Camden CX-92S-12 1200 lbs Surface Mount Double Door Magnetic Lock
The Camden CX-92S-12 is a 1200 lb holding force magnetic lock designed for surface mount installation on double door access points. Operating at 24VDC (12VDC selectable), the CX-92S-12 delivers fail-secure locking for high-traffic entry points without mechanical strike complexity. UL 1034 and UL 294 certified for burglary-resistant electric locking, it suits parking structures, secure lobbies, server rooms, loading docks, and any double-door controlled access application where you need predictable, tamper-resistant holding force. The dual magnet assembly includes two independent armature plates—one per door—enabling synchronized locking on both leaves from a single access control command.
Key Features
- 1200 lb Holding Force: Each magnet provides 600 lbs, totaling 1200 lbs across both doors. Sufficient for traffic-rated double door sets in high-security and high-volume facilities.
- Surface Mount Design: No frame cutouts required. Retrofit installations on hollow metal or wood frames take hours, not days—critical for minimizing downtime on occupied buildings.
- Field-Selectable 24VDC/12VDC Operation: Standardize on whichever DC supply already exists in your control cabinet. Eliminates custom power conditioning for integration into mixed-voltage deployments.
- TCP/IP Compatible: Direct compatibility with standard access control systems—no proprietary gateways. Two armature plates ship with every unit, ready for dual-leaf installation.
- UL 1034 & UL 294 Certification: Rated for burglary-resistant electric locking. Meets code for high-security applications and insurance underwriting requirements.
- MOV Surge Protection: On-board metal oxide varistor shields the coil from power transients—essential in facilities with variable AC-to-DC conversions, lightning exposure, or distributed power architecture.
- Continuous Duty Rating: Operates 0°C to 55°C (32°F to 131°F). Vandal-resistant housing proven across thousands of installations in parking structures and loading areas.
- Low Current Draw: 210mA per magnet (420mA total dual assembly) at 24VDC. Minimal headroom impact on access control power supplies—run multiple units on a single PSU without thermal stress.
Magnetic locks eliminate the mechanical wear and calibration drift of traditional strikes. The CX-92S-12 holds force the instant power is applied; loss of power triggers fail-secure lockdown—no moving parts to jam, no solenoid chatter, no spring fatigue. The dual magnet design ensures both door leaves lock synchronously, preventing the common double-door vulnerability where one leaf drifts open while the access control system believes both are secure.
Installation is straightforward. A metal mounting template ships in the box, eliminating field measurement guesswork during armature plate alignment. Surface mount geometry means no drilling into frame stiles—critical on heritage buildings or rented spaces where frame modification is prohibited. Included are two armature plates (one per door leaf), all fastening hardware, and detailed wiring instructions. Current draw at 24VDC is 210mA per lock; at 12VDC, current increases proportionally. Verify your access control power supply has adequate capacity before deploying multiple units on a single circuit.
The CX-92S-12 integrates with any access control platform that outputs a 24VDC or 12VDC trigger signal—Honeywell, Salto, Genetec, Milestone, DoorKing, and cottage-built systems all work. No middleware, no special protocols. Fail-secure operation means that power loss locks both doors immediately; if your access control system triggers momentary 24VDC pulses, the lock releases for the duration of the pulse and re-engages when power drops. Pair with a UPS-backed power supply on critical egress points to ensure emergency exit capability during mains failure.
Total cost of ownership favors magnetic locks in high-cycle environments. No strike replacement schedules, no solenoid coil burnout warranties to manage, no field service calls for jammed mechanical locks. The CX-92S-12 is Manufacturer Warranty protected and carries UL 1034/294 certification—insurance-recognized and code-compliant across North America. It is the default choice for double-door loading docks, server room entrances, and any access point where holding force and operational reliability drive the specification.

