The black polycarbonate faceplate houses a PIR sensor with a 120° field of view and a detection range of up to 5 metres, automatically triggering connected lighting when movement is detected within range.\u003c\/p\u003e\n\u003cp\u003eDesigned for hallways, corridors, bathrooms, utility rooms and commercial restrooms, the module replaces a standard grid switch position and operates on 230V 50Hz mains wiring via live and neutral connections. The sensor includes a built-in time delay of 3 minutes (lights remain on for 3 minutes after the last detected movement) and a lux threshold that prevents activation when ambient light exceeds a preset level, so the lights only trigger in low-light conditions.\u003c\/p\u003e\n\u003cp\u003eThe module accepts a maximum load of 100W LED or 200W incandescent lighting, suitable for most domestic and light commercial installations. The 40mm recessed depth requires a minimum 47mm back box for safe installation, and the module clips into a compatible euro grid frame (sold separately). The black finish pairs with Knightsbridge's grid faceplate range in black, chrome, brass and steel finishes. Class II construction means no earth connection is required.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecessed Depth\u003c\/td\u003e\n\u003ctd\u003e40 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin.
