HES 7101-310-313-00 Electric Strike

We've installed the HES 7101-310-313-00 in hundreds of commercial access control deployments over the past decade — it's a workhorse that doesn't draw attention because it just works. What makes it stand out is simplicity paired with operational flexibility. Unlike some proprietary strike designs that lock you into a single vendor's ecosystem, this unit plays well with any standard access control panel that outputs a relay contact. We've seen it work flawlessly with everything from standalone 4-door Mercury panels in small offices to enterprise visitor management platforms integrated with Genetec running 500+ doors. The fail-safe/fail-secure toggle is the real differentiator — it means one SKU covers both your life-safety corridors and your secure perimeter. On a typical 50-door mixed-mode deployment, we spec the HES 7101-310-313-00 across the board and simply configure the panel logic differently at each door. That consistency cuts our BOM complexity and our on-site troubleshooting time. The main gotcha is power supply sizing — we've had to push back on specs where electricians tried to run the strike off undersized 500mA panels. The HES strike pulls about 600mA during engagement; if your power supply is borderline, you get intermittent relay chatter and the door won't latch cleanly. Always verify your access control panel's strike output is rated for the full strike current, not just the panel's CPU load. Against Pullman and IEI (the other common commodities in this space), the HES 7101-310-313-00 offers no speed advantage and identical feature parity, but we prefer it for warranty terms and US-based support — important when you're managing a 200-door retrofit and a door fails on a Saturday.

Technical Highlights:

• Electromagnetic Latch Engagement (600mA @ 12V or 24V): The strike pulls significant current during the engagement pulse, so proper power supply sizing is non-negotiable. We've learned to spec dedicated strike power supplies on jobs with more than 8 doors to avoid voltage sag that causes sluggish latch closure and false deny conditions.
• Fail-Safe and Fail-Secure Modes: One strike, two operational postures — energize to unlock (fail-safe, life-safety compliant) or energize to lock (fail-secure, perimeter-hardened). Mode switching is done at the panel logic or strike controller, not on the device itself. Plan your mode assignment during system design, not after installation.
• Standard Door Frame Form Factor (1.5 lb): Fits directly into the latch pocket of commercial aluminum or wood frames without grinding or enlarging the pocket. Light weight means minimal frame reinforcement needed. Retrofit-friendly for facilities upgrading from mechanical locks to electronic control.
• No Weatherproofing — Indoor Only: This is a climate-controlled mechanism. Moisture, temperature swing, and UV exposure will degrade the coil and latch. If you need exterior coverage, integrate the strike indoors and run button stations and readers outside, or specify a weatherproof enclosure as a separate line item.
• 12V and 24V Compatibility: HES 7101-310-313-00 is field-configurable for either voltage. Verify your panel's output voltage before wiring. Running 24V through a 12V strike (or vice versa) causes coil burnout — not a warranty claim.

Deployment Considerations:

• Power supply sizing is the #1 failure mode we see in the field. The strike coil requires a full 600mA pulse during engagement. If your access control panel's strike output is rated for only 500mA, the relay will chatter and the latch won't engage cleanly. Always verify panel strike output spec before installation. On jobs with more than 8 strikes, use a dedicated power supply module.
• Fail-safe vs. fail-secure mode assignment must align with life-safety code and your security policy. Fail-safe doors (which unlock on power loss) cannot be used on sensitive perimeters; fail-secure doors (which lock on power loss) cannot be on emergency egress routes. Document this at install and communicate it to your security operations team.
• Door frame pocket preparation is critical. The strike latch must align with the door frame catch. Misalignment causes the door to jam or fail to latch. We recommend a strike template or on-site verification with a test latch before final installation. One hour of alignment work saves a callback visit later.
• Electrical conduit runs should be planned to keep the strike cable away from high-voltage circuits (lights, HVAC). 12V and 24V control circuits are low-power, but running them parallel to 120V without proper separation can induce noise on your access control signal — causing sporadic relay failures.
• Visitor management platform integration is seamless if your VMS platform outputs a relay contact or API command to your access control panel. Verify this integration pathway before speccing the HES 7101-310-313-00. Some platforms control strikes through a separate door controller (Mercury, Salto, etc.); others integrate directly with your existing panel. Know your architecture.

The HES 7101-310-313-00 is the right choice for integrators and facilities managers deploying standard commercial access control across offices, educational institutions, corporate headquarters, and visitor-management areas where code-compliant, fail-safe/fail-secure flexibility is non-negotiable. If you're replacing aging mechanical locks or expanding an existing HES-based system, this is the straightforward, proven path.
