Staircase controllers enablesequential switching on of staircase lighting. They switch on light points sequentially with a set delay for a specified period of time. This creates a wave of lighteffect on the stairs. We offer the AS-225 staircase controller for flush mounting or the 12-channel AS-225D controller for rail mounting. They allow you to control the light manually using buttons or automatically using motion sensors, such as the DRL-12 laser sensor.
