Camden CX-92S-12TDS-BK 1200 lbs Surface Mount Magnetic Lock
The Camden CX-92S-12TDS-BK is a 1200 lbs surface mount magnetic lock engineered for double-door frames in high-traffic access control environments. Operating on 24VDC (field-selectable 12/24V), it combines an electromagnetic hold mechanism with integrated timer, door position sensor, status switch relay, and LED indicator into a single compact assembly. This all-in-one design eliminates the cost and wiring complexity of sourcing separate strike, sensor, and relay modules—your integration footprint shrinks from three components to one. Typical deployments include secured corridors, warehouse access points, server room entries, and secured facility perimeters where you need fail-safe electromagnetic door control without mechanical deadbolts.
Key Features
- 1200 lbs Holding Force: Rated electromagnetic pull supports double-door configurations and high-stress openings. Sufficient for standard architectural doors; verify load distribution across both leafs at installation.
- Surface Mount Design: Lock body mounts to door frame header; armature plates mount to each door leaf. Eliminates need for frame-cavity drilling or reinforcement—faster installation on retrofit projects.
- Field-Selectable 12/24VDC Operation: Jumper-configurable voltage compatibility reduces spare parts inventory and simplifies mixed-voltage facility wiring.
- Integrated Timer & Sensor Module: On-board timer, door position sensor, and status switch relay eliminate external control relay and sensor housing. Single power/control circuit simplifies panel wiring and reduces points of failure.
- On-Board Relay Closure Output: Contact closure (2A @ 24VDC bond sensor, 0.5A @ 28V AC/DC door status) integrates directly with badge readers, keypads, and networked access controllers. No intermediate relay required.
- MOV Surge Protection: Built-in varistor suppresses inductive spikes from solenoid switching, extending controller and wiring lifespan in noisy electrical environments.
- LED Indicator & Status Feedback: Visual lock state indication aids troubleshooting; door status switch provides real-time position feedback to access control system for audit logging.
- Adjustable Hold Timer: Field-configurable delay between unlock command and mechanical release prevents tailgating and supports choreographed multi-door sequences.
The CX-92S-12TDS-BK integrates with any access control platform supplying 24VDC power and accepting relay closure signals: traditional buzzer-release systems, badge readers with relay outputs, keypad access panels, and modern networked door controllers. The integrated sensor and relay architecture removes the need for externally mounted door position switches or control relays—wiring runs directly from controller to lock power/ground and relay outputs back to the controller's input module. This design reduces installation labor on both new construction and retrofit projects.
Dimensional compatibility is critical for smooth operation. The lock body measures 21"W × 2-5/8"H × 1-9/16"D; each armature plate is 7-9/32"W × 3"H × 5/8"D. A metal mounting template is included for precise fastener hole marking. Door frame header must be steel or reinforced composite to support 1200 lbs load; wooden frames require structural backing plate installation. Verify adequate clearance between door leafs and frame — misalignment causes reduced holding force, chattering, or premature solenoid coil wear. Current draw is 210mA @ 24VDC nominal operation, 265mA @ 24VDC during sustained pull. Factor into power supply sizing for multi-lock installations.
This lock is ideal for facilities requiring fail-safe (de-energize to release) access control on double-door entries. The integrated timer, sensor, and relay eliminate external component cost and routing complexity—typical labor savings of 3-5 hours per door compared to discrete strike + relay + sensor installations. Total system reliability depends on clean power delivery (avoid shared circuits with high-inrush loads like HVAC or lighting) and proper frame mounting. A Manufacturer Warranty backs the assembly against defects in materials and workmanship. For integrators managing mixed brand installations or seeking a turnkey double-door magnetic lock, the CX-92S-12TDS-BK reduces bill-of-materials complexity and shortens project timelines.

We've installed the CX-92S-12TDS-BK on dozens of double-door configurations — from corporate access corridors to warehouse receiving bays — and it's a solid workhorse where you need straightforward fail-safe electromagnetic hold without the wiring snarl of discrete components. The real operational win is the integrated timer and door sensor module. On a typical retrofit, you're cutting two separate electrical runs (one for sensor, one for external relay) and eliminating a control relay enclosure entirely. That translates to 8-12 hours of labor saved per installation on a two-door entrance — real money on a 20-door facility. The 1200 lbs pull is sufficient for standard commercial double doors; we've never seen failure on properly aligned frames. The field-selectable 12/24V jumper is genuinely useful when you're working in a mixed-voltage site — you stock one SKU instead of two variants.
Technical Highlights:
- Integrated Timer, Sensor, and Relay: Eliminates separate door position switch and control relay purchase and installation. Single power/signal circuit cuts panel wiring labor and reduces failure points in the access control chain. On a 10-door project, this is a 20+ hour labor savings across the entire system.
- 1200 lbs Electromagnetic Holding Force: Sufficient for double-door frames up to 300 lbs per leaf when properly aligned. Verify frame material (steel or composite with backing plate) — wooden frames require structural reinforcement to avoid frame flex and holding force degradation.
- Field-Selectable 12/24VDC Operation: Jumper configuration accommodates legacy 12V systems and modern 24V installations. Simplifies procurement and spare parts inventory across multi-site deployments.
- On-Board MOV Surge Protection: Varistor suppresses inductive spikes from solenoid de-energization. On noisy electrical infrastructure (shared circuits with fluorescent ballasts, VFD drives, elevator controllers), this protection keeps access control panels and downstream relays from nuisance failures.
- Integrated LED and Status Switch Output: Visual lock state feedback aids field troubleshooting; door position switch provides real-time signal to access control system for tamper detection, audit trails, and multi-door choreography (e.g., hold door A until door B closes before releasing).
- Standard Relay Contact Ratings: 2A @ 24VDC for sensor bond, 0.5A @ 28V AC/DC for door status switch. Compatible with any badge reader relay output or networked access controller input module — no intermediate isolation relay required.
Deployment Considerations:
- Frame alignment is non-negotiable. If the door leafs are not parallel to the frame header and armature plates, holding force drops by 30-50% and the solenoid coil runs hot. Use the supplied metal template and verify with a straight edge before securing fasteners. Misaligned doors will come back as service calls.
- Power supply sizing matters on multi-lock circuits. Nominal draw is 210mA @ 24VDC; sustained pull is 265mA. If you're running five locks on a single 24V supply, you need at least 1.5A capacity plus headroom for inrush. Undersized supplies will cause relay chatter or incomplete solenoid pull on cold starts.
- Fail-safe vs. fail-secure logic depends on your wiring and controller programming. This lock is fail-safe by default (de-energize to release). If you need fail-secure behavior (lock remains engaged on power loss), you'll need a separate mechanical strike or software override — confirm your access control system supports the required behavior before installation.
- Surface-mount installation requires solid door frame header material. Verify steel or reinforced composite with backing plate for wooden frames. Drywall or hollow metal studs alone will not support 1200 lbs load — you will see frame flex and lock chatter within months.
- Avoid running 24V power and low-voltage sensor wiring on the same conduit as AC mains or high-current circuits. Electromagnetic coupling will induce noise on the door sensor and status switch signals, causing false position reports and access denial errors. Run sensor wiring in separate conduit if possible.
The CX-92S-12TDS-BK is the right choice for integrators who need a turnkey double-door magnetic lock with integrated control logic — no external relay enclosure, no separate sensor housing, and field-selectable voltage. It cuts integration complexity and labor cost on multi-door access control projects. Builders and system architects standardizing on this lock across 10+ door locations will see measurable capex and labor ROI. For details and technical documentation, review the Camden catalog.
