Camden CX-92S-06 600 lbs Surface Mount Magnetic Lock
The Camden CX-92S-06 is a 600 lb electromagnetic surface-mount magnetic lock designed for double-door access control installations in institutional and commercial buildings. Operating at 24VDC (field-selectable 12/24VDC), the lock delivers holding force through constant electromagnetic attraction — meaning it requires continuous power to remain secured and defaults to unlocked on power loss. This fail-safe behavior is essential for life-safety compliance, ensuring occupants can always egress during power failure or emergency. The surface-mount form factor integrates with any access control system capable of switching 12 or 24VDC output, from relay-based controllers and card readers to modern IP-based panels.
Key Features
- 600 lb holding force: Rated for heavy double-door applications (e.g., institutional main entries, high-traffic corridors). Verify door leaf weight and frame rigidity meet the load rating before installation.
- Field-selectable 12/24VDC: Configurable at installation — 12VDC draws 480mA, 24VDC draws 240mA (base load). Eliminates the need for dual-voltage inventory across mixed panel deployments.
- Fail-safe electromagnetic design: Defaults to unlocked on power loss. Complies with life-safety code requirements (IBC, NFPA) for emergency egress without additional battery backup or mechanical override hardware.
- Surface-mount installation: Mounts horizontally across the door frame header using supplied metal template. Minimal frame modification; armature plates attach to the door leaf — suitable for retrofit and new construction.
- Double-sided armature plates: Two armature plates per lock, pre-sized for CX-92S-06 geometry. Mismatched armature models void holding force ratings — use genuine Camden replacement parts only.
- MOV surge protection: On-board metal oxide varistor shields against transient spikes from access control relay switching and 24VDC power supply noise.
- Operating temperature 0–55°C (32–131°F): Standard commercial/institutional HVAC range. Outdoor or untempered applications (loading docks, warehouse exterior doors) may require weatherproofing or thermal management.
- Modular TDS option: On-board timer, lock sensor, door status, and relay output available; increases current draw to 510mA/12V or 285mA/24V. Simplifies wiring for applications requiring timed release or door-status monitoring.
The CX-92S-06 integrates seamlessly with any access control infrastructure that supplies switched 12 or 24VDC output. Relay-based controllers, wiegand card readers with relay modules, and IP-based panels (Salto, Genetec, Axis Door Controller, etc.) all work without additional interface hardware. Power supply sizing is critical — verify your control panel or dedicated lock supply delivers sufficient current at the selected voltage. If TDS modules are added, recalculate current budget (base + optional load).
Surface-mount positioning keeps installation labor low compared to mortise or rim locks, which require frame routing or door-leaf modification. The metal mounting template provided with each lock ensures precise hole placement and repeatable armature alignment. Temperature operating limits (0–55°C) align with typical commercial HVAC design; outdoor doors in cold climates or untempered storage areas should be evaluated for freeze risk or thermal stress on the electromagnet coil. MOV protection is standard, but a properly rated, surge-protected 24VDC supply upstream reduces nuisance lock cycling on noisy or long-run wiring.
The fail-safe default is a life-safety asset, not a liability. Unlike fail-secure locks (which lock on power loss and require mechanical override or battery backup to exit during outage), the CX-92S-06 allows free egress during any power event. This simplifies compliance with building codes and emergency protocols. Facility managers appreciate the reduced dependency on UPS systems — although backup power for access control panels is still standard practice, the lock itself will not trap occupants if power is lost.

We've installed dozens of CX-92S-06 locks across university campuses, hospitals, and office parks — and the appeal is straightforward: it's a no-nonsense 600 lb surface mount that doesn't complicate life-safety strategy. The fail-safe behavior is non-negotiable in most institutional settings; code officials want to see that doors unlock on power loss, period. The CX-92S-06 delivers that guarantee without requiring a battery-backed solenoid or a separate mechanical escape latch. From a total-cost-of-ownership perspective, you're trading the higher capex of a fail-secure solenoid plus UPS module for lower operational complexity and zero risk of a trapping incident. That trade favors the CX-92S-06 in 9 out of 10 commercial installs we see. The field-selectable voltage is a real differentiator — on a campus where some buildings run 12VDC legacy infrastructure and others use 24VDC modern panels, you stock one SKU and configure it on-site. Current draw is modest (240mA at 24VDC is half of a typical card reader), so even aged power supplies rarely struggle. The one caveat: armature plate alignment is less forgiving than a mortise lock. If the frame is racked (twisted) or the door leaf sags, the magnetic gap opens and holding force drops precipitously. We've had callbacks where a facility assumed the lock was faulty — turned out the frame had shifted over winter. Measure and level the frame before installation.
Technical Highlights:
- 600 lb electromagnetic holding force: Sufficient for most double-door institutional entries (interior hallways, main lobbies, conference centers). Verify actual door weight and hinge load capacity — don't assume a frame rated for 600 lbs of door can sustain 600 lbs of magnetic pull if hinges or latch hardware are undersized.
- Fail-safe on power loss: Defaults to unlocked — no battery backup, no mechanical override, no UPS dependency for the lock itself. Eliminates a major operational and code-compliance pain point. Life-safety auditors approve immediately.
- 12/24VDC field-selectable: Set voltage at installation via jumper or switch. Reduces spare-parts inventory and simplifies multi-building campus specs. Current draw scales (240mA at 24V vs. 480mA at 12V), so sizing a shared 12V supply across many locks may require larger gauges; 24V is gentler on wire gauge and voltage drop over long runs.
- Surface-mount installation: No frame routing, no door-leaf mortising — header-mount with armature plates on the door. Retrofit-friendly; typical installation is 30–45 minutes once frame is leveled and template is positioned.
- MOV surge protection on-board: Protects the coil from relay-switching transients and supply ripple. Extends lock life and reduces nuisance drop-outs on noisy wiring or long 24VDC runs (>300 feet). Still verify your access control power supply is regulated ±10% at the lock terminals.
Deployment Considerations:
- Frame must be level and square. A racked or sagging frame can open the magnetic gap and lose holding force even if the lock is energized. Measure and shim before fastening armature plates — don't rely on the frame as-installed.
- Armature plate alignment is critical. Use the supplied metal template exactly; drift of ≥¼ inch between electromagnet face and armature surface reduces holding force measurably. Double-check plate orientation before final fastening.
- Operating temperature 0–55°C — outdoor doors in climates with sustained freezing (<−10°C) may experience coil brittleness or sluggish response. Plan for weatherproofing (heated enclosure, thermal wrap) if the lock is exposed to extreme cold.
- Current draw varies by voltage and TDS module presence. Always verify your access control power supply can deliver base load (480mA @ 12V or 240mA @ 24V) plus any on-board TDS overhead (add 30mA @ 12V or 45mA @ 24V). Undersized supplies cause intermittent drop-outs and lock reset loops.
- Fail-safe is a feature, not a bug. Educate end-users and code inspectors that unlocking on power loss is intentional and compliant. Avoid retrofitting a battery backup or mechanical latch without re-reviewing the life-safety strategy.
The CX-92S-06 is the right choice for institutional and commercial doors where life-safety code compliance, retrofit installation, and straightforward power integration matter more than advanced features. It's not a smart lock, it's not networked — it's a durable 600 lb fail-safe electromagnetic that has been proven across thousands of campus and hospital installations. Integrators and facility managers who value simplicity and code-first design should explore the Camden catalog.
