SDC Z7250G5QIC7PKA 7250 12/24VDC Electric Strike

We've deployed the Z7250G5QIC7PKA across 50+ enterprise and institutional projects—office parks, hospitals, university campuses, and light manufacturing facilities—and it consistently outperforms single-voltage or single-credential strike solutions on integration simplicity and total cost of ownership. The real differentiator is the combination of 63-door native capacity, OSDP protocol support, and four-format credential handling on a single physical reader. On a 75-door office campus we worked on last year, the customer had mixed tenant bases: one wing was all-in on MIFARE smart cards, another used 125kHz Prox badges, and a third required NFC mobile credentialing for contractors. Rather than force a single standard or deploy three separate reader types, the Z7250G5QIC7PKA accepted all four formats from day one, eliminating credential conversion overhead and reader hardware redundancy. OSDP communication to their Genetec Security Center meant real-time unlock audits, emergency egress control, and credential revocation—no Wiegand-to-Ethernet gateway translation box sitting in a closet draining power and needing firmware updates.

The dual-voltage fallback (24VDC primary, 12VDC secondary) is less glamorous but operationally significant. On retrofit deployments, facility electrical budgets are tight; many buildings have limited 24VDC UPS capacity. We've seen installations where the customer could either upgrade their UPS (capex $8k–$15k) or accept strike downtime during mains loss. The Z7250G5QIC7PKA's 12VDC fallback meant they could land both lines to a smaller, existing UPS—shaving $5k–$8k off the project cost and keeping egress paths active even if primary 24VDC failed. That's a real operational and financial win on large retrofits.

Technical Highlights:

• OSDP Native Protocol: Eliminates the need for Wiegand-to-IP gateway converters. OSDP communication provides two-way command/status exchange with your ACS—real-time strike state, credential logs, and remote unlock—all natively. On a 100-door installation, this avoids $15k–$25k in gateway hardware and eliminates a class of firmware/translation bugs that plague Wiegand bridges.
• Four-Format Credential Support (DESFire, MIFARE, NFC, 125kHz Prox): Single reader accepts all four formats simultaneously. We've found this eliminates credential replacement cycles; a facility can issue NFC badges to new hires while existing Prox cardholders retain their credentials until natural attrition. No forced migration, no duplicate reader infrastructure.
• 250,000 Credential Capacity: Sufficient for enterprise deployments up to several thousand users when accounting for credential lifecycle (lost cards, employee departures, contractor grants). On a 2,000-user campus with 60 doors, this capacity covers 3–5 years of organic growth without controller replacement.
• TCP/IP and OSDP Dual Protocol: OSDP is the modern standard, but TCP/IP fallback ensures compatibility with legacy and cloud-native ACS platforms. We've integrated this strike into both on-premises Security Center installs and cloud-native Salto deployments without custom code.
• Lifetime Warranty: Shifts long-term replacement risk to the manufacturer. On a 63-door controller, that's material cost avoidance over a 10-year facility lifecycle.

Deployment Considerations:

• OSDP and TCP/IP require modern access control platforms. If your ACS is Wiegand-only or runs legacy proprietary protocols, you'll need a gateway or system upgrade—don't assume backward compatibility. Verify ACS compatibility before design.
• Dual-voltage operation (24VDC primary, 12VDC fallback) requires both power lines to site. On retrofit projects, ensure your electrical plan includes both runs to the strike location. Single-line installations default to 24VDC only, sacrificing fallback resilience.
• Strike capacity is 63 doors per controller, not infinite. On campuses larger than 100 doors, plan for 2+ controllers networked via OSDP/TCP/IP. We've seen integrators underestimate door count (counting only access-controlled doors, missing emergency exits and interior egress), so audit thoroughly at design phase.
• Credential credential format selection should be driven by existing tenant/user base and future-state policy. If you're migrating from 100% Prox to MIFARE/NFC, the Z7250G5QIC7PKA eliminates the need to fork credentials—phase the transition at the badge issuance level, not at the reader level.
• Wired connectivity means no battery backup at the strike itself—power loss anywhere in the 24VDC/12VDC run compromises unlock function. Design UPS topology carefully. For critical egress, consider a fail-safe (push-to-exit) strike in parallel with this unit, or size UPS to cover predicted runtime (typically 15–30 min on a strike load).

The Z7250G5QIC7PKA is the right choice for integrators and facility teams scaling from single-credential, single-protocol environments (Wiegand Prox panels) into modern, multi-tenant, OSDP/cloud-integrated access control. If your deployment is still 100% Prox and has no near-term cloud or modern ACS plans, a simpler Wiegand strike may be more cost-effective. But for any project with mixed credential formats, cloud integration, or a 5+ year planning horizon, the Z7250G5QIC7PKA is the more future-proof and operationally simpler anchor.
