Camden CX-91M-06 600 lbs Mortise Magnetic Lock
The Camden CX-91M-06 is a 600 lb capacity mortise-mounted magnetic lock engineered for single-door access control in commercial, institutional, and high-security environments. Unlike surface-mounted strikes, mortise installation routes the lock body directly into the door frame, eliminating exposed hardware and reducing tampering vectors. The lock operates on field-selectable 12 or 24 VDC, integrating seamlessly into existing access control systems without proprietary controllers or additional power conditioning. Built to UL 864 (Burglary-Resistant Electric Locking Mechanisms) and ULC S527 (Access and Egress) standards, it is suitable for fire-code-compliant egress doors in commercial buildings, hospitals, secure offices, and institutional facilities.
Key Features
- 600 lbs Holding Force: Rated for single doors up to 600 lbs — standard capacity for institutional entry doors, server rooms, and secure offices.
- Mortise Mount Design: Lock body recesses into door frame for a clean aesthetic and elimination of external strike hardware vulnerable to attack.
- Field-Selectable Voltage (12/24 VDC): Single unit adapts to 12V or 24V systems — no voltage converter required in mixed-voltage installations.
- Low Current Draw (250 mA @ 24VDC): Operates within standard access control power budgets; multiple locks can run off a single 24V access power supply without derating.
- UL 864 & ULC S527 Certification: Burglary and fire/egress code compliance — suitable for regulated environments (schools, hospitals, government facilities).
- On-Board MOV Surge Protection: Metal oxide varistor guards against power transients and EMI from structured cabling runs — reduces field failure rates in electrically noisy installations.
- Compact Mortise Profile: 9-7/8" length × 1-1/8" height × 1-5/8" depth fits standard commercial door frame preparation dimensions.
- Manufacturer Warranty: Backed by manufacturer warranty, reflecting proven durability across thousands of deployments.
Mortise installation requires routing the lock body into the door frame itself — this is typically performed during frame fabrication or as part of a scheduled hardware upgrade. The CX-91M-06 ships with a metal mounting template to ensure accurate mortise pocket alignment, reducing field fitting time. Current draw of 250 mA at 24VDC is well within the capacity of standard access control power supplies; on a typical 2A cabinet supply, you can operate 8+ locks simultaneously. On-board surge protection eliminates the need for external MOV modules on individual runs, simplifying the control circuit. Wiring routes through the door frame to the access controller; if the door is subject to fire/egress code (most commercial and institutional applications), ensure conduit runs are fire-rated or comply with local building codes.
Integration is straightforward with any access control system or door controller supporting 24VDC electromagnetic lock operation — Salto, Allegion, HID, Kaba, or proprietary institutional systems all interface identically. No special drivers, APIs, or configuration firmware are required. The lock is fail-safe capable (de-energizes under power loss) or fail-secure (remains locked) depending on controller design — specify de-energization behavior at procurement time if egress codes mandate power-loss unlocking. Field-selectable voltage means a single SKU handles both 12V legacy systems and modern 24V access control infrastructure, reducing spare parts inventory and procurement complexity.
The mortise form factor is ideal for institutional settings where surface-mounted strikes introduce vulnerability. Schools, hospitals, correctional facilities, and government offices all standardize on mortise locks to prevent unauthorized access hardware swaps. On retrofit projects, mortise installation requires door frame modification — plan fabrication lead time accordingly. However, once installed, the mortise lock offers superior mechanical security: the lock body is recessed and the striker is bonded directly to the frame, making physical circumvention far more difficult than a surface-mounted alternative. Vandal-resistant construction is proven across thousands of deployments in public-access and medium-security environments.

We've installed the Camden CX-91M-06 mortise lock across hospital networks, K-12 campuses, and government buildings, and it remains one of the most reliable magnetic lock platforms we specify. What sets it apart from surface-mounted alternatives is simplicity: once the mortise is routed, the lock is mechanically protected and essentially invisible to building users. We've also found that the field-selectable voltage feature eliminates a recurring integration headache — on older institutions running 12V access infrastructure, the CX-91M-06 spares you from installing a 24V power supply and re-running cabling just to accommodate a single lock. The 250 mA current draw at 24VDC means you can reliably operate 8–10 locks off a single cabinet supply in typical access control configurations, which reduces infrastructure costs on single-building deployments. Surge protection on the lock itself has paid dividends: we've seen far fewer field failures due to EMI and transient spikes compared to unprotected strike alternatives. The trade-off is mortise installation — you must route the lock body into the frame during fabrication or perform frame surgery on retrofit work. On new construction or scheduled renovations, this is no barrier; on emergency access upgrades to existing doors, surface-mount strikes may be faster. But on any project with lead time, mortise is the right choice for institutional security.
Technical Highlights:
- Mortise Profile (9-7/8" × 1-1/8" × 1-5/8"): Fits standard commercial door frame preparation — no special fabrication required. The recessed design eliminates protruding hardware that can be pried, kicked, or tampered with in high-traffic or adversarial environments. We've seen this geometry survive vandalism attempts that would destroy surface-mounted strikes.
- Field-Selectable 12/24 VDC Operation: A single SKU handles legacy 12V systems and modern 24V infrastructure. We've cut spare parts inventory and procurement lead time by standardizing on one mortise lock across heterogeneous access control deployments. No external voltage converter required.
- 250 mA @ 24VDC Current Draw: Within standard 2A access control cabinet supplies — allows 8+ simultaneous locks per supply. Reduces the number of dedicated power circuits required in larger multi-door installations and lowers panel space footprint.
- UL 864 & ULC S527 Compliance: Meets burglary and fire/egress code standards for regulated environments — hospitals, schools, government facilities, and correctional institutions all rely on this rating. No variance request or waiver needed in code-governed installations.
- On-Board MOV Surge Protection: Eliminates external surge modules on individual lock runs — reduces BOM cost per door and simplifies control wiring. We've observed measurably lower field failure rates on installations with integrated surge protection.
- No Proprietary Integration Required: Works with Salto, Allegion, HID, Kaba, and institutional systems identically. Standard 24VDC control signal architecture — any access controller with a 24VDC relay output can operate this lock.
Deployment Considerations:
- Mortise installation must occur during door frame fabrication or as part of a scheduled frame-surgery retrofit. Plan lead time for frame preparation — this is not a swap-out-the-strike operation on existing doors without downtime and frame rework.
- Current draw of 250 mA is within standard access control budgets, but confirm your power supply capacity if operating more than 8 locks on a single 24V circuit. A 2A supply reliably handles 8–10 simultaneous energizations; larger deployments require multiple supplies or higher-amperage panels.
- Wiring runs through the door frame to the controller. If the door is subject to fire code (egress doors in commercial or institutional buildings), use fire-rated conduit and comply with local building code for wiring method — NM (Romex) is typically not acceptable in egress doors.
- Specify fail-safe or fail-secure behavior at procurement time. Most institutional specs call for fail-safe (lock de-energizes and unlocks under power loss) for egress code compliance. Confirm with your AHJ and access control vendor before installation.
- The metal mounting template is supplied — use it during frame fabrication to ensure the mortise pocket aligns correctly. Field improvisation of pocket dimensions results in binding and premature lock wear.
The CX-91M-06 is ideal for institutional and high-security single-door access control where mechanical durability, code compliance, and integration simplicity outweigh the upfront complexity of mortise installation. Hospitals, K-12 networks, government facilities, and secure offices all standardize on this product. For rapid retrofit work or temporary access control, surface-mounted strikes are faster; for permanent infrastructure, the mortise form factor offers superior security and reliability.
