The unit features a three-digit LCD display showing test duration in minutes, a rotary key selector for choosing between four pre-programmed test intervals (10, 30, 60 and 180 minutes), and an optional audio buzzer that sounds when the test period completes.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial, industrial and public buildings where emergency lighting systems require regular functional testing, the switch mounts on a standard single-gang UK back box and controls lighting loads up to 4A LED, 10A incandescent or 6A fluorescent. The key-activated operation prevents accidental or unauthorised testing, making it suitable for schools, offices, retail premises and hospitality venues where building management staff need to conduct monthly and annual duration tests without interference.\u003c\/p\u003e\n\u003cp\u003eThe compact 93mm x 90mm faceplate is manufactured from antimicrobial urea, a thermosetting polymer that inhibits bacterial growth on high-touch surfaces. The white finish integrates cleanly into standard electrical accessory layouts. Operating voltage is 220-240V AC, compatible with UK mains supply. The LCD display remains visible in low light, allowing test operators to monitor progress without needing additional illumination.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.19\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e93\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e58\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e290\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e290\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e340\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_EMTSLCD_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_EMTSLCD-EMTS.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat test intervals does the switch support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFour pre-programmed intervals are available: 10 minutes, 30 minutes, 60 minutes and 180 minutes.
