1,200 lb Double-Door Electromagnetic Lock with Dual Voltage and UL Fire-Door Certification
The Seco-Larm E-941DA-1K2Q is a double-door electromagnetic lock that delivers 1,200 pounds of holding force per door from a single unit. It operates on selectable 12VDC or 24VDC power, drawing 500mA per magnet at 12V or 270mA per magnet at 24V. The anodized aluminum housing, MOV surge protection, and zero residual magnetism make it a durable, reliable choice for commercial access control and security installations. UL294, UL10B, UL10C, and ULC-S104 certifications cover access control, fire resistance, and positive-pressure fire testing.
The E-941DA-1K2Q is designed specifically for double-door openings where both leaves need to be secured with a single locking solution. The fail-safe design releases both doors simultaneously when power is cut, meeting fire code requirements for emergency egress. Each magnet includes a detachable faceplate and adjustable mounting bracket to accommodate variations in door and frame alignment, simplifying installation on both new and retrofit double-door frames.
Where the E-941DA-1K2Q Fits
- Double-door commercial entries where lobby, conference room, or storefront double doors need electromagnetic locking that secures both leaves with a single controller and releases on fire alarm or access control command
- Fire-rated double-door assemblies where UL10B and UL10C certification is required by local fire code, and the lock must release for emergency egress when the fire alarm panel cuts power
- High-security access control points where 1,200 lb of holding force per door ensures the doors stay locked against forced entry attempts, paired with card readers, keypads, or biometric access control systems
What the E-941DA-1K2Q Delivers
- 1,200 lb holding force per door: Each of the two magnets provides 1,200 lb of holding force independently. Both doors lock and unlock together, providing uniform security across the entire double-door opening.
- Selectable 12/24VDC operation: Field-selectable voltage input connects to the most common power supplies in commercial access control systems. Draws 500mA per magnet at 12V or 270mA per magnet at 24V.
- UL294, UL10B/10C, and ULC-S104 certified: Full UL access control listing plus fire-door and positive-pressure fire-test certifications. Meets the requirements for fire-rated door assemblies in commercial and institutional buildings.
- MOV surge protection with zero residual magnetism: Built-in metal oxide varistor protects against voltage spikes. Zero residual magnetism means the door releases cleanly when power is cut, with no magnetic drag on the armature plate.
- Adjustable brackets and detachable faceplates: Both magnets include adjustable mounting brackets and detachable faceplates for flexible installation on standard and non-standard double-door frames.
Are Magnetic Door Locks Secure?
Electromagnetic door locks are one of the most common locking methods in commercial access control because they combine high holding force with fail-safe operation. The E-941DA-1K2Q provides 1,200 lb of holding force per door, which exceeds the force most people can apply to a door. Combined with proper access control (card readers, keypads, or biometric systems), an electromagnetic lock provides the same level of physical security as a mechanical lock while adding remote control, scheduling, and fire alarm integration. The UL294 certification on the E-941DA-1K2Q confirms it meets the access control industry standard for performance and safety.
