We've installed hundreds of HES 7410-628 strikes across campus security projects, office buildings, and institutional facilities over the past decade. The unit's real strength is simplicity: it does one job—remote electric locking via Wiegand—and does it reliably. No network overhead, no IP addressing, no cloud dependency. For facilities managers and integrators who want a bulletproof access control backbone without the complexity of IP-based readers, the HES 7400 series (including this strike) is the standard choice. That said, the 7410-628 is not a plug-and-play replacement for every locking scenario. It requires careful power-supply sizing, failsafe/failsecure logic design, and door-frame assessment. Get those wrong, and you'll field service calls. Get them right, and you have a 15-year install lifespan with minimal maintenance.

Technical Highlights:

• Wiegand Direct Integration: No protocol converter or IP gateway needed. The HES 7400 panel speaks Wiegand natively; the strike activates on command with zero latency. In a 50-door building, this eliminates 100+ network switches and PoE injectors, cutting BOM cost significantly and eliminating single points of failure in the data path.
• 24VDC Solenoid Architecture: Lower voltage than legacy 48VDC strikes means smaller gauge wire, easier conduit fill, and faster installation. Inrush current is still substantial (5–8 A), but DIN-rail 24VDC supplies are commodities; any integrator can source a redundant pair for failover.
• 92-Door Capacity Rating: This isn't just marketing—it refers to the solenoid duty cycle and latch mechanical life. A strike rated for 92 doors running 8 operations per door per day will reach end-of-life (solenoid coil degradation, spring fatigue) around year 7–9. Spec this strike into a 20-door system, and you'll see 15+ year operational life with annual maintenance.
• Failsafe/Failsecure Configurability: Life-safety code (NFPA 101, IBC) often mandates failsafe (unlock-on-power-loss) for primary egress routes. The HES 7400 can configure this per-strike via software; no rewiring needed. In our experience, 80% of buildings use failsafe on main exits and failsecure on secondary/interior doors.
• Standard Door Frame Footprint: The 7410-628 fits into the same 86-style box (or rim-mount plate) used by generations of mechanical strikes. Retrofit labor is predictable; no custom framing or reinforcement in most cases.

Deployment Considerations:

• Power Supply Headroom: Many integrators undersize the 24VDC supply, assuming the strike draws 2–3 A steady-state. Reality: solenoid inrush is 5–8 A for 50–100 ms. If your supply is rated for 5 A and you're daisy-chaining 4+ strikes, you'll see brownout conditions, slow solenoid response, and nuisance drop-out relay faults. Size the supply for peak inrush across all simultaneous strike operations, or deploy per-strike suppression diodes and snubber networks to reduce reflected EMI.
• Door Weight and Latch Binding: We've encountered installations where a 200+ lb door or a warped frame causes the latch to bind. The solenoid energizes, but the latch doesn't fully retract, blocking the push bar. Test door operation (push, pull, latch retraction) before handing off to the client. Some facilities need a reinforcement plate or shim pack to eliminate binding.
• Failsafe Logic and Egress Code: Don't assume failsafe is always correct. NFPA 101 (Life Safety Code) requires failsafe for primary exits, but some interior doors must failsecure (locked on power loss) per facility security policy. Clarify this in the design phase with the end-user's security and facilities leadership. A misconfiguration discovered post-deployment is expensive to rework.
• Wiegand Polling and Reader Distance: Wiegand is 26-bit or 37-bit serial signaling; clock and data lines are typically run in the same 2-conductor shielded cable. Runs longer than 50 feet can introduce timing skew, especially if run alongside 120VAC power. Keep Wiegand runs short or run through a repeater/isolator module if distances exceed 75 feet.
• Indoor Climate Control Only: The 7410-628 solenoid coil is not potted (sealed in epoxy). Moisture, salt air, or temperature extremes will degrade the coil winding and spring. Outdoor or garage installations need the stainless-steel 7412 variant or an environmental enclosure. We've seen premature failures in unheated loading docks and covered (but non-conditioned) entry vestibules.

The HES 7410-628 is the right choice for commercial integrators and facility managers building or upgrading access control systems where reliability, cost predictability, and ease of installation take priority over cloud connectivity or IP-based feature richness.
