ROFU ROFU 8031-002 – Frequently Asked Questions

1) Will a ROFU 8031-002 shear lock work on a pair of swinging glass doors?
That's exactly what the 8031-002 is built for. It's a shear lock designed for dual swinging doors, and it suits narrow frames and glass door installations. Because the magnet and armature are shear-style and mount into the header, the doors swing both ways rather than being pulled against a stop like a direct-hold mag lock. It can be installed horizontally or vertically, and it's rated commercial.
2) How much gap can there be between the magnet and the armature on a ROFU 8031-002?
1/8 inch, or 3 mm, maximum. That is the number that decides whether the install holds: shear locks are far less forgiving of gap and misalignment than a surface mag, so the door and header have to be shimmed so the armature sits within 1/8 inch of the magnet across the full face. Both bodies measure 10 1/2 x 1 3/8 x 1 5/16 inches, so you need that much continuous pocket in the header and the door top rail.
3) What power supply do I need for a ROFU 8031-002 mag lock?
It runs on 12 or 24 VDC. At 12 VDC it pulls 1.85 A on inrush and holds at 0.45 A; at 24 VDC it's 1.1 A pull-in and 0.25 A holding. Size the supply to the pull-in figure, not the holding figure, and remember it's fail-safe so the supply has to be on the released-by-alarm side of your access control.
4) Which other electromagnetic locks have the bond sensor and door position monitoring the ROFU 8031-002 has?
The ROFU 8031-002 carries both monitoring and bond sensor functions, with a dry reed contact door position sensor and adjustable magnet, plus an SPDT relay output for remote monitoring and a relock delay adjustable from 1 to 6 seconds with 3 seconds as the default. The closest match on feature set is the Schlage Electronics M390RFK, a heavy duty electromagnetic lock at 1500 lbs holding force with door status monitor, magnetic bond sensor, and relock time delay, which is also a direct retrofit for the Locknetics 390+. The Dorma EML310 BA DP 628 pairs bond alert with a door position sensor at 1500 lb. for a single door, and the Dorma EML310 DP 628 is the same lock with the door position sensor only. Both EML310 versions are fire rated and electrically locked, fail safe, matching the 8031-002 fail-safe function.
5) What is the closest equivalent to a ROFU 8031-002 shear lock for a double glass door opening?
The ROFU 8031-002 is a mortise-mounted shear lock rated at 2200 LB holding force, running on 12 to 24 VDC, and it is built for dual swinging doors including narrow frames and glass doors. Within the magnetic lock lines carried alongside it, the double-door options are the Dorma EML320, an electromagnetic lock for double doors at 1500 lb., the DynaLock 2250 Series double electromagnetic lock at 1200 Lb. surface mounted for outswing or inswing single or double doors, and the Alarm Controls 1200D Series double magnetic locks. The difference to plan around is mounting: the 8031-002 is a mortise shear lock that conceals into the frame and needs a maximum 1/8 inch or 3 mm gap between magnet and armature plate, while the EML320, the 2250 Series, and the 1200D Series are surface magnetic locks that sit on the frame face.
6) Does the ROFU 8031-002 provide delayed egress?
No. The ROFU 8031-002 is a fail-safe shear lock that releases instantly when power is disconnected with no residual magnetism, and it may be released upon activation of a fire alarm. Its adjustable timing is a relock delay of 1 to 6 seconds with a 3 second default, which controls how long the lock waits before re-energizing, not a delay on egress. For an opening that requires a timed delay before release, the delayed egress products are the Alarm Controls 1200DE Series delayed egress magnetic lock for a single door and the DynaLock 2101 Series 1200Lb. early warning lock. Those are a different code conversation than the 8031-002 and are specified where the authority having jurisdiction permits delayed egress hardware.
7) Can I monitor door position and lock status on the ROFU 8031-002?
Yes, and it does both. There's an SPDT relay output for remote monitoring, a door position sensor using a dry reed contact with an adjustable magnet, and a bond sensor that tells you the armature is actually bonded to the magnet rather than just powered. Those are two different signals: door closed is not the same as door locked, and on a shear lock the difference matters because a mis-shimmed door can close without bonding.
8) What is the relock delay on the ROFU 8031-002 and can it be changed?
Adjustable from 1 to 6 seconds, factory set at 3. On a shear lock that delay is functional, not a convenience setting: the door has to come fully back to position before the magnet re-energizes, or the armature bangs the magnet face. If your doors are slow closing, take it up toward 6.
9) Does the ROFU 8031-002 give me delayed egress for a stairwell or a retail exit?
No. The 8031-002 has a relock delay of 1 to 6 seconds, which is the time before it re-energizes after release, not a delayed egress timer. If you need a 15 second nuisance-delay device for a controlled exit, the Alarm Controls 1200DE Series is a delayed egress magnetic lock for a single door, and the DynaLock 2101 Series is an early warning lock.
10) Do I need one ROFU 8031-002 per leaf on a pair of doors?
Yes, one per leaf. The 8031-002 is a single shear lock unit, so a pair takes two, each with its own magnet and armature and each drawing its own current. Add it up at the supply: two units at 12 VDC is 3.7 A of inrush and 0.9 A holding, or 2.2 A and 0.5 A at 24 VDC. If you'd rather buy one assembly for a pair, the DynaLock 2250 Series and the Alarm Controls 1200D Series are double-door units, and the Dorma EML320 628 is a double door 1500 lb fail-safe.
11) What is the difference between the ROFU 8031-002 and the Schlage 320M for a concealed mortise application?
Both are mortise-style electromagnetic locks rather than surface mags. The ROFU 8031-002 is a mortise-mounted shear lock at 2200 LB holding force on 12 to 24 VDC, with a 10 1/2 inch by 1 3/8 inch by 1 5/16 inch magnet and matching armature, and it can be installed horizontally or vertically on dual swinging doors, narrow frames, and glass doors. The Schlage Electronics 320M is a compact mortise sliding door electromagnetic lock at 1500 lbs holding force and is rated heavy duty. The deciding factor is door motion: the 320M is built for a sliding door, while the 8031-002 is designed for swinging leaves and needs the armature to close within a maximum 1/8 inch or 3 mm gap of the magnet.
