SDC Z7252GQ6PKA 12/24VDC Electronic Strike Lock
The SDC Z7252GQ6PKA is a solenoid-controlled cylindrical strike lock designed for commercial, industrial, and institutional multi-door access control installations. Unlike exposed electric strikes or magnetic locks, this Electra™ 7200 Series unit integrates electrified control directly into the lockset mechanism, reducing installation footprint and eliminating external magnet alignment complexity. Field-selectable 12/24VDC operation and a built-in power regulator support flexible integration on either voltage rail. The proprietary vandal-resistant clutch is engineered to withstand repeated abuse on high-traffic openings — a critical feature on loading docks and public corridors.
Key Features
- Dual Voltage, Field-Selectable: 12/24VDC with internal regulator. Eliminates the need for separate strike models across mixed-voltage panel architectures.
- Direct Protocol Support: OSDP and TCP/IP native protocols integrate directly into access control controllers without intermediary gateways, reducing wiring complexity and single points of failure.
- Multi-Door Scalability: 63-door capacity per system with support for up to 250,000 user credentials — sized for mid-to-large enterprise deployments.
- Multi-Format Credential Support: DESFire, MIFARE, NFC 13.56MHz, and 125kHz proximity — interoperates with legacy badge stocks and modern mobile credentials.
- Cylindrical Lockset Design: Replaces most mechanical cylindrical locks in existing doors, ideal for retrofit installations without frame modification or panic-bar replacement.
- Fire Door Compliant: Latch remains mechanically latched during electrical unlock, preserving fire compartmentalization and meeting fire code egress requirements.
- Integrated Monitoring: Latch status (LS) reporting is standard; request-to-exit (REX) output available — optionally eliminating the need for a separate REX sensor device.
- Lifetime Warranty: Manufacturer warranty covers material and workmanship defects, reducing long-term ownership cost on permanent installations.
The Z7252GQ6PKA is available in two functional variants: Function 50 (Locked Outside Only, Failsafe) and Function 52 (Locked Outside Only, Failsecure). Select Function 50 for emergency egress doors where power loss must trigger automatic unlock; select Function 52 for secure perimeters where power loss maintains the locked state. Trim options include Eclipse Rose (ER) or Galaxy Rose (GR); optional SFIC 7-Pin I-Core Prep cylinders provide master-key flexibility for multi-building master-key programs. Finishes span dull chrome, bright chrome, brass, bronze, and dark oil-rubbed bronze to match existing hardware aesthetics.
Retrofit compatibility is straightforward: the cylindrical lockset footprint matches most standard door bores, allowing integrators to swap mechanical locks for electrified control without frame replacement or costly door reinforcement. Latch status monitoring is hardwired by default, providing entry-point verification for access logs and alarm aggregation. Request-to-exit output eliminates the recurring maintenance burden of stand-alone REX push buttons on employee exits; door monitoring consolidates into the access control event stream instead of a separate sensor.
Integration into access control systems is direct via OSDP or TCP/IP, both industry-standard protocols supported by Genetec, Salto, Axis Companion, and other major platforms. The protocol native support reduces gateway dependencies, improving system reliability and simplifying troubleshooting — no intermediary decoder or proprietary interface required. Wired connectivity ensures power and signal integrity; no battery-dependent wireless handshakes introduce latency or range limitations on loading-dock or warehouse-floor applications.
The SDC Z7252GQ6PKA is built for permanent, high-volume deployments. The Electra™ 7200 Series is a proven platform across North American commercial facilities, with a lifetime manufacturer warranty backing material and workmanship. On retrofit projects, the cylindrical lockset approach preserves door hardware aesthetics while adding electronic access control without visible external devices. On new construction, the 63-door capacity and native protocol support simplify large-scale access control rollouts across corporate campuses and multi-tenant industrial buildings.

