## Long description

Ceiling motion presence detector Legrand 999835 IP20 84×36 mm is a ceiling-mounted sensor for indoor use that detects both motion and presence to control lighting and automation systems.

 Protection class: IP20 — suitable for indoor, dry environments
 Dimensions: 84 × 36 mm (diameter/height format for ceiling fitting)

 Integration: designed for connection to lighting and automation control circuits
 Typical applications: occupancy sensing for automatic switching and energy saving
How to use
Install the detector into a compatible ceiling cut-out following mounting instructions and electrical safety standards. Connect the sensor to the lighting circuit or building automation wiring according to wiring diagrams provided by the system integrator or product manual. Adjust detection sensitivity and time-delay settings if available to match room size and use patterns. Test the device after installation to confirm reliable detection coverage and switching behaviour before regular operation.
Usage recommendations
Mount the detector centrally in the room or along the main circulation path for optimal coverage; avoid pointing the sensor directly at large windows or air-conditioning outlets that may cause false triggers. Use sensitivity and time-delay adjustments to minimize unwanted switching while ensuring prompt response when spaces become occupied. For humid or outdoor locations select a product with a higher protection rating.
