ROFU 8406M – Frequently Asked Questions

1) Will the ROFU 8406M maglock work on a sliding door, or is it only for swing doors?
Both. The 8406M mini electromagnet is built for sliding or swinging doors, manual or automatic. The magnet mortises into the jamb and the armature plate mortises into the edge of the sliding door, so nothing protrudes into the opening or the track path.
2) How much room do I need to mortise in a ROFU 8406M mini maglock?
Plan the jamb pocket around a magnet body of 7-1/2 x 1-1/2 x 1-1/8 inches (9-1/16 x 1-1/2 x 1-1/8 inches with the extended housing), and the door edge pocket around an armature of 7-1/4 x 1-1/2 x 1/2 inches. That 1-1/2 inch depth is the number that decides whether your jamb and door stile can take it.
3) What happens to a ROFU 8406M maglock when the power goes out or the fire alarm trips?
It unlocks. The 8406M is fail-safe, so it releases the instant power is removed, and it can be tied into the fire alarm to drop on alarm activation. That is the behavior code officials expect on an egress opening, but it also means the door is unsecured during a power loss unless you back it up with a supervised supply.
4) What is the closest alternative to the ROFU 8406M mini maglock at the same holding force?
The DynaLock 2511 is a single mini electromagnetic lock rated at 650 lb holding force, the same figure the ROFU 8406M carries. The 2511 is part of DynaLock's 2500 Series and is described for outswing applications, while the 8406M is a mortise-mounted mini magnet intended for sliding or swinging, manual or automatic doors, with the magnet mortised into the jamb and the armature into the door edge. If the opening is a sliding door, the 8406M mortise arrangement is the one that matches; for an outswing swinging door, the DynaLock 2511 addresses that configuration directly.
5) For an outswing exterior door, should I use the ROFU 8406M or a DynaLock 2511?
The DynaLock 2511 is specified as a single mini electromagnetic lock for outswing openings at 650 lb, so it is the one written for that geometry. The ROFU 8406M is a mortise mini magnet whose magnet housing sets into the jamb and whose armature plate sets into the edge of a sliding door, which suits sliding or swinging, manual or automatic doors where mortise prep is possible. Both release instantly on loss of power, so either can be tied into a fire alarm release, but the mounting prep is what decides the choice.
6) Does the ROFU 8406M run on 12V or 24V, and how much current does it draw?
It takes either. The 8406M is a 12/24 VDC magnet drawing 500 mA at 12 VDC or 250 mA at 24 VDC, so size your power supply and wire run off whichever rail you are already using in the panel.
7) Will a ROFU 8406M mini maglock still release cleanly, or does the door stick after power drops?
No residual magnetism, so the armature lets go rather than clinging when power is cut. On a sliding door that matters more than on a swing door, because there is no closer or spring pushing the leaf away from the magnet.
8) Do I need to buy separate brackets to install the ROFU 8406M?
Mounting brackets come with it, covering both new construction and retrofit into an existing opening. What you supply is the low voltage power, the release device (card reader, REX, push button) and the fire alarm interface wiring.
9) What is the difference between a mini mortise maglock like the ROFU 8406M and a full size surface mount maglock?
A mini mortise magnet hides inside the jamb and door edge, which is the only practical approach on a sliding leaf or where an architect will not accept a bracket hanging off the header. A full size surface mount unit bolts to the header and frame, is faster to install, and carries far more holding force, but it is visible and it does not work on a slider. Choose the 8406M when concealment or a sliding door drives the decision.
10) Is the ROFU 8406M rated for a high traffic commercial opening?
Yes. It is a commercial grade device with a steel housing, called out for high frequency use, which is what you want on a storefront slider or an automatic entrance that cycles all day.
