ROFU 8900 Magnetic Door Holders Flush/Wall Mount Stainless Steel Plate

That's exactly what it's built for. The ROFU 8900 is fail-safe: cut power and the magnet releases instantly, with no residual magnetism holding the door back. It's wired so it drops the door on fire alarm activation, letting the closer swing it shut. This is a hold-open device tied to your alarm panel or smoke detector circuit, not a lock.

Match the voltage to whatever your fire alarm panel or power supply already puts out. The 8900 is ordered as either 12 VAC/VDC or 24 VAC/VDC, and it accepts AC or DC at either. Current draw is 120 mA at 12 VDC and 60 mA at 24 VDC, so on a long run of several holders off one supply, 24V halves your load and gives you less voltage drop over the wire.

The armature that mounts on the door is an adjustable swivel type, so it pivots to seat flat against the magnet face even when the door doesn't close on it dead square. That covers the small out-of-plumb and alignment error you get on real openings. If the armature can't sit flush to the magnet, you lose holding force, so that swivel is what keeps the 80 lb rating real in the field.

No. It's a hold-open device only. The 8900 magnetically holds a door in the open position and lets go on power loss or fire alarm so the door closer can shut it. It provides no latching, no locking, and no access control. If you need to secure the opening electrically, you want a magnetic lock or an electric strike instead.

Three things beyond the holder: a door closer on the opening (the holder only keeps the door open, it does nothing to close it), a 12 or 24 volt power supply matching the version you ordered, and a connection to the fire alarm or smoke detection circuit so power drops on alarm. Wiring is low voltage and the unit takes AC or DC. The magnet body and the swivel armature ship as the holder set; blocking or backing in the wall for the mounting is a jobsite item.

Both are fail-safe electromagnetic door holders that drop the door on power loss. The ROFU 8900 is a commercial 80 lb holder offered flush or wall mount, in 12 or 24 VAC/VDC, with a stainless plate. The Sargent 1560 is the heavy duty, Grade 1 unit from the 1530 Series. If you're standardizing a building on Grade 1 hardware or dealing with heavy or wind-loaded doors, the Sargent is the one to spec; for standard corridor and office doors the 8900 does the job.

No. There is no residual magnetism, so the instant power drops the armature lets go clean and the door is free to close. That's the behavior code officials look for on a hold-open, since a holder that keeps a partial grip after power loss can stop a fire door from latching.

The ROFU 8900 is ordered in a wall mount configuration as well as a flush mount one, and in either a 12 VAC/VDC or a 24 VAC/VDC coil, so a 24 volt wall mounted replacement is a direct order from the 8900 family, drawing 60 mA at 24 VDC. Its adjustable swivel armature takes up alignment differences between the door mounted armature and the wall plate. The Sargent 1560 is the other fail-safe electromagnetic door holder to consider, from the 1530 Series and rated Grade 1 heavy duty; confirm its mounting and voltage against the existing back box before ordering it as the swap.

Yes, and that's a common way to standardize. The 8900 comes in both flush and wall mount bodies, so you can recess them where the wall allows and surface-mount them where it doesn't, while keeping one part family, one stainless finish, and one holding force across the property. Just keep the voltage consistent with the panels feeding each zone, 12 or 24 VAC/VDC.
