounting details and to confirm the preprogrammed off delay meets the needs of your space. This ceiling infrared motion detector provides a practical, easy to install solution to automate lighting, reduce wasted energy, and improve convenience in a variety of indoor locations.
