This motionactivated staircase lighting controller provides automatic, adjustable illumination for indoor stairways and handrails. It combines stepbystep motion sensing with flexible brightness control and lowvoltage operation to improve visibility and convenience where people move between floors. Key benefits Increases safety and convenience: Motion sensing turns lights on as someone approaches and off after they leave, reducing trips and fumbling on dark stairs. lighting: Five brightness levels (10% to 100%) let you match illumination to the location and user preference, from subtle guide lighting to full brightness. Energy efficient and automatic: Fully automatic operation only powers lights when motion is detected, saving energy compared to leaving lights on continuously. Compatible and easy to integrate: Designed for lowvoltage DC12V and DC24V LED lighting systems commonly used in stair and handrail installations. Built for stable performance: Lowvoltage input plus short circuit guard and antileakage protection help maintain reliable operation in residential and commercial settings. Features Motion sensing: Advanced sensor detects movement and activates lights stepbystep for consistent staircase coverage. Brightness control: Fivestep adjustment from 10% to 100% to suit different tasks and ambient lighting conditions. Automatic controller: Hands operation that switches lights on when motion is detected and off after movement stops. Electrical compatibility: Works with DC12V/24V LED drivers and fixtures. Protective measures: Short circuit guard and antileakage protection are included to reduce the risk of electrical issues during use. Typical applications Indoor residential staircases and hallways for safer nighttime passage. Commercial stairwells and handrails in office buildings, hotels, and multiunit housing. Entryways, corridors, and intermediate landings where motiontriggered guide lighting improves accessibility. This controller is intended for use with compatible lowvoltage LED lighting systems in indoor environments. It provides automatic, adjustable illumination with protective features to support reliable daily operation.
