The card slots directly into the master station housing and connects via screw terminals marked for Line 0+ and Line 0-, with duplicate terminals for each of the two lines it adds.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and commercial intercom installations where additional door stations, sub-stations, or remote call points need to be added after the initial master station installation, the BM2EX is compatible with both the BM2 2-line master station and the BM4 4-line master station. Each expansion card occupies one of the available expansion slots inside the master station enclosure, so a BM2 can accept up to three BM2EX cards (reaching 8 lines total), while a BM4 can accept up to two BM2EX cards (also reaching 8 lines total).\u003c\/p\u003e\n\u003cp\u003eThe card measures 130mm x 110mm x 35mm and weighs 20g, fitting within the master station's internal depth without requiring enclosure modification. The green screw terminal blocks accept standard twisted-pair wiring used throughout the Beacon EVCS range, and the red PCB substrate includes clear terminal labelling to reduce installation errors. Once installed, the expansion lines operate identically to the master station's native lines, with no performance difference between base and expanded capacity.\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\u003e0.02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.05\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.05\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e130\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e110\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e35\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e130\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e110\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e35\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_BM2EX_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_BM2EX_Instructions.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhich master stations is the BM2EX compatible with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe BM2EX expansion card is compatible with both the ESP Beacon BM2 2-line master station and the BM4 4-line master station.
