INDEXA detector de movimiento empotrable 33551 para Gira System 3000, 180° PIR, 2300W

Install the INDEXA 33551 motion detector in a Gira System 3000 flush-mounted box to automate lighting in hallways, stairwells, or utility rooms. It detects movement across a 180° field and switches connected loads up to 2300 W for incandescent or halogen lamps, or up to 400 W for LED lighting. The integrated acoustic sensor can be enabled for presence detection, and the teach-in function lets you set the brightness threshold for automatic activation.

Why choose it

This detector combines reliable PIR motion sensing with an optional acoustic sensor for presence detection, making it suitable for areas where movement may be limited. The teach-in function allows you to set the exact brightness level at which the light should switch on, reducing unnecessary operation.

Ideal use cases

• Hallways and corridors in residential or commercial buildings
• Stairwells requiring automatic lighting control
• Utility rooms, basements, and garages
• Integration into Gira System 3000 installations

Good to know

The detector is designed for flush mounting in a standard System 3000 insert. It operates on 230 V AC and supports manual override via an extension input. The acoustic sensor can be switched off if not needed.
