Product Definition
A stair sensor switch (model RL-STEP-03-08) is a lighting control device designed to automatically turn LED stair lights on when motion is detected and turn them off after motion ceases. It supports DC12-24V LED systems and provides an energy-efficient solution for stair and hallway lighting control.
Key Features
• Automatic motion-activated on/off control for LED stair lighting
• Works with DC12-24V LED systems
• Improves safety and convenience in stair areas
• Reduces unnecessary energy consumption
• Compact design for easy installation
Typical Applications
• Staircase LED lighting control
• Hallway or corridor lighting automation
• Entryway and landing lighting systems
• Indoor architectural LED illumination
Sensor Working Principle
The built-in motion sensor detects human presence and triggers the lighting to turn on. After no motion is detected for a set period, the switch automatically turns the lights off, conserving energy and enhancing safety.
Installation & Usage Notes
• Ensure proper DC12-24V LED power supply connection
• Install the sensor in a position with clear motion detection range
• Avoid installing in areas with frequent non-target movements (e.g., HVAC vents)
Summary
This RL-STEP-03-08 stair sensor switch is an ideal solution for automatic LED stair lighting control, providing convenience, safety, and power-saving performance in residential and commercial indoor stair applications.
