SDC E1200 Magnetic Lock 1200LBS
Overview
The SDC E1200 is a 1200-pound electromagnetic lock designed for access control integration in commercial and institutional environments. Operating on 24VDC, the E1200 communicates via OSDP protocol, enabling direct integration with modern access control panels and door controllers without intermediate converters or gateways. This wired connectivity eliminates wireless interference concerns and ensures predictable, latency-free operation in high-security deployments.
Key Features
- 1200-pound holding force: Sufficient for standard commercial entry doors, secure perimeter access, and restricted-area server room installations. This rating assumes proper frame installation and typical indoor conditions — verify frame strength and hinge capacity in your specific deployment.
- 24VDC operation: Standard low-voltage power simplifies wiring integration with existing access control infrastructure. Power supply must be sized appropriately for the lock's draw; confirm available amperage before installation.
- OSDP protocol support: Direct communication with certified access control systems eliminates the need for intermediate converters, reducing points of failure and simplifying troubleshooting. OSDP (Open Supervised Device Protocol) is the current standard for door controllers and readers in enterprise access control.
- NFC/13.56MHz credential compatibility: Works with proximity cards, NFC smartphone credentials, and keypad readers. Mixed-credential deployments are straightforward — the E1200 integrates with reader configurations already in use across most modern access control systems.
- Strike-type form factor: Designed for surface mounting on door frames. No mechanical strike plate or additional hardware required beyond standard installation template and fasteners. Verify door opening direction and frame construction before ordering.
- Fail-safe (energize-to-lock) operation: In a power loss or control system failure, the lock defaults to unlocked. If your deployment requires fail-secure behavior (locked in power loss), confirm with the manufacturer or consider an alternative locking strategy before installation.
Integration and Compatibility
The E1200 integrates directly with OSDP-certified access control panels. Typical wiring includes a dedicated 24VDC power supply, OSDP communication line to the panel, and fault monitoring. Installation in high-security areas such as server rooms, secure entry doors, and restricted access zones is straightforward if the door frame and mounting surface meet SDC specifications. Coordinate with your access control integrator to confirm panel compatibility and power supply sizing before commissioning.
Deployment Considerations
The 1200-pound holding force is suitable for standard commercial doors but may require reinforcement for heavy-traffic or high-security applications — assess door weight, hinge capacity, and frame strength independently. The fail-safe default means the lock releases power loss; if your security policy requires the door to remain locked during power events, a different lock type or backup power strategy is necessary. OSDP communication is wired, not wireless, so physical conduit or cable runs must be planned during installation.
Frequently Asked Questions
Q: What is the difference between fail-safe and fail-secure operation?
A: Fail-safe locks unlock when power is lost; fail-secure locks remain locked. The E1200 operates fail-safe. Choose based on your security requirement: fail-safe allows emergency egress during power loss, while fail-secure prevents unauthorized access if power fails.
Q: Can the E1200 be used with wireless access control readers?
A: The lock itself communicates via wired OSDP protocol. Wireless readers (NFC or Bluetooth) can trigger access control panels that then command the E1200 via wired OSDP — the lock's communication is always wired to the control panel.
Q: What power supply do I need for the E1200?
A: A 24VDC power supply is required. Verify the lock's current draw with the manufacturer and ensure your power supply has sufficient capacity. Most commercial access control power supplies are rated for multiple locks; confirm your supply's specifications before installation.
Q: Is the E1200 suitable for outdoor installation?
A: The E1200 is designed for standard commercial indoor environments. Outdoor mounting exposes the lock to moisture, temperature swings, and UV exposure — confirm with the manufacturer that outdoor installation is supported and what additional protective measures may be required.
Q: What mounting surface does the E1200 require?
A: The E1200 is a strike-type lock for surface mounting on door frames. Wood, steel, and aluminum frames are typical; confirm frame material and thickness with the mounting template provided in the datasheet.
Q: Does the E1200 work with all access control panels?
A: The E1200 uses OSDP protocol, which is industry-standard for modern access control systems. Legacy systems using older protocols (Wiegand, 26-bit proprietary) will require a converter or panel upgrade. Confirm your panel supports OSDP before purchasing.

The SDC E1200 hits the right balance for standard commercial access control deployments. The 1200-pound holding force is adequate for typical entry and server-room applications, and OSDP integration with modern panels eliminates converter middleware — a real simplification for integrators. The wired 24VDC protocol keeps the system predictable and eliminates wireless interference variables.
Technical Highlights:
- OSDP direct integration: Communicates natively with certified access control panels over wired protocol. Removes intermediate gateways and simplifies troubleshooting. Worth verifying your panel supports OSDP before ordering.
- 1200-pound strike force: Sufficient for standard commercial frames and typical door weights. Confirm your frame hinge and mounting surface can handle the holding load — undersized installations fail early.
- 24VDC operation: Standard low-voltage infrastructure already in place in most commercial access control installs. Power draw is modest; verify your supply has headroom for multiple locks on the same circuit.
- NFC/proximity credential flexibility: Works with existing proximity and NFC reader ecosystems. Mixed-credential deployments are straightforward — no proprietary middleware required.
Deployment Considerations:
- Fail-safe default: lock releases in power loss. If your security policy requires the door to stay locked during power events, this isn't the right choice — you'll need a fail-secure lock or backup power strategy.
- Surface-mount frame dependency: installation quality is directly tied to frame strength and hinge capacity. Undersized or damaged frames will cause premature failure or loss of holding force. Do a physical site inspection and structural assessment before commissioning.
The E1200 is a solid fit for enterprise entry control, server-room access, and restricted-area doors where OSDP panel integration is already in place and fail-safe operation aligns with your egress and security policy. Don't use it if fail-secure (locked during power loss) is a hard requirement.
