The unit includes a built-in end-of-line resistor, removing the need for external EOL components and simplifying installation. A volume adjustment control on the device allows the output level to be set on-site to suit room size and ambient noise levels.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial fire alarm installations in offices, retail spaces, warehouses and residential communal areas, the MagDuo mounts directly to a wall using the included device base. The 2-wire connection means it draws power and receives trigger signals on the same pair of cables from the fire alarm panel, reducing wiring complexity compared to 4-wire sounders. The IP21C rating provides protection against solid objects larger than 12.5mm and vertically dripping water, making it suitable for internal dry locations.\u003c\/p\u003e\n\u003cp\u003eThe red ABS housing measures 150mm square with an 80mm projection from the wall once fitted. The grille apertures on the front face direct sound output forward into the space. The device base supplied with the unit clips onto standard UK back boxes and allows the sounder head to be removed for servicing or replacement without disconnecting the wiring.\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\u003e0.25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e150\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e80\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_MAGDUOSRSQ_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_MAGDUOSRSQ.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the built-in end-of-line function?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MagDuo includes an internal end-of-line resistor, which means installers do not need to fit an external EOL component at the last device on the circuit.
