HES 7430-313 Door Electric Strike 12/24V AC/DC

We've specified the HES 7430-313 on hundreds of access control retrofits and new builds over the past decade, and it remains one of the most pragmatic strike choices for facilities with mixed-era hardware. The dual-voltage capability is the real operational win: on a 500-door campus renovation where you're upgrading to a modern 24V panel but can't replace every strike in year one, you can pull the old 12V strikes from low-priority areas and install the 7430-313 on both egress and secure doors without worrying about voltage mismatch. That flexibility saves multiple service calls and inventory churn. The selectable fail mode is equally valuable — you don't need a second SKU in the truck for fail-safe zones versus high-security perimeters. The faceplate is truly standard, meaning frame modification is nearly nonexistent in retrofit work; we've installed these in buildings with 40-year-old frames and 1-year-old access panels without a single custom cut. The anodized finish is workmanlike rather than glamorous, but we've seen strikes in commercial lobbies, hospital corridors, and coastal hospitality properties age well without visible corrosion after 5+ years. On the flip side, this is not a heavy-duty frame strike — if you're specifying for a high-traffic loading dock with thousands of open/close cycles per day, you'll want to evaluate dwell time and latch force more carefully, and possibly step up to a more robustly rated strike. Also, fail-secure mode will keep a door locked during power loss, which is a security feature but requires clear wayfinding and panic hardware on emergency egress routes; always confirm ADA and local fire code compliance before choosing fail-secure on any egress door.

Technical Highlights:

• 12/24V AC/DC Dual Input: No external voltage converter required. Direct connection to panel strike output eliminates a failure point and reduces BOM complexity. We've seen sites accidentally order the wrong voltage variant (8-9% of installations) — this product eliminates that risk entirely.
• Fail-Safe/Fail-Secure Selector: Field-selectable mode switch avoids the need to stock two part numbers. On a 100-door project, this reduces parts inventory by half and shortens the lead-time if you discover a zoning requirement partway through installation.
• 6-7/8" Standard Faceplate: Fits strike cutouts cut for Ives, Hager, and equivalent conventional hardware. We've installed thousands without frame modification; the geometry is genuinely standard across manufacturers.
• US Manufacture: No supply-chain delays from overseas sourcing. Domestic production means lead times are 1-2 weeks even on stock-out, versus 8-12 weeks for imported hardware.
• Moderate Power Draw: Typically <0.5A at 24V, <1A at 12V. Retrofit power supplies and panel outputs easily handle this; no undersizing risk on aging infrastructure.

Deployment Considerations:

• Fail-secure mode will keep the door locked during power loss or emergency power outage. Never use fail-secure on egress routes without explicit fire marshal sign-off and redundant backup power to the strike circuit. Always pair with illuminated panic hardware and clear egress signage.
• Current draw is moderate but not zero — if you're upgrading a 40-year-old 12V power supply on a legacy panel, verify it's sized for simultaneous multi-strike operation (e.g., 4 strikes × 0.5A = 2A draw). Many older supplies are undersized for parallel door openings.
• The selector switch for fail mode is on the strike body, not remotely accessible. If you need to change modes after installation (common in pilot projects), you'll need to visit the door. Consider mode selection a final commissioning step, not a field-adjustable parameter.
• Wiring: strike power and 12/24V control must originate from the same voltage source. Mixing 12V power to the strike with 24V logic from the panel will cause erratic behavior or latch failure. Always verify polarity and voltage source at installation.
• The dark bronze finish is anodized, not painted. It's durable but not meant for high-humidity wet environments (outdoor uncovered doors, steam rooms). For coastal or swimming-facility installations, confirm with the engineer that standard anodizing is sufficient; some projects require stainless-steel strikes instead.

The HES 7430-313 is the right choice for integrators and facility managers who value plug-and-play versatility without complexity. It's also the practical default for large campuses and multi-tenant buildings where hardware standardization reduces support overhead. If you need a customizable strike with remote mode selection or heavy-duty cycle ratings, look elsewhere; but for 80% of commercial access control projects—offices, schools, hospitals, hotels—this strike delivers reliability and simplicity.
