ROFU 8612 Slide Mounting Maglocks, 1200 LB Holding Force

The 8612 is fail-safe, so it releases the door as soon as power drops. Magnetic locks hold only while energized. That makes it the right choice on egress doors where the fire alarm or a power cut has to free the opening, and the wrong choice where you need the door to stay secure through an outage.

It is a surface mounted lock with a slide-in mounting plate. The plate is fastened to the header first, then the lock body slides onto it, so you are working on the frame face rather than mortising into it. The armature mounts to the door leaf. No cutting into the frame is required for the lock body itself.

Order it if your access control panel or alarm needs to confirm the door is actually secured. The 8612 comes three ways: standard single magnet, single magnet with bond sensor and door status, and standard double magnet with bond sensor and door status. The sensor outputs tell the panel the armature is bonded to the magnet and whether the door is closed. If you are just switching power from a reader or REX with no monitoring back to the head end, the standard single magnet version covers it.

The ROFU 8612 is UL listed for auxiliary locks under file GWXT.R16728, which is an auxiliary lock listing rather than a fire door listing. The Camden CX-91S, CX-92, and CX-DE1200 magnetic locks are likewise not fire rated. On a fire rated opening, positive latching is generally required, so a magnetic lock alone is the wrong tool - specify an electrified latching device instead and confirm with your AHJ.

For a single leaf, the Camden CX-91S Series single door magnetic lock covers the same job. The ROFU 8612 itself is offered in single magnet configurations as well as a standard double magnet version, so if you are already specifying ROFU you can order the single magnet 8612 rather than switching brands. Both are surface mounted electromagnetic locks. Note that neither the ROFU 8612 nor the Camden CX-91S is fire rated, so on a fire door opening you need a different approach.

No. The ROFU 8612 is a fail-safe electromagnetic lock that releases when power is removed; it has no delay timer built in. For a code-driven delayed egress opening on a single door, the Camden CX-DE1200 Series Exit Watch delayed egress magnetic lock is the product built for that function. Confirm the delay sequence with your local authority having jurisdiction before ordering either one.

Yes. The 8612 develops 1200 lb of holding force and is rated for commercial use, which is the common force class for standard perimeter and interior swing doors in offices, multifamily and institutional buildings. Get the armature seated flat against the magnet face and shimmed square, because a misaligned armature is what costs you holding force, not the rating.

No. The 8612 is built with no residual magnetism, so the armature releases cleanly the instant the coil de-energizes instead of clinging to the magnet face. That matters on egress doors tied to a fire alarm release, where any drag on release is a code problem.

For a single leaf, the Camden CX-91S Series is a single door magnetic lock; for a pair, the Camden CX-92 Series is the double door version, which lines up with the 8612's double magnet configuration. If your opening needs delayed egress rather than instant release, neither the 8612 nor the CX-91S does that, and you would want the Camden CX-DE1200 Series Exit Watch delayed egress maglock instead.

Two: Satin Aluminum (US28) and Dark Bronze (US40). Both are available on all three magnet configurations. US28 is the match for clear anodized aluminum storefront, US40 for dark bronze anodized frames. The casing itself is aluminum alloy.
