Camden CX-92 Series Double Door Magnetic Locks

No. The CX-92 is a fail-safe magnetic lock, so it releases the moment power is cut. That is how every maglock has to behave for egress, and it means the opening is unsecured during an outage unless the lock is on a supervised or battery-backed supply. If the requirement is a door that stays locked without power, a maglock is the wrong device type and a fail-secure electric strike or electrified lockset is what to specify.

The CX-92 carries no fire rating, so it should not be specified on a labeled fire door opening. The 600 and 1,200 lb models are UL and ULC listed as electromagnetic locks, but that listing is not a fire door label and the two are not interchangeable on an inspection.

Both holding forces are offered on the CX-92 double door lock, and both are UL and ULC listed. The 600 lb magnets suit interior openings and low traffic perimeter doors where the lock is backing up an access control reader rather than resisting real force. The 1,200 lb magnets are what to run on exterior entrances, stairwell doors, and any opening that takes abuse or is a genuine security boundary. Holding force is per leaf, so a 1,200 lb double door set is holding each door at 1,200 lb.

TDS adds an adjustable timer, a lock sensor, a door status switch, a relay and an LED onto the magnet itself. That matters when the access control panel needs to know the real state of the opening: the lock sensor confirms the magnet is actually bonded, the door status switch reports open or closed, and the timer holds release for a set interval after a request to exit. If the panel is only switching power and nothing is monitoring the door, the non-TDS version does the same locking job. Both 600 and 1,200 lb forces are available with or without TDS, in aluminum or black.

Mounting hardware depends entirely on the opening. An inswing door with a flat header takes the magnet and armature direct, but an outswing door needs an L or Z bracket, and a glass or narrow stile aluminum door usually needs a bracket plus spacers to clear the frame. Camden offers a range of brackets and spacers for the CX-92, and they are ordered separately from the lock itself. Confirm swing direction and header depth before you order, because the wrong bracket is the most common reason a maglock install stalls.

Yes, the CX-92 is built to work with any access and egress system. It is a straight DC-powered magnet with no proprietary controller, so the reader, keypad, REX motion sensor or push button simply interrupts power on the lock circuit. Pick the TDS version if your panel needs door status and bond sensing feedback rather than just switched power.

Weather and vandal resistant construction is what the CX-92 is built around, with an aluminum body and onboard MOV surge protection that absorbs voltage spikes on the power line before they reach the magnet coil. That surge protection is worth having on any exterior run where the wiring shares a building with lightning-exposed circuits.

Yes, that is exactly what the CX-92 is for. It is supplied as a double door magnetic lock, with a magnet and armature for each leaf, so a pair of doors is secured from a single order and a single power run rather than buying two single door locks and matching them up. Both leaves get the same holding force, 600 or 1,200 lb, whichever you specify.

It comes down to whether the opening can be prepped and how the door must behave on power loss. A shear lock, such as the ROFU Mini Shear Lock Series that the 21037 U-brackets serve, is concealed in the door and frame and needs that prep done. The Camden CX-92 mounts on the surface of the header over both leaves, is UL and ULC listed in its 600 and 1,200 lb. models, is fail-safe so both leaves release when power drops, and is compatible with all access and egress systems on 12/24 VDC. If the frame cannot be morticed, or the job is a retrofit on an existing double door, the CX-92 is the one that installs without cutting the opening.

Aluminum and black are the two finishes, and both are offered across every combination of holding force and TDS. Black is the usual pick on dark anodized storefront and aluminum on clear anodized frames, so the magnet housing disappears into the header rather than reading as an add-on.

The CX-92 is a commercial device. It is a double door electromagnetic lock in aluminum, UL and ULC listed in both the 600 and 1,200 lb versions, and the description notes the construction has been proven across thousands of installations. That is the profile an institutional or MRO buyer standardizes on across a facility, not a residential add-on lock.