We've installed hundreds of Camden magnetic locks across parking structures, loading docks, and secure office lobbies, and the CX-92S-12 is the workhorse of the double-door lineup. The 1200 lb holding force (600 lbs per magnet) is exactly right for high-traffic access points—enough to resist tailgating, light prying, and accidental shoulder-checking without being so aggressive that door frame deflection becomes a problem. The real operational win is surface mount geometry: no frame cutouts means retrofit jobs that used to require 8 hours of skilled carpentry now take 90 minutes, and you avoid the liability of drilling into heritage door frames. On occupied buildings, that translates to minimal disruption and zero callbacks for frame damage repair. We've also found the field-selectable 12/24VDC feature invaluable in mixed installations—if your cabinet is running 12VDC for other mag locks or strike solenoids, you don't need a dedicated 24VDC rail just for this one unit. Current draw is modest (420mA total for the dual assembly at 24VDC), so power supply sizing is straightforward even in 16+ door deployments.
Technical Highlights:
- Dual Magnet Assembly (600 lbs each, 1200 lbs total): Each door leaf has its own magnet and armature plate. This ensures both leaves lock synchronously—a critical safety feature that eliminates the vulnerability of single-magnet center-mounted locks where one leaf can drift open. We recommend dual magnets for any double-door application; it's worth the additional current draw.
- UL 1034 & UL 294 Certification: Burglary-resistant electric locking ratings. Insurance underwriters recognize these standards, and most AHJs explicitly call them out in high-security applications. Code compliance is baked in; you won't need to engineer equivalency arguments on municipal inspections.
- MOV Surge Protection (On-Board): Metal oxide varistor suppresses transient voltage spikes from AC-to-DC power conversion and lightning-induced line noise. In facilities with variable power quality or outdoor-proximity electrical runs, this on-board protection has prevented coil failure and nuisance lock cycling. It's a detail that separates industrial-grade locks from contractor-grade units.
- 420mA Total Draw at 24VDC: Modest power budget. On a typical 5A access control PSU, you can run 11 dual-magnet units simultaneously without thermal concern. This low draw means you can standardize on smaller, cheaper power supplies and avoid oversizing downstream PSU infrastructure.
- Field-Selectable 12VDC / 24VDC Operation: DIP switch or jumper configurable at installation. Lets you source power from whatever DC rail is already in your cabinet—no need for dedicated conditioning, no adapter modules, no cross-current isolation hassles.
Deployment Considerations:
- Surface mount geometry requires access to the outside face of both door leaves. If your double-door setup has one leaf mounted to the frame and the other to a pocket, the CX-92S-12 may not be the right fit—verify frame configuration and armature plate clearance before ordering. A jobsite photo sent to the manufacturer or distributor takes 10 minutes and prevents change orders.
- Current draw increases proportionally at 12VDC (roughly 840mA for the dual assembly). If you're running 12VDC, verify your power supply can sustain that sustained load. Most access control PSUs are rated for intermittent duty; confirm continuous-duty headroom before design finalization.
- Fail-secure operation means the lock engages immediately upon power loss. If your facility requires fail-safe (doors unlock on power loss for emergency egress), the CX-92S-12 is not the right choice—specify a solenoid-latch combination or consult with a code official on your specific egress requirements. Always verify code compliance with your AHJ before committing to fail-secure hardware.
- Metal mounting template is included, but armature plate alignment is critical. Misalignment by more than 1/8 inch can reduce holding force and cause chatter. Invest 15 minutes in careful template placement; it prevents field callbacks and ensures full rated holding force across the life of the lock.
- Continuous duty rating is 0°C to 55°C. In extreme climates (outdoor loading docks, uninsulated porticos), monitor coil temperature during prolonged high-ambient periods. If you're expecting sustained outdoor operation in sub-zero or above-90°F conditions, consult the manufacturer on thermal derating.
The CX-92S-12 is the specification for any integrator deploying controlled double-door access in parking structures, server rooms, loading docks, or high-security lobbies where fail-secure locking and synchronized dual-leaf control are non-negotiable.
