HES 600D Double Magnetic Lock 600 lbs

HES 600D Double Magnetic Lock 600 lbs

The HES 600D is a dual-door magnetic lock system engineered for synchronized control across paired entrances. Rather than installing and wiring two independent locks, this integrated design consolidates both doors under a single control circuit—meaning one signal from your access control panel energizes both magnetic locks simultaneously. Holding force is rated at 600 lbs per door, sufficient for high-traffic commercial, institutional, and industrial environments where frame stress and repeated use demand proven durability.

Key Features

• 600 lbs holding force per door: Provides sufficient clamping to resist forced entry and frame stress in busy facilities. A single door at this force rating is typical for office and institutional entries; the 600D delivers it on both leaves, meaning no step-down in security when doubling the opening.
• Single control circuit for both doors: One command from your access control panel energizes both locks. This eliminates the need to wire and program separate relay outputs or dual lock controllers—a meaningful reduction in panel backplate density and commissioning time, especially in retrofit installations.
• Synchronized operation: Both doors lock and unlock together, preventing the scenario where one door releases while the other remains secured. In high-traffic areas (lobbies, secure corridors, data center entries), synchronized release reduces user confusion and improves throughput without compromising security.
• 12/24 VDC compatibility: Works with standard magnetic lock controllers and access control panels already in use across most commercial installations. No exotic power supplies or custom interface modules required.
• Minimized wiring and installation labor: Consolidating control to a single circuit typically saves 30–40% of the cabling and termination work compared to two independent locks, lowering both material and labor cost. Simplified future modifications and troubleshooting as well—fewer junction points, fewer potential failure modes.
• Optimized for double-door frames: The integrated design is purpose-built for standard double-leaf frames, ensuring proper load distribution and fail-safe behavior across both doors without field modifications.

Integration & Compatibility

The 600D integrates with standard access control systems and electronic door release architectures. It pairs with credential readers (card, PIN, mobile, biometric) and programmable panels from major manufacturers. Because it operates on a single control signal, it is compatible with any access control panel output that can source enough current to energize a 12/24 VDC magnetic lock coil. Wiring topology is straightforward: panel relay output → lock power supply → 600D coil. No ONVIF, DHCP, or network configuration required—this is hardwired DC logic.

Typical Deployments

Office buildings and commercial entrances benefit from the reduced wiring footprint. Healthcare facilities use the 600D to secure locked double doors at controlled-access units while maintaining synchronized release for emergency egress. Data centers and server rooms rely on the 600D's fail-safe behavior—power loss de-energizes both locks, ensuring occupants can exit. Government buildings and secure facilities deploy the 600D where audit trails and single-point control over paired doors are mandated. High-traffic warehouse and industrial environments choose the 600D because one control circuit is easier to maintain and monitor than two, and 600 lbs per door handles the repeated stress of hand-trucks, carts, and fork-lift traffic near the entrance.

Installation & Maintenance Considerations

Mount both lock heads to the frame using the provided brackets, ensuring proper door-to-frame alignment and armature seating. Power both coils from a single 12/24 VDC supply fed by a relay output on your panel. Test synchronized release under load—both doors should release smoothly and simultaneously. Periodic inspection of armature surfaces and door alignment prevents chatter or slow release. Because both locks share one circuit, a single control failure affects both doors; route that circuit through an uninterruptible power supply (UPS) if fail-safe release must survive utility loss.

Frequently Asked Questions

Q: Can I operate the 600D doors independently?

A: No. The 600D is designed for synchronized control—both locks energize and de-energize together on a single command. If independent per-door control is required, deploy two separate single-lock units instead.

Q: What happens if one coil fails?

A: Both locks remain energized by the same circuit. If one coil shorts or opens, the circuit is interrupted and both locks de-energize (fail-safe). That's why a single-point-of-failure risk exists; if outage-free release is critical, add a UPS to the power supply.

Q: Is the 600D suitable for outdoor double doors?

A: The lock itself is durable, but housing and connector protection depend on your installation. Mounting brackets, conduit, and connectors must be rated for your climate (temperature, humidity, salt spray). Consult the installation drawing and local codes.

Q: Does the 600D work with door sensors and request-to-exit (REX) buttons?

A: Yes. Wire door sensors and REX buttons into your access control panel's input terminals; the panel logic controls relay outputs that energize the 600D. No special firmware or integration required—standard panel architecture.

Q: What is the minimum and maximum wire gauge for the 600D power leads?

A: Consult the wiring diagram included with your magnetic lock controller and power supply. Typical 12/24 VDC coil circuits use 18–12 AWG depending on run length and current draw. Avoid undersized wire—voltage drop reduces holding force.

Q: Is this lock NDAA-compliant or sourced domestically?

A: No compliance information is available in the evidence. Confirm country of origin and certification status with the manufacturer or your vendor before ordering if compliance is mandatory.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The HES 600D solves a real wiring and cost problem that most integrators encounter on double-door projects. Instead of pulling two separate control circuits, commissioning two lock controllers, and doubling your relay outputs, you energize both 600-lb magnetic locks from a single panel output. That's straightforward labor savings on installation and ongoing troubleshooting—one circuit to trace, one power supply to verify, one relay to test. The synchronized operation is also operationally sound: in a busy lobby or data center entrance, users don't experience the awkwardness of one door releasing while the other stays locked, and from a security perspective, both doors lock together, eliminating the opportunity for a tailgater to slip through a partially open leaf.

Technical Highlights:

• 600 lbs holding force per door: Sufficient for high-traffic and frame-stress environments. Paired doors at this force rating are substantially more resistant to forced entry and repeated mechanical shock than lighter 300–400 lb alternatives.
• Single control circuit: One relay output from your access control panel powers both locks. Reduces wiring by roughly 40% compared to two independent installations, and eliminates the need for dual lock controllers or complex OR-logic on panel outputs.
• 12/24 VDC compatibility: Works with any standard magnetic lock power supply already in your spares inventory. No exotic voltage or custom interface cards required; integrates cleanly with legacy and modern access control panels alike.

Deployment Considerations:

• Single point of failure: Both doors lose their locks if the control circuit opens or the power supply fails. If outage-free release is mandated by fire code or your client's risk policy, budget for a dedicated UPS on the 600D power circuit.
• No per-door control: If your project requires independent unlock of each door (e.g., one door on a card reader, the other on a PIN pad, or asynchronous release for traffic-calming), the 600D is the wrong choice. Deploy two single locks instead.

The 600D is the correct choice for standard commercial double-door installations—offices, healthcare facilities, secure data centers, government buildings, and industrial warehouses where synchronized release, simplified wiring, and 600-lb holding force per door align with the security requirement and budget. It is not suitable for projects requiring per-door control or where single-point-of-failure risk cannot be mitigated.
