A 12/24 volt stair controller is a device designed to control the lighting of a staircase. It is typically used in residential or commercial buildings to provide safe and energy-efficient lighting for staircases.

The controller operates on either 12 or 24 volts, depending on the voltage of the lighting system it is connected to. It is typically installed at the bottom or top of the staircase and is connected to a sensor that detects movement on the stairs.

When motion is detected on the stairs, the controller activates the lights, illuminating the stairs for safe passage. The controller can be programmed to control the brightness, color, and duration of the lighting, allowing for customizable and energy-efficient lighting solutions.

The 12/24 volt stair controller can also include additional features such as timers, motion sensitivity adjustment, and manual override. The manual override feature allows users to turn on or off the lights manually, providing added flexibility and convenience.

Overall, the 12/24 volt stair controller is a simple and effective solution for providing safe and energy-efficient lighting for staircases. It can be used in a variety of residential and commercial settings to improve safety and enhance the aesthetic appeal of the space.