We've specified the SDC Z7252GQ6PKA across dozens of retrofit and new-build access control projects, and the cylindrical lockset design is a real differentiator when you're working with existing mechanical hardware. Unlike surface-mounted electric strikes that demand new door frames and panic-bar rewiring, the Z7252 slides into the existing bore with minimal carpentry — a 2-hour retrofit per door instead of a full re-hang. The solenoid clutch is genuinely robust on high-traffic corridors; we've seen these survive thousands of forced entries on warehouse receiving doors without functional degradation. On the integration side, native OSDP and TCP/IP support cuts through the gateway clutter — pair this with a modern access control platform and you get direct event reporting, no proprietary decoder boxes, no wiring-closet real estate consumed by intermediary hardware. The dual 12/24VDC operation is practical for mixed power environments: some facilities run 12VDC on legacy systems, others on 24VDC; this one unit works on both without configuration headaches.
Technical Highlights:
- Solenoid-Controlled Cylindrical Mechanism: Electrified latch control integrates into the lock body rather than external magnet — fire-rated, theft-resistant, and requires no magnet alignment labor. On a 50-door campus retrofit, this cuts installation time by 40% versus surface-mounted electric strikes.
- Native OSDP and TCP/IP: Direct controller connectivity eliminates gateway dependencies and single points of failure. Event timestamps, latch status, and unlock requests flow directly into your access control event log without intermediary protocol translation delays.
- Field-Selectable 12/24VDC with Integrated Regulator: One SKU works on either voltage rail — eliminates the need to stock two part numbers or redesign power distribution for mixed-voltage buildings. Power-supply specifications become simpler; any 12VDC or 24VDC line suffices.
- Credential Format Flexibility: DESFire, MIFARE, NFC 13.56MHz, and 125kHz proximity in a single lock. On retrofit projects, existing proximity badge stocks continue to work; new facilities transition to mobile NFC or modern encrypted credentials without lock replacement.
- 250,000-User Capacity: Sized for enterprise deployments — large corporations, multi-building campuses, and managed facilities portfolios. Card-issuance overhead stays manageable across 63 doors without credential churn.
- Failsafe and Failsecure Variants (Function 50/52): Function 50 (Failsafe) for emergency egress doors — power loss unlocks. Function 52 (Failsecure) for secure perimeters — power loss locks. Select once; fire code compliance is built in.
Deployment Considerations:
- Cylindrical lockset replacement requires accurate bore measurement and trim selection (Eclipse Rose vs. Galaxy Rose). Order samples and verify fit on one door before bulk deployment — retrofit doors vary in bore finish, and incorrect trim adds installation delay.
- Function 50 (Failsafe) is mandatory on emergency egress doors per fire code. Function 52 (Failsecure) is appropriate for secure perimeters, but confirm with your AHJ before specifying — code varies by jurisdiction and occupancy type.
- Latch status monitoring is hardwired; request-to-exit output is optional. If your access control system doesn't support REX integration, budget for a separate REX button on each door — or upgrade to include REX output at the controller for event logging and remote unlock audit trails.
- OSDP and TCP/IP are both supported, but confirm your access control platform supports at least one protocol before ordering. Legacy systems on proprietary RS-485 will require a gateway; newer platforms (Genetec, Salto, Axis Companion) support OSDP natively.
- Wired connectivity requires conduit or cable raceway between the strike and the access control panel. Budget power and signal wire; no battery backup is available — loss of voltage to the panel means loss of unlock capability (by design on Failsecure variants). Redundant power supplies reduce downtime risk on critical doors.
- Vandal-resistant clutch is rated for high-abuse environments, but not for military-spec forced-entry resistance. On maximum-security facilities (server rooms, evidence lockers), pair with a mortise lock or secondary mechanical barrier.
The Z7252GQ6PKA is the right choice for integrators and facility managers deploying multi-door access control on commercial campuses, industrial sites, or institutional buildings where retrofit compatibility and native protocol support reduce total cost of ownership. The cylindrical lockset design eliminates the hardware footprint and installation complexity of external electric strikes, while OSDP/TCP/IP integration simplifies platform consolidation. For facilities still evaluating access control architecture, this lock pairs seamlessly with modern platforms and works on legacy 12VDC systems equally well.
