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.
