Description

The MAGfire DR916-24 is a 24V DC 2A boxed power supply designed for fire alarm electromagnetic door holders and automatic door release systems. 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.

Designed 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.

The 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.

Frequently Asked

What is this power supply used for?

The MAGfire DR916-24 powers 24V DC electromagnetic door holders in fire alarm systems. When the fire alarm activates, it cuts power to the door holder, allowing fire doors to close automatically.

How many door holders can it power?

The 2A output capacity provides 48W at 24V DC. A typical electromagnetic door holder draws 0.5-1.5A depending on holding force, so the unit can power one high-force holder or two lower-rated units wired in parallel.

Does it need to be installed by a qualified electrician?

Yes. The unit connects to 230V mains and forms part of a fire alarm system. Installation must comply with BS 5839 and local building regulations, and should be carried out by a qualified fire alarm or electrical installer.

Can it be surface-mounted?

Yes. The unit includes a wall-mount plate with fixing holes for screwing to walls, inside cupboards, or onto vertical surfaces close to the door location. The 105mm x 105mm footprint fits most service areas.
