The unit converts 230V mains to regulated 24V DC output, housed in a white ABS plastic box with a wall-mount plate and a compact form factor measuring 105mm x 105mm x 110mm.\u003c\/p\u003e\n\u003cp\u003eDesigned for commercial fire alarm installations where electromagnetic door holders need a dedicated power supply independent from the main fire panel, the MAGfire pairs with 24V DC mag-lock door holders rated up to 48W total load. The boxed housing protects the transformer and circuitry from dust and accidental contact during maintenance, while the wall-mount plate allows surface fixing to walls or inside plant cupboards close to the door location.\u003c\/p\u003e\n\u003cp\u003eThe 2A output capacity handles a single high-holding-force door holder or multiple lower-rated units wired in parallel. The white ABS casing blends into typical building service areas and the compact 105mm-square footprint means it can be tucked into ceiling voids, cupboards or behind door frames where mains power is available. The unit includes a screw cap for cable entry and exit.\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\u003e0.42\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.48\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.48\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e105\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e105\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e110\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_DR916-24_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_DR916-24.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is this power supply used for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe MAGfire DR916-24 powers 24V DC electromagnetic door holders in fire alarm systems.
