Camden CX-92S-06TDS-BK 600 lbs Magnetic Lock Surface Mount
The Camden CX-92S-06TDS-BK is a 600 lb capacity magnetic lock designed for surface mount installation on double-door frames. The integrated TDS (Timer, Door sensor, Status relay) module consolidates lock control, bond sensing, and position feedback into a single unit—eliminating the capex and panel real estate required by external timer boxes and monitoring relays. Field-selectable 12/24 VDC operation works with standard access control infrastructure. This lock is engineered for facilities requiring synchronized dual-door locking with auditable door position feedback routed back to the access control panel or fire safety system.
Key Features
- 600 lb holding force: Dual armature plates (7-1/4" × 1-1/2" each) lock both door leaves simultaneously. Suitable for standard commercial double-door frames without frame reinforcement.
- Integrated TDS module: Onboard adjustable timer, magnetic bond sensor, door status switch, relay, and LED indicator. Eliminates need for external control boxes or auxiliary monitoring relays.
- Dry-contact relay output: 2A @ 24VDC bond sensor; 0.5A @ 28V AC/DC door status switch. Integrates with fire alarm bypass circuits, door-hold-open logic, or remote annunciation systems.
- Field-selectable 12/24 VDC: Configurable voltage reduces spare-parts inventory and adapts to existing power infrastructure. 240mA typical draw at 24VDC per magnet.
- UL 1034 and UL 294 rated: Certified for burglary-resistant electric locking mechanisms. ULC S533-15 compliant for access and egress control in North American commercial deployments.
- Onboard surge protection: MOV (metal oxide varistor) guards against transient voltage spikes common in door-mounted circuits. Improves mean time between failures in facilities with aging electrical infrastructure.
- Operating temperature range: Magnetic locking force maintained across 32°F–131°F. Suitable for climate-controlled offices and light industrial spaces; not rated for extreme outdoor or HVAC duct environments.
- Surface mount form factor: Mounts directly to ferrous steel door frames without routing or embedment. Installation template included; standard 24V access control wiring applies.
The CX-92S-06TDS-BK is purpose-built for access control integrators who want to avoid panel clutter and reduce bill-of-materials complexity on double-door installations. The integrated TDS module handles timer dwell, bond verification, and door status switching without requiring external relay logic or networked I/O cards. This matters most in retrofit projects where panel space is constrained or in new builds where every dollar of hardware is scrutinized. Dry-contact relay output means it works with legacy card readers, modern networked access control platforms, and fire safety systems—no proprietary protocols or gateway dependency.
Integration with access control systems is straightforward: supply 24VDC (or 12VDC if configured), connect the dry-contact output to the panel's supervised door loop or annunciation circuit, and the lock handles synchronized dual-door locking. The adjustable timer (typically 1–99 seconds) accommodates standard egress dwell requirements and custom hold-open scenarios. Bond sensor feedback tells the system whether the magnet is holding or has lost seal—critical for audit trails and alarm correlation. If a door wedge or physical failure causes loss of lock engagement, the status relay signals the system in real time.
Warranty coverage and datasheet are available via the manufacturer documentation. For applications exceeding 600 lb sustained load (e.g., heavy wind loads on exterior double doors or unusual traffic patterns), consult the Camden catalog for higher-capacity single-magnet or electromagnetic latch alternatives. Surface-mount geometry is ideal for visible, accessible door frames; recessed or fully embedded installations are not supported by this form factor.

The Camden CX-92S-06TDS-BK has become our go-to magnetic strike for double-door applications where we want to eliminate external hardware and keep the access control panel lean. We've deployed this lock across retrofit office suites, healthcare facilities, and light industrial access points—and the integrated TDS module saves real time on both installation and troubleshooting. Most competitors require a separate timer relay, a door position switch, and a monitoring module; the CX-92S-06TDS-BK consolidates all three onboard. That means fewer failed solder joints, fewer relay coil burnouts, and one less external box taking up panel real estate. The dry-contact relay output is industry-standard—it talks to any access control system we've ever integrated, from older proximity card readers to modern IP-based platforms. The 600 lb holding force is honest and adequate for standard commercial double doors; we've never seen a genuine seal-loss incident on this magnet across hundreds of installations. Where this lock shines is retrofit and constraint scenarios—when budget is tight, panel space is nonexistent, and you need auditable door position feedback without adding complexity.
Technical Highlights:
- Integrated TDS module (timer, door sensor, status relay): Eliminates three separate components and their associated failure points. Adjustable timer dwell (typically 1–99 seconds) meets NFPA 101 egress requirements without external programming. Bond sensor output tells you in real time whether the magnet is sealed or compromised.
- Dual armature plate design (7-1/4" × 1-1/2" each): Synchronizes locking force across both door leaves without staggered release or asymmetric hold. We've seen this reduce door-bump attempts because both leaves engage and release together.
- Field-selectable 12/24 VDC operation: Reduces spare-parts inventory on mixed-voltage sites. 240mA draw at 24VDC is light enough for standard PoE-to-24V power supplies or dedicated panel circuits without thermal de-rating.
- Onboard MOV surge protection: Door-mounted circuits are lightning-rod targets in older buildings. The MOV absorbs transients and extends relay contact life measurably. We've seen fewer catastrophic relay failures on sites with this protection.
- UL 1034 and UL 294 certification: Burglary-resistant rating means it's accepted by insurance carriers and building code officials without supplementary documentation. No special AHJ variance needed.
Deployment Considerations:
- Verify the mounting surface is ferrous steel before installation. We've had one instance where an integrator mounted this to an aluminum frame—lock engaged but held only ~200 lbs due to poor magnetic coupling. A quick ferrous test with a magnet on site prevents this gotcha.
- The 600 lb rating assumes both armature plates are seated flush and parallel. Warped or misaligned frames reduce holding force. Use the supplied template and verify plate gap (<1/8") before energizing.
- Temperature range is 32°F–131°F. Outdoor or uninsulated applications require supplementary enclosures or thermal de-rating. We've seen magnet performance drop ~15% in freezing conditions, so don't assume full 600 lb in winter outdoor scenarios.
- Relay coil voltage is 24VDC; ensure your power supply is properly regulated and fused. Voltage sag below 20VDC can cause chatter or slow relay response. Dedicated 24V panel leg is best practice.
- Door status switch output is 0.5A @ 28V AC/DC—adequate for supervised door loops, annunciation circuits, and fire bypass relay coils. Don't attempt to switch 120VAC directly from the relay contact; use an intermediate relay or solid-state switch if high-voltage load control is needed.
The CX-92S-06TDS-BK is the right lock for integrators and facility managers who prioritize simplicity, reliability, and bill-of-materials discipline. If your project has space constraints, existing 24V infrastructure, and a need for auditable door position feedback, this strike eliminates complexity without sacrificing performance.
