The module detects movement within a 120° arc up to 5 metres away and automatically switches connected lighting on when motion is detected under low ambient light conditions. An override button on the face allows manual switching from AUTO mode to constant ON when extended lighting is needed.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential hallways, en-suites, utility rooms and commercial washrooms where hands-free lighting control reduces energy waste, the module operates on 230V mains and handles loads up to 100W LED or 200W incandescent. The fixed three-minute timer switches the light off after the last detected movement, while the fixed lux threshold ensures the sensor only activates in low-light conditions, preventing operation during daylight hours.\u003c\/p\u003e\n\u003cp\u003eThe module fits a 47mm minimum back box depth and slots into any compatible 50x50mm euro modular grid system. The black polycarbonate face sits flush with the surrounding faceplate once installed. The sensor lens is recessed into the face, reducing the risk of accidental contact or damage. Live and neutral wiring connects to screw terminals on the rear of the module, with clearly marked connections for load switching. The Class II construction requires no earth connection.\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.

This is useful when you need continuous lighting for an extended period without triggering the motion sensor repeatedly. The module returns to AUTO mode after the pre-set timer expires.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the timer or lux threshold be adjusted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The three-minute timer and lux threshold are factory-set and cannot be adjusted in the field. The sensor will only activate when ambient light falls below the fixed threshold, preventing operation during daylight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat faceplate is needed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe module requires a compatible euro modular grid faceplate that accepts 50x50mm modules. Knightsbridge produces grid plates in various finishes and gang configurations. The faceplate is sold separately and must be matched to the number of modules being installed in the same back box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it suitable for bathroom installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe IP20 rating means the module is only protected against solid objects larger than 12.5mm and has no water ingress protection. It can be used in bathrooms outside the designated zones (typically Zone 0, 1, and 2), but not within reach of a shower or bath enclosure.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293560922379,"sku":"NETPIRSBK","price":18.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/738064_894fa40a-15e0-467f-9434-9eddd6731efd.jpg?v=1714660430","url":"https:\/\/niori.co.uk\/products\/120-pir-sensor-module-with-override-50x50mm-black","provider":"Niori","version":"1.0","type":"link"}
